Linux(CentOS)下设置nginx开机自动启动和chkconfig管理

Nginx 是一个很强大的高性能Web和反向代理服务器。虽然使用命令行可以对nginx进行各种操作,比如启动等,但是还是根据不太方便。下面介绍在Linux下安装后,如何设置开机自启动。

首先,在linux系统的/etc/init.d/目录下创建nginx文件,使用如下命令:

vim /etc/init.d/nginx

 

在脚本中添加如下命令:

#!/bin/sh
#
# 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:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
   # make required directories
   user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
   if [ -z "`grep $user /etc/passwd`" ]; then
       useradd -M -s /bin/nologin $user
   fi
   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}
start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    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

 

这个脚本其实也不是我写的,谁写的呢,nginx官方写的,脚本地址:http://wiki.nginx.org/RedHatNginxInitScript ,不过要注意,如果你是自定义编译安装的nginx,需要根据您的安装路径修改下面这两项配置:

nginx=”/usr/sbin/nginx” 修改成nginx执行程序的路径。

NGINX_CONF_FILE=”/etc/nginx/nginx.conf” 修改成配置文件的路径。

保存脚本文件后设置文件的执行权限:

chmod a+x /etc/init.d/nginx

然后,就可以通过该脚本对nginx服务进行管理了:

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

注意:一定要注意nginx的编码格式。不然会出现以下错误:

[root@iZ2ze7dyjfik9i0bgl5o1cZ bin]# /etc/init.d/nginx start
-bash: /etc/init.d/nginx: /bin/sh^M: bad interpreter: No such file or directory

解决方法

首先要确保文件有可执行权限:
cd /etc/init.d/
chmod a+x nginx


然后修改文件格式:
vim nginx

利用如下命令查看文件格式 
:set ff 或 :set fileformat

可以看到如下信息 
fileformat=dos 或 fileformat=unix 

利用如下命令修改文件格式 
:set ff=unix 或 :set fileformat=unix

:wq (存盘退出)

 

使用chkconfig进行管理

上面的方法完成了用脚本管理nginx服务的功能,但是还是不太方便,比如要设置nginx开机启动等。这时可以使用chkconfig来设置。

先将nginx服务加入chkconfig管理列表:

chkconfig --add /etc/init.d/nginx

 

加完这个之后,就可以使用service对nginx进行启动,重启等操作了。

service nginx start
service nginx stop

 

设置终端模式开机启动:

chkconfig nginx on

 

chkconfig命令的使用方法,就不多数啦,可以自行搜索



另外这里还有一个网友分享的脚本(脚本地址:http://blog.163.com/qsc0624@126/blog/static/140324073201312734548701/):

#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15

# processname: nginx

# config: /usr/local/nginx/conf/nginx.conf
nginxd=/usr/local/nginx/sbin/nginx

nginx_pid=/var/run/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.

# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
   echo "nginx already running...."
   exit 1
fi
   echo -n $"Starting $prog: "
   daemon $nginxd -c ${nginx_config}
   RETVAL=$?
   echo
   [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
   return $RETVAL
}
# Stop nginx daemons functions.
stop() {
        echo -n $"Stopping $prog: "
        killproc $nginxd
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid
}
# reload nginx service functions.
reload() {
    echo -n $"Reloading $prog: "
    #kill -HUP `cat ${nginx_pid}`
    killproc $nginxd -HUP
    RETVAL=$?
    echo
}
# See how we were called.
case "$1" in
start)
        start
        ;;
stop)
        stop
        ;;
reload)
        reload
        ;;
restart)
        stop
        start
        ;;
status)
        status $prog
        RETVAL=$?
        ;;
*)
        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL

 

使用此脚本的时候,也同样需要将配置路径修改成自己的
