Nginx和PHP-FPM的启动/重启脚本

一，Nginx的启动脚本/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的加入chkconfig的，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

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（开始|重启|停止|重新加载）了，不用专门再打补丁了，只需要解开源码直接配置，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

### 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

运行服务php-fpm start提示出错，要把php-fpm.conf里的PID路径前的：分号删掉！如图：
