centos/rhel下实现nginx自启动脚本实例

这篇文章主要介绍了centos/rhel下实现nginx自启动脚本,需要的朋友可以参考下

通常在centos、rhel的OS下，我们大多是通过chkconfig来管理服务，比如开机自动启动服务之类。
这里给大家介绍一个很好用的nginx启动脚本。以及简单的使用，如下：
1. 执行如下命令：
?
1
vim /etc/init.d/nginxd
2.输入如下内容：
注意：该文件中的如下几个变量，都需要根据你实际的目录来改写。

nginx="/usr/local/nginx/sbin/nginx"  ##nginx的可执行文件路径
lockfile="/var/nginx/nginx.lock"   ##需要先创建/var/nginx目录
NGINX_CONF_FILE="/etc/nginx/nginx.conf" ##需要先创建该配置文件
```shell
<div class="md-section-divider"></div>
#!/bin/sh

保存完毕之后，可以执行以下命令来启动nginx
?
1
2
chmod 777 /etc/init.d/nginxd
/etc/init.d/nginxd start
3. 配置开机启动
执行以下命令：
?
1
chkconfig nginxd on
可以以下命令查看是否成功
?
1
chkconfig --list | grep nginxd
