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

php.ini 配置
<code>post_max_size = <span>50</span>M upload_max_filesize = <span>50</span>M date.timezone = PRC short_open_tag = On cgi.fix_pathinfo=<span>0</span> max_execution_time = <span>300</span> disable_functi>exec,<span>system</span>,<span>chroot</span>,scandir,chgrp,<span>chown</span>,shell_exec,proc_open,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,<span>readlink</span>,<span>symlink</span>,popepassthru,stream_socket_server</code>
php-fpm.conf 配置
<code><span># vim /usr/local/php/etc/php-fpm.conf</span></code>
<code>[global] pid = /usr/local/php54/var/run/php-fpm<span>.pid</span> error_log = /usr/local/php54/var/log/php-fpm<span>.log</span> log_level = notice [www] listen = /tmp/php54-cgi<span>.sock</span> listen<span>.backlog</span> = -<span>1</span> listen<span>.allowed</span>_clients = <span>127.0</span><span>.0</span><span>.1</span>:<span>9001</span> listen<span>.owner</span> = www listen<span>.group</span> = www listen<span>.mode</span> = <span>0666</span> user = www group = www pm = dynamic pm<span>.max</span>_children = <span>40</span> pm<span>.start</span>_servers = <span>20</span> pm<span>.min</span>_spare_servers = <span>20</span> pm<span>.max</span>_spare_servers = <span>40</span> request_terminate_timeout = <span>100</span> request_slowlog_timeout = <span>0</span> slowlog = var/log/slow<span>.log</span></code>
注意：重点是配置监听端口和进程
启动 php-fpm
<code><span># cp sapi/fpm/init.d.php-fpm /etc/init.d/php54-fpm</span><span># chmod +x /etc/init.d/php54-fpm</span><span># /etc/init.d/php54-fpm start</span></code>
修改nginx配置，对需要的服务配置使用php-5.4.45
<code> location ~ [^<span>/]\.php(/</span>|<span>$)</span>
{
try_files <span>$uri</span> =<span>404</span>;
fastcgi_pass <span>unix:</span>/tmp/php54-cgi.sock;
fastcgi_index index.php;
<span>include</span> fastcgi.conf;
}</code>配置php-5.4.45 的php54-fpm 开机自动启动
<code><span># chkconfig --add php54-fpm</span><span># chkconfig php54-fpm on</span></code>
').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });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]
