Linux(CentOS)下设置nginx开机自动启动(2个办法)

孤人 提交于 2019-12-26 20:25:06

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

1
vim /etc/init.d/nginx

在脚本中添加如下命令:

复制代码
#!/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

这个脚本来自nginx官方,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。

(注意点:该文件上传至服务器时最好是复制过去,不要用windows写好的文件直接上传,这样会出现不合法提示,无法执行【细看https://blog.csdn.net/russ44/article/details/51694047】)

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

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

下面是另外个脚本:

在脚本中添加如下命令:

复制代码
#!/bin/bash# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
#              It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf

nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/var/run/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.
. /etc/rc.d/init.d/functions
# 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
复制代码

注意配置里的路径,需要将路径改为自己机器的相应路径。

接着,设置文件的访问权限:

chmod a+x /etc/init.d/nginx    ;(a+x参数表示 ==> all user can execute  所有用户可执行)

最后将ngix加入到rc.local文件中,这样开机的时候nginx就默认启动了

vi /etc/rc.local

添加

/etc/init.d/nginx start   

保存并退出

下次重启就会生效,实现nginx的自启动。
