一、Mysql前面已经安装过 http://vanjle.blog.51cto.com/9794584/1740713

二、安装 PHP

PHP官方下载地址：http://www.php.net/downloads.php

sohu镜像站下载地址：http://mirrors.sohu.com/php/php-5.3.27.tar.gz

1、下载 php 包到 /usr/local/src/

[root@Levan localhost]# cd /usr/local/src/
[root@Levan src]# wget http://mirrors.sohu.com/php/php-5.3.27.tar.gz

2、解压

[root@Levan src]# tar -zxvf php-5.3.27.tar.gz

3、为了防止后面编译后不能正常解析PHP，故先安装需要的软件或者库文件（亲试99%都会成功）

[root@Levan src]# yum install -y gcc gcc-c++ make zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers libtool libtool-ltdl-devel

[root@Levan src]# rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@Levan src]# yum install -y libmcrypt-devel

4、创建相关账户

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

5、配置编译参数

[root@Levan src]# cd php-5.3.27
[root@Levan php-5.3.27]# ./configure \
--prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--enable-fpm \
--with-fpm-user=php-fpm \
--with-fpm-group=php-fpm \
--with-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 \
--enable-zend-multibyte \
--disable-ipv6 \
--with-pear \
--with-curl \
--with-openssl

6、编译

[root@Levan php-5.3.27]# make

7、安装

[root@Levan php-5.3.27]# make install

8、修改配置文件

[root@Levan php-5.3.27]# cp php.ini-production /usr/local/php/etc/php.ini
[root@Levan php-5.3.27]# vim /usr/local/php/etc/php-fpm.conf

[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
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

保存配置文件后，检验配置是否正确：

[root@Levan php-5.3.27]# /usr/local/php/sbin/php-fpm -t

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

9、启动php-fpm

[root@Levan php-5.3.27]# cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@Levan php-5.3.27]# chmod 755 /etc/init.d/php-fpm
[root@Levan php-5.3.27]# service php-fpm start

如果想让它开机启动，执行：

chkconfig php-fpm on

检测是否启动：

ps aux |grep php-fpm

看看是不是有很多个进程（大概20多个）

如果重启的时候报错：

Starting php-fpm [14-Aug-2015 11:29:31] ERROR: An another FPM instance seems to already listen on /tmp/php-fcgi.sock
[14-Aug-2015 11:29:31] ERROR: FPM initialization failed
failed

检测是否启动：ps aux |grep php-fpm

如果有进程，用命令killall php-fpm 杀掉，如果没有进程，就直接删除/tmp/php-fcgi.sock 然后再启动。

三、安装 Nginx

Nginx官方网站：http://nginx.org

1、下载nginx

[root@Levan php-5.3.27]# cd /usr/local/src/
[root@Levan src]# wget http://nginx.org/download/nginx-1.4.4.tar.gz

2、解压nginx

[root@Levan src]# tar -zxvf nginx-1.4.4.tar.gz

3、配置编译参数

[root@Levan src]# cd nginx-1.4.4
[root@Levan nginx-1.4.4]# ./configure \
--prefix=/usr/local/nginx \
--with-http_realip_module \
--with-http_sub_module \
--with-http_gzip_static_module \
--with-http_stub_status_module \
--with-pcre

4、编译nginx

[root@Levan nginx-1.4.4]# make

5、安装nginx

[root@Levan nginx-1.4.4]# make install

6、编写nginx启动脚本，并加入系统服务

[root@Levan nginx-1.4.4]# vim /etc/init.d/nginx //写入如下内容

#!/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

保存后，更改权限:

[root@Levan nginx-1.4.4]# chmod 755 /etc/init.d/nginx
[root@Levan nginx-1.4.4]# chkconfig --add nginx

如果想开机启动，请执行:

[root@Levan nginx-1.4.4]# chkconfig nginx on

更改nginx配置

首先把原来的配置文件清空:

> /usr/local/nginx/conf/nginx.conf

“>” 这个符号为重定向的意思，单独用它，可以把一个文本文档快速清空。

vim /usr/local/nginx/conf/nginx.conf

写入如下内容:

user nobody nobody;
worker_processes 2;
error_log /usr/local/nginx/logs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
worker_rlimit_nofile 51200;

events
{
    use epoll;
    worker_connections 6000;
}

http
{
    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;
    }

}

}

保存配置后，先检验一下配置文件是否有错误存在:

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

如果显示内容如下，则配置正确，否则需要根据错误提示修改配置文件:

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

启动nginx:

service nginx start

如果不能启动，请查看 “/usr/local/nginx/logs/error.log” 文件，检查nginx是否启动:

ps aux |grep nginx

看是否有进程。

测试是否解析php文件

创建测试文件:

vim /usr/local/nginx/html/2.php

内容如下:

<?php
echo "测试php是否解析";
?>

测试:

[root@localhost nginx]# curl localhost/2.php
测试php是否解析

说明php解析正确。

或者我们创建文件：

vim /usr/local/nginx/html/info.php

内容如下:

<?php

phpinfo();

我们在网页上输入192.168.0.109/info.php会显示下图所示的网页（要关机防火墙：iptables -F）：

若报502错误，查看日志

# tail /usr/local/nginx/logs/nginx_error.log

2016/05/23 14:05:18 [crit] 7998#0: *22 connect() to unix:/tmp/php-fcgi.sock failed (13: Permission denied) while connecting to upstream, client: 192.168.18.103, server: localhost, request: "GET /info.php HTTP/1.1", upstream: "fastcgi://unix:/tmp/php-fcgi.sock:", host: "192.168.18.120"

解决方法：

chmod 777 /tmp/php-fcgi.sock

service php-fpm restart

service nginx restart
