centos/rhel下實現nginx自啟動指令碼執行個體_linux shell

通常在centos、rhel的OS下，我們大多是通過chkconfig來管理服務，比如開機自動啟動服務之類。
這裡給大家介紹一個很好用的nginx啟動指令碼。以及簡單的使用，如下：

1. 執行如下命令：

vim /etc/init.d/nginxd

2.輸入如下內容：

注意：該檔案中的如下幾個變數，都需要根據你實際的目錄來改寫。

nginx="/usr/local/nginx/sbin/nginx"  ##nginx的可執行檔路徑lockfile="/var/nginx/nginx.lock"   ##需要先建立/var/nginx目錄NGINX_CONF_FILE="/etc/nginx/nginx.conf" ##需要先建立該設定檔#!/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 # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up.

儲存完畢之後，可以執行以下命令來啟動nginx

chmod 777 /etc/init.d/nginxd /etc/init.d/nginxd start

3. 配置開機啟動

執行以下命令：

chkconfig nginxd on

可以以下命令查看是否成功

chkconfig --list | grep nginxd
