centos php-fpm file not found.,Linux centos系统安装php-fpm时出现问题 Failed to start php-fpm.service: Unit no...

前言：

背景：微信小程序：中玉玉器微商平台。由于这个项目业务扩充，原有的服务器不足以完成现在需求。需要更大的空间和响应速度，原由服务器都不能满足。

原项目架构：Apache(2.4.9)+PHP(5.5.12)+MySQL(5.6.17)；现改：Nginx+PHP(7.0.0)+MySQL；

问题：

(代码比较多，请耐心看下去)

报错nginx.service不存在

Redirecting to /bin/systemctl start php-fpm.service Failed to start php-fpm.service: Unit not found.

Failed to start php-fpm.service: Unit not found.

Unit php-fpm.service could not be found.

所有这个都提示：php-fpm.service 没有找到。那因为就是因为不存在。于是从网上找到了如下代码：

php-fpm.service:[Unit] Description=The PHP FastCGI Process Manager After=syslog.target network.target [Service] Type=simple PIDFile=/run/php-fpm.pid ExecStart=/usr/local/php7/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf ExecReload=/bin/kill -USR2 $MAINPID ExecStop=/bin/kill -SIGINT $MAINPID [Install] WantedBy=multi-user.target

然后结果还是不对，上面的代码或许放在你们那就是能用的。

报错如下：systemctl status php-fpm.service ● php-fpm.service - The PHP FastCGI Process Manager Loaded: loaded (/usr/lib/systemd/system/php-fpm.service; disabled; vendor pre set: disabled) Active: failed (Result: exit-code) since Tue 2018-06-19 13:28:16 CST; 16s ago Process: 12583 ExecStop=/bin/kill -SIGINT $MAINPID (code=exited, status=1/FAIL URE) Process: 12581 ExecStart=/usr/local/php7/sbin/php-fpm --nodaemonize --fpm-conf ig /usr/local/php7/etc/php-fpm.conf (code=exited, status=203/EXEC) Main PID: 12581 (code=exited, status=203/EXEC) Jun 19 13:28:16 vm10-0-0-19.ksc.com kill[12583]: -q, --queue use ...)

原因：

改正后：[Unit]部分主要是对这个服务的说明，内容包括Description和After，Description用于描述服务，After用于描述服务类别[Unit] Description=php-fpm

我不明白为什么上面的description 改成 php-fpm后，还是不行，以及为甚么php-fpm不可以？希望懂的人，能给我解析一下

关于php-fpm.service 最终的代码内容：[Unit] Description=The PHP FastCGI Process Manager After=syslog.target network.target [Service] Type=simple PIDFile=/run/php-fpm.pid ExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.conf ExecReload=/bin/kill -USR2 $MAINPID ExecStop=/bin/kill -SIGINT $MAINPID [Install] WantedBy=multi-user.target上面改后，然后就是下面的报错。

systemctl status php-fpm.service -l

改过php-fpm.service 后 记得systemctl deamon-restart:然后再开启systemtcl start php-fpm.service

百度别人解决办法：

在/etc/init.d/下添加php-fpm 内容如下：直接复制粘贴到php-fpm下。参考：php-fpm服务启动脚本#! /bin/sh ### BEGIN INIT INFO # Provides: php-fpm # Required-Start: $remote_fs $network # Required-Stop: $remote_fs $network # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: starts php-fpm # Description: starts the PHP FastCGI Process Manager daemon ### END INIT INFO prefix=/usr/local/php exec_prefix=${prefix} php_fpm_BIN=${exec_prefix}/sbin/php-fpm php_fpm_CONF=${prefix}/etc/php-fpm.conf php_fpm_PID=${prefix}/var/run/php-fpm.pid php_opts="--fpm-config $php_fpm_CONF --pid $php_fpm_PID" wait_for_pid () { try=0 while test $try -lt 35 ; do case "$1" in 'created') if [ -f "$2" ] ; then try='' break fi ;; 'removed') if [ ! -f "$2" ] ; then try='' break fi ;; esac echo -n . try=`expr $try + 1` sleep 1 done } case "$1" in start) echo -n "Starting php-fpm " $php_fpm_BIN --daemonize $php_opts if [ "$?" != 0 ] ; then echo " failed" exit 1 fi wait_for_pid created $php_fpm_PID if [ -n "$try" ] ; then echo " failed" exit 1 else echo " done" fi ;; stop) echo -n "Gracefully shutting down php-fpm " if [ ! -r $php_fpm_PID ] ; then echo "warning, no pid file found - php-fpm is not running ?" exit 1 fi kill -QUIT `cat $php_fpm_PID` wait_for_pid removed $php_fpm_PID if [ -n "$try" ] ; then echo " failed.

到这里在重启php-fpm时，杀掉已经占用端口的进程。应该active了。当然很有可能还有其他问题，但是耐下心来，总会解决。

有关MySQL 的安装，待更新
