两个php在linux上共存,Linux下部署php多版本共存

背景说明

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

1

[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;注意用户名及用户组

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; }

sudo nginx -s reload

sudo /etc/init.d/php55-fpm restart

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 ][系统服务][on/off/reset]
