nginx 開機自動啟動

接下來聊一聊nginx的開機自啟吧

看了看都是用腳本啟動的，我也就不扯啥犢子了，都是前人經驗

我的操作系統是centos 7 nginx版本是1.10.3

首先看一下自己的nginx配置

我的是

./configure \

--prefix=/usr/local/nginx \

--pid-path=/usr/local/nginx/logs/nginx.pid \

--lock-path=/var/lock/nginx.lock \

--error-log-path=/var/log/nginx/error.log \

--http-log-path=/var/log/nginx/access.log \

--with-http_gzip_static_module \

--http-clicent-body-temp-path=/var/temp/nginx/client \

--http-proxy-temp-path=/var/temp/nginx/proxy \

--http-fastcgi-temp-path=/var/temp/nginx/fastcgi \

--http-uwsgi-temp-path=/var/temp/nginx/uwsgi \

--http-scgi-temp-path=/var/temp/nginx/scgi \

這些路徑下面腳本文件中用的到

 

 

編寫腳本 ：vim /etc/init.d/nginx

內容：

#!/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: /usr/local/nginx/logs/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=/usr/local/nginx/logs/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 /usr/local/nginx/logs/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

對於shell腳本中的部分路徑請改成你主機上的nginx的相應路徑

接下來更改這個腳本的訪問權限：chmod a+x /etc/init.d/nginx

這樣在控制台就很容易的操作nginx了：nginx {start|reload|stop|status}

如果修改了nginx的配置文件nginx.conf，也可以使用上面的命令重新加載新的配置文件並運行，可以將此命令加入到rc.local文件中，這樣開機的時候nginx就默認啟動了

編輯rc.local文件：vi /etc/rc.local 

加入 /etc/init.d/nginx start  保存退出

下次重啟會生效

如果重啟后發現並沒有生效，原因是rc.local這個文件沒有執行 那我們修改一下rc.local的權限

chmod +x /etc/rc.d/rc.local

這樣就可以了      就先這樣吧
