Linux系统下为Nginx安装多版本PHP

我们在安装配置服务器LNPM环境时应该考虑到PHP多版本并存的问题，下面是实现Linux系统下为Nginx安装多版本PHP的实现方法

linux版本：64位CentOS 6.4

Nginx版本：nginx1.8.0

php版本：php5.5.28 & php5.4.44

注意假如php5.5是主版本已经安装在/usr/local/php目录下，那么再安装其他版本的php再指定不同安装目录即可。

安装PHP

# wget http://cn2.php.net/get/php-5.4.44.tar.gz/from/this/mirror
# tar zxvf php-5.4.44.tar.gz
# cd php-5.4.44
#./configure --prefix=/usr/local/php5.4.44 \
--with-curl \
--with-freetype-dir \
--with-gd \
--with-gettext \
--with-iconv-dir \
--with-kerberos \
--with-libdir=lib64 \
--with-libxml-dir \
--with-mysql \
--with-mysqli \
--with-openssl \
--with-pcre-regex \
--with-pdo-mysql \
--with-pdo-sqlite \
--with-pear \
--with-png-dir \
--with-xmlrpc \
--with-xsl \
--with-zlib \
--enable-fpm \
--enable-bcmath \
--enable-libxml \
--enable-inline-optimization \
--enable-gd-native-ttf \
--enable-mbregex \
--enable-mbstring \
--enable-pcntl \
--enable-shmop \
--enable-soap \
--enable-sockets \
--enable-sysvsem \
--enable-xml \
--enable-zip
# make && make install
# cp -R ./sapi/fpm/php-fpm.conf /usr/local/php5.4.44/etc/php-fpm.conf
# cp php.ini-development /usr/local/php5.4.44/lib/php.ini
# cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm5.4.44

修改php-fpm.conf的侦听端口为9001，因为主版本5.5.28是侦听9000。

; Note: This value is mandatory.
listen = 127.0.0.1:9001

启动php-fpm

# /etc/init.d/php-fpm5.4.44

php安装成功查看进程

#ps aux|grep php

这样就已经起好php-fpm了。

配置Nginx

增加一段新的端口8054的配置并指向到9001以及指定目录即可：

server {
    listen    8054;
    server_name localhost;

    location / {
      #root  html;
root /usr/www5.4.44;
      index index.html index.htm;
    }

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

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9001;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME /usr/www5.4.44$fastcgi_script_name;
}

  }

nginx的配置文件nginx.conf在

# cd /usr/local/nginx/conf

完整的nginx配置如下：

#user nobody;
worker_processes 4;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid    logs/nginx.pid;

events {
  worker_connections 1024;
}

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

  #log_format main '$remote_addr - $remote_user [$time_local] "$request" '
  #         '$status $body_bytes_sent "$http_referer" '
  #         '"$http_user_agent" "$http_x_forwarded_for"';

  #access_log logs/access.log main;

  sendfile    on;
  #tcp_nopush   on;

  #keepalive_timeout 0;
  keepalive_timeout 65;

  #gzip on;

  server {
    listen    80;
    server_name localhost;

    #charset koi8-r;

    #access_log logs/host.access.log main;

    location / {
      #root  html;
			root /usr/www;
      index index.html index.htm;
    }

    #error_page 404       /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page  500 502 503 504 /50x.html;
    location = /50x.html {
      root  html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #  proxy_pass  http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #  root      html;
    #  fastcgi_pass  127.0.0.1:9000;
    #  fastcgi_index index.php;
    #  fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
    #  include    fastcgi_params;
    #}

		location ~ \.php$ {
		root html;
		fastcgi_pass 127.0.0.1:9000;
		fastcgi_index index.php;
		include fastcgi_params;
		fastcgi_param SCRIPT_FILENAME /usr/www$fastcgi_script_name;
		}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #  deny all;
    #}
  }

	server {
    listen    8054;
    server_name localhost;

    location / {
      #root  html;
			root /usr/www5.4.44;
      index index.html index.htm;
    }

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

		location ~ \.php$ {
		root html;
		fastcgi_pass 127.0.0.1:9001;
		fastcgi_index index.php;
		include fastcgi_params;
		fastcgi_param SCRIPT_FILENAME /usr/www5.4.44$fastcgi_script_name;
		}

  }

  # another virtual host using mix of IP-, name-, and port-based configuration
  #
  #server {
  #  listen    8000;
  #  listen    somename:8080;
  #  server_name somename alias another.alias;

  #  location / {
  #    root  html;
  #    index index.html index.htm;
  #  }
  #}

  # HTTPS server
  #
  #server {
  #  listen    443 ssl;
  #  server_name localhost;

  #  ssl_certificate   cert.pem;
  #  ssl_certificate_key cert.key;

  #  ssl_session_cache  shared:SSL:1m;
  #  ssl_session_timeout 5m;

  #  ssl_ciphers HIGH:!aNULL:!MD5;
  #  ssl_prefer_server_ciphers on;

  #  location / {
  #    root  html;
  #    index index.html index.htm;
  #  }
  #}

}

重启nginx

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

注意需要防火墙增加新端口的开启，不然无法访问：

防火墙配置

注意如果你希望在本地机器例如xp访问虚拟机的网页，如果是centos6需要修改防火墙启动80端口

# cd /etc/sysconfig

修改iptables文件，或者直接用vim编辑

# vim /etc/sysconfig/iptables

添加下面一行，打开防火墙80端口:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8054 -j ACCEPT

重启防火墙

# /etc/init.d/iptables restart

测试是否成功，查看phpinfo()

以上即是Linux系统下为Nginx安装多版本PHP的方法，希望对大家有用
