MYSQL5.6

PHP5.6

NGINX1.10.3

一、安装Mysql

mysql:
[root@host129 src]#cd
/usr/local/src/ [root@host129 src]# wget https://cdn.mysql.com//Downloads/MySQL-5.6/mysql-5.6.41-linux-glibc2.12-x86_64.tar.gz

二、安装PHP

PHP:
[root@host129 src]#cd /usr/local/src/
[root@host129 src]#wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
[root@host129 src]#tar zxf php-5.6.30.tar.gz
[root@host129 src]# useradd -s /sbin/nologin php-fpm

[root@host129 php-5.6.30]# cp php.ini-production /usr/local/php-fpm/etc/php.ini

Starting php-fpm  done
[root@host129 php-5.6.30]# chkconfig php-fpm on
[root@host129 php-5.6.30]# ps aux |grep php-fpm

三、安装Nginx

NGINX:

NGINX官网https://nginx.org/
[root@host129 src]#cd /usr/local/src/
[root@host129 src]# wget https://nginx.org/download/nginx-1.10.3.tar.gz
[root@host129 src]# tar zxvf nginx-1.10.3.tar.gz 
[root@host129 src]# cd nginx-1.10.3/
[root@host129 nginx-1.10.3]# ./configure --prefix=/usr/local/nginx
[root@host129 nginx-1.10.3]# make & make install

编写nginx启动脚本:
[root@host129 nginx-1.10.3]# vim /etc/init.d/nginx

#!/bin/bash
# chkconfig: - 30 21
# description: http service.
# Source Function Library
. /etc/init.d/functions
# Nginx Settings
NGINX_SBIN="/usr/local/nginx/sbin/nginx"
NGINX_CONF="/usr/local/nginx/conf/nginx.conf"
NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start() 
{
    echo -n $"Starting $prog: "
    mkdir -p /dev/shm/nginx_temp
    daemon $NGINX_SBIN -c $NGINX_CONF
    RETVAL=$?
    echo
    return $RETVAL
}
stop() 
{
    echo -n $"Stopping $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -TERM
    rm -rf /dev/shm/nginx_temp
    RETVAL=$?
    echo
    return $RETVAL
}
reload()
{
    echo -n $"Reloading $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -HUP
    RETVAL=$?
    echo
    return $RETVAL
}
restart()
{
    stop
    start
}
configtest()
{
    $NGINX_SBIN -c $NGINX_CONF -t
    return 0
}
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  reload)
        reload
        ;;
  restart)
        restart
        ;;
  configtest)
        configtest
        ;;
  *)
        echo $"Usage: $0 {start|stop|reload|restart|configtest}"
        RETVAL=1
esac
exit $RETVAL

保存以上脚本更改权限:
[root@host129 nginx-1.10.3]# chmod 755 /etc/init.d/nginx 
添加nginx服务项命令:
[root@host129 nginx-1.10.3]# chkconfig --add nginx
添加完设置启动项:
[root@host129 nginx-1.10.3]# chkconfig nginx on

清空原配置文件:
[root@host129 nginx-1.10.3]# > /usr/local/nginx/conf/nginx.conf

重新写入一下内容:
[root@host129 nginx-1.10.3]#vim /usr/local/nginx/conf/nginx.conf

user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;

worker_rlimit_nofile 51200;

    use epoll;
    worker_connections 6000;

    include mime.types;
    default_type application/octet-stream;
    server_names_hash_bucket_size 3526;
    server_names_hash_max_size 4096;
    log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'
    ' $host "$request_uri" $status'
    ' "$http_referer" "$http_user_agent"';
    sendfile on;
    tcp_nopush on;
    keepalive_timeout 30;
    client_header_timeout 3m;
    client_body_timeout 3m;
    send_timeout 3m;
    connection_pool_size 256;
    client_header_buffer_size 1k;
    large_client_header_buffers 8 4k;
    request_pool_size 4k;
    output_buffers 4 32k;
    postpone_output 1460;
    client_max_body_size 10m;
    client_body_buffer_size 256k;
    client_body_temp_path /usr/local/nginx/client_body_temp;
    proxy_temp_path /usr/local/nginx/proxy_temp;
    fastcgi_temp_path /usr/local/nginx/fastcgi_temp;
    fastcgi_intercept_errors on;
    tcp_nodelay on;
    gzip on;
    gzip_min_length 1k;
    gzip_buffers 4 8k;
    gzip_comp_level 5;
    gzip_http_version 1.1;
    gzip_types text/plain application/x-javascript text/css text/htm 
    application/xml;
    server
    {
        listen 80;
        server_name localhost;
        index index.html index.htm index.php;
        root /usr/local/nginx/html;
        location ~ \.php$ 
        {
            include fastcgi_params;
            fastcgi_pass unix:/tmp/php-fcgi.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
        }    
    }
}

验证一nginx下配置文件:
[root@host129 nginx-1.10.3]# /usr/local/nginx/sbin/nginx -t
内容显示如下正常:
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

(查看一下:
[root@host129 nginx-1.10.3]#ps aux |grep httpd
[root@host129 nginx-1.10.3]#service stop httpd
也可以直接卸载:yum -y remove httpd  )如果没下边启动报错可以不用做这一步

启动Nginx:
[root@host129 nginx-1.10.3]# service nginx start 
StartStarting nginx (via systemctl):  Job for nginx.service failed because the control process exited with error code. 
See "systemctl status nginx.service" and "journalctl -xe" for details

如果报以上错误:
通过查看日志:/var/log/messages这个日志
[root@host129 nginx-1.10.3]# less /var/log/messages

发现nginx端口被占用:
[root@host129 nginx-1.10.3]# ps aux |grep httpd

[root@host129 nginx-1.10.3]# service stop httpd
The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.
[root@host129 nginx-1.10.3]# systemctl stop httpd       
[root@host129 nginx-1.10.3]# service nginx start   
Starting nginx (via systemctl):                            [  确定  ]

查看nginx启动进程:
[root@host129 nginx-1.10.3]# ps aux |grep nginx
root       6248  0.0  0.0  24960   796 ?        Ss   10:38   0:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

验证php解析:
[root@host129 nginx-1.10.3]# vim /usr/local/nginx/html/2.php
<?php
        echo "test php scripts"
?>
[root@host129 nginx-1.10.3]# curl localhost/2.php
test php scripts
证明php解析正常

 四、配置虚拟主机

[root@host129 ~]# vim /usr/local/nginx/conf/nginx.conf
结束符之前:
include vhost
/*.conf; } [root@host129 ~]# mkdir /usr/local/nginx/conf/vhost [root@host129 ~]# cd /usr/local/nginx/conf/vhost/ [root@host129 vhost]# vim default.conf server { listen 80 default_server; server_name yanglt.com; index index.html index.htm index.php; root /data/nginx/default; } [root@host129 vhost]# /usr/local/nginx/sbin/nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful # /usr/local/nginx/sbin/nginx -s reload #makdir -r /data/nginx/default #echo "default_server" > /data/nginx/default/index.html [root@host129 nginx]# curl -x127.9.9.1:80 yanglt.com default_server [root@host129 nginx]# curl -x127.9.9.1:80 ssss.com default_server
