Linux系统下多版本php共存的解决方案(超简单)

自php7问世，身为最新版本控的我马上升级体验，但是由于服务器上还有旧程序在运行，只好部署一个php多版本共存环境。

现有环境是lnmp

– CentOS 6.7

– nginx 1.10.1

– mariadb-10.0.26

– php 7.0.8

为了更好兼容旧的php程序，推荐使用5.4.45. 主要是兼容mysql扩展。

开始安装

首先要下载php-5.4.45.tar.gz源码包。

通过源码安装

# tar xzvf php-5.4.45.tar.gz # cd php-5.4.45 # ./configure –prefix=/usr/local/php54 –with-config-file-path=/usr/local/php54/etc –enable-fpm –with-fpm-user=www –with-fpm-group=www –with-mysql=mysqlnd –with-mysqli=mysqlnd –with-pdo-mysql=mysqlnd –with-iconv-dir –with-freetype-dir=/usr/local/freetype –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir=/usr –enable-xml –disable-rpath –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –enable-mbregex –enable-mbstring –with-mcrypt –enable-ftp –with-gd –enable-gd-native-ttf –with-openssl –with-mhash –enable-pcntl –enable-sockets –with-xmlrpc –enable-zip –enable-soap –with-gettext –disable-fileinfo –enable-intl –with-xsl # make ZEND_EXTRA_LIBS=-liconv # make install # cp php.ini-production /usr/local/php/etc/php.ini

php.ini 配置

post_max_size = 50M upload_max_filesize = 50M date.timezone = PRC short_open_tag = On cgi.fix_pathinfo=0 max_execution_time = 300 disable_functions=passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server

php-fpm.conf 配置

# vim /usr/local/php/etc/php-fpm.conf [global] pid = /usr/local/php54/var/run/php-fpm.pid error_log = /usr/local/php54/var/log/php-fpm.log log_level = notice [www] listen = /tmp/php54-cgi.sock listen.backlog = -1 listen.allowed_clients = 127.0.0.1:9001 listen.owner = www listen.group = www listen.mode = 0666 user = www group = www pm = dynamic pm.max_children = 40 pm.start_servers = 20 pm.min_spare_servers = 20 pm.max_spare_servers = 40 request_terminate_timeout = 100 request_slowlog_timeout = 0 slowlog = var/log/slow.log

注意：重点是配置监听端口和进程

启动 php-fpm

# cp sapi/fpm/init.d.php-fpm /etc/init.d/php54-fpm # chmod +x /etc/init.d/php54-fpm # /etc/init.d/php54-fpm start

修改nginx配置，对需要的服务配置使用php-5.4.45

location ~ [^/].php(/|$) { try_files $uri =404; fastcgi_pass unix:/tmp/php54-cgi.sock; fastcgi_index index.php; include fastcgi.conf; }

配置php-5.4.45 的php54-fpm 开机自动启动

# chkconfig –add php54-fpm # chkconfig php54-fpm on

chkconfig 功能说明：检查，设置系统的各种服务。

语法：chkconfig [–add][–del][–list][系统服务]

chkconfig [–level <等级代号>][系统服务][on/off/reset]

本方案的重点是

每个PHP版本都要安装在新的独立的文件夹里

每个PHP版本的php-fpm.conf配置文件都需要设置不同的进程名和监听端口

nginx配置文件中指定要使用的PHP版本监听端口或进程名
