Nginx和PHP-FPM的启动/重启脚本

这段时间在捣鼓服务器，Nginx和PHP都是源码编译安装的，每次都得打上长长的路径才能启动，或者在/etc/rc.local里写，启动的时候又看不到确定提示，所以不支持类似以前的nginx (start|restart|stop|reload)了。所以在网上找了这个脚本并且测试正常，在这里记录一下。博客有2个月没更新了，这算是2012年第一篇吧，哈哈，情人节快乐。

一、Nginx启动脚本/etc/init.d/nginx

#!/bin/bash
#
#Startup script for Nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /usr/local/nginx/conf/nginx.conf
# pidfile:     /usr/local/nginx/logs/nginx.pid

# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx

start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}

stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}

restart() {
    configtest || return $?
    stop
    sleep 1
    start
}

reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}

force_reload() {
    restart
}

configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}

rh_status() {
    status $prog
}

rh_status_q() {
    rh_status >/dev/null 2>&1
}

case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

编辑好后保存，执行以下命令

chmod +x /etc/init.d/nginx

现在把Nginx加入chkconfig，并设置开机启动。

chkconfig --add nginx
chkconfig nginx on

# 检查一下

chkconfig --list nginx

nginx 0:off 1:off 2:on 3:on 4:on 5:on 6:off

启动、停止、查看状态的命令如下:

service nginx start
service nginx stop
service nginx restart
service nginx reload

/etc/init.d/nginx start
/etc/init.d/nginx stop
/etc/init.d/nginx restart
/etc/init.d/nginx reload

systemctl 脚本

cat /lib/systemd/system/nginx.service
[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/run/nginx.pid
ExecStartPre=/data/app/nginx/sbin/nginx -t -c /data/app/nginx/conf/nginx.conf
ExecStart=/data/app/nginx/sbin/nginx -c /data/app/nginx/conf/nginx.conf
ExecReload=/data/app/nginx/sbin/nginx -s reload
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true


[Install]
WantedBy=multi-user.target



systemctl enable nginx.service


现在可以使用下面的指令来控制nginx啦
systemctl start nginx.service
systemctl reload nginx.service
systemctl restart nginx.service
systemctl stop nginx.service

#日志
$ journalctl -f -u nginx.service

#下面这几个路径是你的nginx安装的目录，务必不要弄错。 
PIDFile=/run/nginx.pid
ExecStartPre=/usr/sbin/nginx -t -c /etc/nginx/nginx.conf
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf

二、PHP-FPM启动脚本/etc/init.d/php-fpm

从PHP 5.3.3开始就已经集成了PHP-FPM所以php-fpm在PHP 5.3.2以后的版本不支持以前的php-fpm (start|restart|stop|reload) 了，不用专门再打补丁了，只需要解开源码直接configure，关于php-fpm的编译参数有

--enable-fpm --with-fpm-user=www --with-fpm-group=www --with-libevent-dir=libevent位置

进入到php源代码目录下，然后：

cp -f (php -5.3.x-source-dir)/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm

#! /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"

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 $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. Use force-quit"
			exit 1
		else
			echo " done"
		fi
	;;

	force-quit)
		echo -n "Terminating php-fpm "

		if [ ! -r $php_fpm_PID ] ; then
			echo "warning, no pid file found - php-fpm is not running ?"
			exit 1
		fi

		kill -TERM `cat $php_fpm_PID`

		wait_for_pid removed $php_fpm_PID

		if [ -n "$try" ] ; then
			echo " failed"
			exit 1
		else
			echo " done"
		fi
	;;

	restart)
		$0 stop
		$0 start
	;;

	reload)

		echo -n "Reload service php-fpm "

		if [ ! -r $php_fpm_PID ] ; then
			echo "warning, no pid file found - php-fpm is not running ?"
			exit 1
		fi

		kill -USR2 `cat $php_fpm_PID`

		echo " done"
	;;

	*)
		echo "Usage: $0 {start|stop|force-quit|restart|reload}"
		exit 1
	;;

esac

编辑好后保存，执行以下命令

chmod +x /etc/init.d/php-fpm
chkconfig php-fpm on
# 检查一下
chkconfig --list php-fpm
php-fpm 0:off 1:off 2:on 3:on 4:on 5:on 6:off

完成！可以使用以下命令管理php-fpm了

service php-fpm start
service php-fpm stop
service php-fpm restart
service php-fpm reload

/etc/init.d/php-fpm start
/etc/init.d/php-fpm stop
/etc/init.d/php-fpm restart
/etc/init.d/php-fpm reload

运行service php-fpm start提示出错，怎么都没找到问题所在，后来才知道要把php-fpm.conf里的PID路径前的:分号删掉！如图：

才知道前面的分号是注释符，像#号一样。
