本文为大家讲解了如何在Linux,Nginx环境下安装多版本PHP,并支持每个站点不同PHP版本的安装配置方法
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
