Linux(CentOS)下設置nginx開機自動啓動（2個辦法）

首先，在linux系統的/etc/init.d/目錄下建立nginx文件，使用以下命令：

vim /etc/init.d/nginx

在腳本中添加以下命令：

#!/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

這個腳原本自nginx官方，腳本地址：http://wiki.nginx.org/RedHatNginxInitScript ，不過要注意，若是你是自定義編譯安裝的nginx，須要根據您的安裝路徑修改下面這兩項配置：

nginx=」/usr/sbin/nginx」 修改爲nginx執行程序的路徑。

NGINX_CONF_FILE=」/etc/nginx/nginx.conf」 修改爲配置文件的路徑。

保存腳本文件後設置文件的執行權限：

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

而後，就能夠經過該腳本對nginx服務進行管理了：

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

使用chkconfig進行管理

上面的方法完成了用腳本管理nginx服務的功能，可是仍是不太方便，好比要設置nginx開機啓動等。這時可使用chkconfig來設置。

先將nginx服務加入chkconfig管理列表：

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

加完這個以後，就可使用service對nginx進行啓動，重啓等操做了。

service nginx start
service nginx stop

設置終端模式開機啓動：

chkconfig nginx on

==============================================================

下面是另外個腳本：

在腳本中添加以下命令：

#!/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

注意配置裏的路徑，須要將路徑改成本身機器的相應路徑。

接着，設置文件的訪問權限：

chmod a+x /etc/init.d/nginx    ;(a+x參數表示 ==> all user can execute  全部用戶可執行)

最後將ngix加入到rc.local文件中，這樣開機的時候nginx就默認啓動了

vi /etc/rc.local

添加

/etc/init.d/nginx start   

保存並退出

下次重啓就會生效，實現nginx的自啓動。
