LNMP-PHP安装

一、安装PHP

 

1：下载Php源码包

[root@ghs src]# wget --no-check-certificate http://cn2.php.net/distributions/php-5.6.30.tar.gz

 

2：创建php-fpm用户

[root@ghs src]# useradd -s /sbin/nologin php-fpm

 

3：初始化

[root@ghs php]# cd php-5.6.30

[root@ghs php]# ./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl --with-openssl

 

过程出现的错误：

configure: error: Please reinstall the libcurl distribution -easy.h should be in <curl-dir>/include/curl/

解决方法：yum install -y libcurl-devel

configure: error: libxml2 not found. Please check your libxml2 installation.

解决方法：yum install -y libxml2-devel

configure: error: cURL version 7.15.5 or later is required to compile php with cURL support

解决方法：yum install -y curl-devel

configure: error: jpeglib.h not found.

解决方法：yum install -y  libjpeg-devel

configure: error: png.h not found.

解决方法：yum install -y libpng-devel

configure: error: freetype-config not found.

解决方法：yum install -y freetype-devel

configure: error: mcrypt.h not found. Please reinstall libmcrypt.

解决方法：先安装epel源，yum install -y epel-release，借助epel源再安装libmcrypt-devel

yum install -y libmcrypt-devel

 

4：开始编译php环境

[root@ghs php]# make

 

5：安装已经编译完成php环境

[root@ghs php]# make install

 

6：拷贝环境及启动脚本

[root@ghs php]# cp php.ini-production /usr/local/php/etc/php.ini

[root@ghs php]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

 

7：设置启动脚本755权限

[root@ghs php]# chmod 755 /etc/init.d/php-fpm

 

8：加入系统服务

[root@ghs php]# chkconfig --add php-fpm

[root@ghs php]# chkconfig php-fpm on

 

9：编写php-fpm的conf文件

[root@ghs php]# vim /usr/local/php-fpm/etc/php-fpm.conf

##加入以下内容，并保存

[global]

pid = /usr/local/php/var/run/php-fpm.pid

error_log = /usr/local/php/var/log/php-fpm.log

[www]

listen = /tmp/php-fcgi.sock

user = php-fpm

group = php-fpm

pm = dynamic ##表示动态的管理下面的

pm.max_children = 50 ##表示子进程最大50个

pm.start_servers = 20 ##表示一开始启动：20

pm.min_spare_servers = 5 ##表示空闲最小不能低于5个

pm.max_spare_servers = 35 ##表示空闲时最大不能大于35个

pm.max_requests = 500 ##表示一个子进程在它的生命周期内处理多少个请求500个

rlimit_files = 1024 ##表示每个进程使用描述符的限制1024

slowlog = /tmp/www slow.log ##此参数表示监控作用

request_slowlog_timeout = 1

 

执行/usr/local/php/sbin/php-fpm -t检查配置文件是否有误

如果出现诸如 “test is successful” 字样，说明配置没有问题。

 

10：启动服务

[root@ghs etc]# service php-fpm start

Starting php-fpm done

[root@host2 etc]# netstat -lnpt

Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name

tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 2264/master

tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 77055/php-fpm: mast

tcp6 0 0 ::1:25 :::* LISTEN 2264/master

tcp6 0 0 :::22 :::* LISTEN 1252/sshd

 

二、测试PHP解析

 

1：编写新的测试Nginx虚拟主机conf文件

[root@ghs vhosts]# vim /usr/local/nginx/conf/vhosts/test-php.conf

##以下内容加入到配置文件，/data/www为网站目录

server{

listen 80;

server_name localhost;

root /data/www;

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /data/www$fastcgi_script_name;

include fastcgi_params;

}

}

 

2：写php测试解析文件

[root@ghs vhosts]# vim /data/www/1.php

##加入以下内容到文件

<?php

echo "test php scripts.";

?>

 

3：curl测试解析是否显示test php scripts，则表示成功

[root@ghs vhosts]# curl localhost/1.php

test php scripts
