本文参考了http://blog.s135.com/nginx_php_v6/ 大量内容,感谢张宴!

 我的centos6是64位的版本

 安装步骤:
  (系统要求:Linux 2.6+ 内核,本文中的Linux操作系统为CentOS 5.3,另在RedHat AS4上也安装成功)
  

  一、获取相关开源程序:
    

  【适用CentOS操作系统】利用CentOS Linux系统自带的yum命令安装、升级所需的程序库(RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包,进行安装):

sudo -s
LANG=C
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers
 
我下载的源码包
    

mysql-5.5.25a-linux2.6-x86_64.tar.gz 

imagick-2.3.0.tgz 

PDO_MYSQL-1.0.2.tgz

memcached-1.4.13

eaccelerator-0.9.6.1.tar.bz2 

libiconv-1.14.tar.gz

memcached-1.4.13.tar.gz

nginx-1.3.3.tar.gz 

libmcrypt-2.5.7 

ImageMagick.tar.gz

libmcrypt-2.5.8.tar.gz

mhash-0.9.9.9.tar.bz2

pcre-8.30.tar.bz2

mcrypt-2.6.8.tar.gz

php-5.3.14.tar.bz2

 
二、安装php-5.3.14(FastCGI模式)
  
  1、编译安装PHP 5.2.14所需的支持库:
 
tar zxvf libiconv-1.14.tar.gz
cd libiconv-1.14/
./configure --prefix=/usr/local
make
make install
cd ../

tar zxvf libmcrypt-2.5.8.tar.gz 
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ..

tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../
 
   2、安装mysql-5.5.25a(编译过的版本)
    
    安装在/usr/local/mysql下面,这样的话一些依赖关系都在,免去一些安装麻烦。

shell> groupadd mysql
shell> useradd -r -g mysql mysql
shell> cd /usr/local
shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gz
shell> ln -s full-path-to-mysql-VERSION-OS mysql
shell> cd mysql
shell> chown -R mysql .
shell> chgrp -R mysql .
shell> scripts/mysql_install_db --user=mysql

#出现这样的问题Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

#解决方法:yum install libaio


shell> chown -R root .
shell> chown -R mysql data
# Next command is optional
shell> cp support-files/my-medium.cnf /etc/my.cnf
shell> bin/mysqld_safe --user=mysql &

# mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

#解决方法查看/var/log/mysqld.log

#Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2 - No such file or directory)

#mkdir -p /var/run/mysqld


# Next command is optional
shell> cp support-files/mysql.server /etc/init.d/mysqld

shell> chkconfig --add mysqld

shell> chkconfig mysqld on

 

#mysq反反复复装了几遍,一开始总是不行,我自己怀疑开始安装之前应当把/etc/my.cnf干掉,直接用/usr/local/mysql/my.cnf

进入到mysql command line 下,添加一个root权限的账户

GRANT ALL PRIVILEGES ON *.* TO 'carddev'@'localhost' IDENTIFIED BY 'carddev';
GRANT ALL PRIVILEGES ON *.* TO 'carddev'@'127.0.0.1' IDENTIFIED BY 'carddev';

3、编译安装PHP(FastCGI模式)

  tar zxvf php-5.3.14.tar.gz

  cd php-5.3.14

     

  64位系统要做些软连接

      ln -s /usr/lib64/libldap* /usr/lib/

 

     32位系统:ln -s /usr/local/mysql/lib/libmysqlclient.so.18  /usr/lib/

     64位系统:ln -s /usr/local/mysql/lib/libmysqlclient.so.18  /usr/lib64/

 

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap

make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-development /usr/local/php
cd ../

以下php安装错误来自百度搜索

 安装php的时候,出现cannot stat `ext/phar/phar.phar': No such file or directory

于是我又: cd  ext/phar/
ls -l
结果发现没有phar.phar 这个文件!!于是我怀疑是phar.php ,
cp ./phar.php  ./phar.phar
make install 

 4、编译安装PHP5扩展模块

我将memcache server端和client端都安装在了一台机器上,这样方便测试
  1. 首先安装memcache server
tar zxvf memcached-1.4.13.tg.gz
cd memcache-1.4.13/
 ./configure –prefix=/usr/local/memcached
make
make install
cd ../
 
在这个时候,不一定会编译通过,依旧会出现:
checking for libevent directory… configure: error: libevent is required. You can get it from http://www.monkey.org/~provos/libevent/
If it’s already installed, specify its path using –with-libevent=/dir/
因为libevent 这个包是系统默认安装的,没有安装相应的开发所用的头文件。
所以,还要使用如下命令来安装:
yum install libevent-devel
有的时候会报一些找不到lib包的warning,例如:
  找不到libevent-1.4.so.2
可以建立软连接.也可以用ldconfig来解决这个问题,在/etc/ld.so.conf,添加些常用的lib库路径.
 

  2. 安装memcache client端

    Memcached客户端是基于libmemcached的,所以需先安装libmemcached。

    官网:http://download.tangent.org
    下载最新版本,我下载的是libmemcached-1.0.9
   cd libmemcached-1.0.9
       ./configure --prefix=/usr/local/libmemcached --with-libmemcached-dir=/usr/local/libmemcached
    make && make install
       
   OK,现在安装PHP extension for interfacing with memcached via libmemcached library
         下载地址:http://pecl.php.net/package/memcached
          tar zxvf memcached-2.0.1.tgz 
          cd memcached-2.0.1
    /usr/local/php/bin/phpize
          ./configure --with-php-config=/usr/local/php/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached
    make && make install
           
    
 
 
 

tar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/
/usr/local/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql
make
#make有的时候出错了
#PDO_MYSQL make: *** [pdo_mysql.lo]
#解决方法
# ln -s /usr/local/mysql/include/* /usr/local/include/
make install
cd ../

tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../

tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

 5、修改php.ini文件

  手工修改:查找/usr/local/php/php.ini中的extension_dir = "./"
  修改为extension_dir = "/usr/local/php/lib/php/extensions"

  cp -R /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/*  /usr/local/php/lib/php/extensions
  并在此行后增加以下几行,然后保存:
  
  extension = "pdo_mysql.so"
  extension = "imagick.so"
  extension = "memcached.so"
  

  再查找; cgi.fix_pathinfo=0
  修改为cgi.fix_pathinfo=0,防止Nginx文件类型错误解析漏洞。

 6、配置eAccelerator加速PHP:

mkdir -p /usr/local/eaccelerator_cache
vi /usr/local/php/php.ini


  按shift+g键跳到配置文件的最末尾,加上以下配置信息:

 
[eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/eaccelerator.so"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/usr/local/eaccelerator_cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
 
7、创建www用户和组
/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
chown -R www.www /var/www
 
8、配置php-fpm.conf
 
打开一下两行注释:
 
pid = run/php-fpm.pid
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
 
user = www
group = www
 
到了php5.3.3,默认即支持php-fpm
但是php/sbin/php-fpm的内容发生了变化,之前是一个脚本,现在是一个二进制文件,需要使用信号控制:

master进程可以理解以下信号
SIGINT, SIGTERM 立刻终止
SIGQUIT 平滑终止
SIGUSR1 重新打开日志文件
SIGUSR2 平滑重载所有worker进程并重新载入配置和二进制模块
示例:
 
php-fpm 关闭:
kill -SIGINT `cat /usr/local/php/var/run/php-fpm.pid`
php-fpm 重启:
kill -SIGUSR2 `cat /usr/local/php/var/run/php-fpm.pid`
 
 
注:/usr/local/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload。

 

三、安装Nginx 1.3.3

  1、安装Nginx所需的pcre库:

tar zxvf pcre-8.30.tar.gz
cd pcre-8.30/
./configure
make && make install
cd ../


2、安装Nginx

tar zxvf nginx-1.3.3.tar.gz
cd nginx-1.3.3/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../



3、创建Nginx日志目录

mkdir -p /usr/local/nginx/logs/
chmod +w /usr/local/nginx/logs/
chown -R www:www /usr/local/nginx/logs/

   4、创建Nginx配置文件
  ①、在/usr/local/nginx/conf/目录中创建nginx.conf文件:

rm -f /usr/local/nginx/conf/nginx.conf
vi /usr/local/nginx/conf/nginx.conf

user www www;
worker_processes 8;

error_log /usr/local/nginx/logs/error.log crit;
pid /usr/local/nginx/logs/nginx.pid;

worker_rlimit_nofile 65535;

events {
  use epoll;
  worker_connections 65535;
}

http {
  include mime.types;
  default_type application/octet-stream;

  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32k;
  client_max_body_size 8m;

  sendfile on;
  tcp_nopush on;
  tcp_nodelay on;
  
  keepalive_timeout 65;

  fastcgi_connect_timeout 300;
  fastcgi_send_timeout 300;
  fastcgi_read_timeout 300;
  fastcgi_buffer_size 64k;
  fastcgi_buffers 4 64k;
  fastcgi_busy_buffers_size 128k;
  fastcgi_temp_file_write_size 128k;

  gzip on;
  gzip_min_length 1k;
  gzip_buffers 4 16k;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  gzip_types text/plain application/x-javascript text/css application/xml;
  gzip_vary on;

  include sites/*; #引入所有vhost文件

}

#建立sites文件夹,并在里面建立自己的vhost文件,以我为例

#vim ats.byecity.com

server {
  listen 80 default;   #default表示,访问ip时,会默认进入此vhost下
  server_name atspush.byecity.com;

  charset utf-8;
  root /var/www/atspush/pulic;

  location / {
    index index.html index.htm index.php;
  }

  error_page 500 502 503 504 /50x.html;
    location = /50x.html {
    root html;
  }

  location ~ /static/ {
    rewrite "^/static/(.*)$" /static/$1 break;
  }

  # 不记录 favicon.ico 错误日志
  location ~ (favicon.ico){
    log_not_found off;
    expires 100d;
    access_log off;
    break;
  }

  # 静态文件设置过期时间
  location ~* \.(ico|css|js|gif|jpe?g|png)(\?[0-9]+)?$ {
    expires 100d;
    break;
  }

  location ~ / { 

    rewrite "^(.*)$" /index.php break;
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_param SCRIPT_FILENAME /var/www/atspush/public/index.php;
    include fastcgi_params;
  }

}

 #vim chester.com

server {
  listen 80;
  server_name chester.com;
  index index.html index.htm index.php;
  root /var/www;

  location ~ .*\.(php|php5)?$
  {
    fastcgi_pass 127.0.0.1:9000;
    fastcgi_index index.php;
    include fastcgi.conf;

  }

  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
  {
    expires 30d;
  }

  location ~ .*\.(js|css)?$
  {
    expires 1h;
  }

}

 

②、在/usr/local/nginx/conf/目录中创建fastcgi.conf文件:(这个配置文件一般不需要自己手动添加,在conf下已经有一份fastcgi.conf)

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx;

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

 

5、启动Nginx

ulimit -SHn 65535
/usr/local/nginx/sbin/nginx
 

Nginx启动出错 error while loading shared libraries: libpcre.so.1

[root@localhost conf]# ldd $(which /usr/local/nginx/sbin/nginx)

linux-vdso.so.1 => (0x00007fff227ff000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00000032f3800000)
libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00000032f6000000)
libpcre.so.1 => not found
libssl.so.10 => /usr/lib64/libssl.so.10 (0x00000032fc400000)
libcrypto.so.10 => /usr/lib64/libcrypto.so.10 (0x00000032fa400000)
libdl.so.2 => /lib64/libdl.so.2 (0x00000032f3400000)
libz.so.1 => /lib64/libz.so.1 (0x00000032f3c00000)
libc.so.6 => /lib64/libc.so.6 (0x00000032f3000000)
/lib64/ld-linux-x86-64.so.2 (0x00000032f2c00000)
libfreebl3.so => /lib64/libfreebl3.so (0x00000032f5c00000)
libgssapi_krb5.so.2 => /lib64/libgssapi_krb5.so.2 (0x00000032fb000000)
libkrb5.so.3 => /lib64/libkrb5.so.3 (0x00000032f9800000)
libcom_err.so.2 => /lib64/libcom_err.so.2 (0x00000032f7000000)
libk5crypto.so.3 => /lib64/libk5crypto.so.3 (0x00000032f8800000)
libkrb5support.so.0 => /lib64/libkrb5support.so.0 (0x00000032f9000000)
libkeyutils.so.1 => /lib64/libkeyutils.so.1 (0x00000032f9400000)
libresolv.so.2 => /lib64/libresolv.so.2 (0x00000032f5000000)
libselinux.so.1 => /lib64/libselinux.so.1 (0x00000032f4c00000)

可以看出 libpcre.so.1 => not found 并没有找到,进入/lib目录中手动链接下

[root@localhost lib] cd /lib64
[root@localhost lib]# ln -s libpcre.so.0.0.1 libpcre.so.1
然后在启动nginx  ok 了
[root@localhost lib]# /usr/local/nginx/sbin/nginx
 
另外我在/etc/ld.so.conf下面加了些配置

1 include ld.so.conf.d/*.conf
2 include /usr/lib
3 include /usr/lib64
4 include /usr/local/lib

四、配置开机自动启动Nginx
 
vi /etc/rc.local
ulimit -SHn 65535
/usr/local/nginx/sbin/nginx
 
五、优化Linux内核参数
vi /etc/sysctl.conf

在末尾增加以下内容:
 
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog =  32768
net.core.somaxconn = 32768

net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024  65535


  使配置立即生效:
/sbin/sysctl -p

 

六、在不停止Nginx服务的情况下平滑变更Nginx配置

  1、修改/usr/local/nginx/conf/nginx.conf配置文件后,请执行以下命令检查配置文件是否正确:

  /usr/local/nginx/sbin/nginx -t


  如果屏幕显示以下两行信息,说明配置文件正确:
  the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
  the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully


  2、平滑重启:
  ①、对于Nginx 0.8.x版本,现在平滑重启Nginx配置非常简单,执行以下命令即可:

  /usr/local/nginx/sbin/nginx -s reload



  ②、对于Nginx 0.8.x之前的版本,平滑重启稍微麻烦一些,按照以下步骤进行即可。输入以下命令查看Nginx主进程号:

  ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'


  屏幕显示的即为Nginx主进程号,例如:
  6302
  这时,执行以下命令即可使修改过的Nginx配置文件生效:

  kill -HUP 6302


  或者无需这么麻烦,找到Nginx的Pid文件:

  kill -HUP `cat /usr/local/nginx/nginx.pid`

 

七、编写每天定时切割Nginx日志的脚本
  1、创建脚本/usr/local/nginx/sbin/cut_nginx_log.sh

  vi /usr/local/nginx/sbin/cut_nginx_log.sh


  输入以下内容:

 
#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/usr/local/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/nginx/nginx.pid`


2、设置crontab,每天凌晨00:00切割nginx访问日志

crontab -e


  输入以下内容:

00 00 * * * /bin/bash  /usr/local/nginx/sbin/cut_nginx_log.sh
