centos 安装多版本php

参考网址 http://blog.csdn.net/21aspnet/article/details/47658127

关于Linux环境Nginx安装与调试以及PHP安装参考此文即可：http://blog.csdn.net/unix21/article/details/8544922

Linux版本：64位CentOS 6.4

Nginx版本：nginx1.8.0

PHP版本：php5.5.28 & php5.4.44

所谓多版本多版本PHP就是php5.4和5.5以及其他版本在同一台服务器。

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。

安装第二个版本的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

===========================

以上命令可能会报以下错误：

configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution

解决方法：

yum install libxslt-devel* -y

（再执行一次以上命令，错误解决）

（ubuntu 系统的）

 sudo apt-get install libxslt1-dev

============================

# 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

注意：这个命令如果不设置开机启动的话，下次运行时会运行不了程序。就要手动启动了！！！

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.php 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配置如图：

======nginx conf 配置2====================================================

server {
      listen       82;
      server_name  localhost;


location / {
   root /网站根目录/;
   index  index.php;
}


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


location ~ \.php(.*)$  {
   fastcgi_pass   127.0.0.1:9001;

   fastcgi_param  PATH_TRANSLATED  /网站根目录/$fastcgi_path_info;
   include        fastcgi_params;
       }
}

==========================================================

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

=======================================================

防火墙端口设置2

systemctlstart firewalld启动防火墙

systemctlenable firewalld将防火墙设为开机启动

firewall-cmd--add-port=80/tcp开放80端口供nginx使用

firewall-cmd--zone=public --add-port=80/tcp --permanent永久性开启80端口

=======================================================

测试是否成功，查看phpinfo()。通过端口来决定访问的是那个php 版本
