Linux环境下安装Nginx及其使用

https://www.jb51.net/article/136161.htm

一、查看CentOS的版本

?

1	cat /etc/redhat-release

二、添加资源库

在 CentOS 系统上安装 Nginx ，得先去添加一个资源库：

?

1 2 3 4 5 6

vim /etc/yum.repos.d/nginx.repo   [nginx]   name=nginx repo   baseurl=http://nginx.org/packages/centos/$releasever/$basearch/   gpgcheck=0   enabled=1

三、安装nginx

?

1	yum -y install nginx

四、测试nginx配置文件是否正确

?

1

nginx -t

打印如下：

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

五、CentOS7.0+ nginx实现停止、启动、重启

?

1 2 3 4

systemctl stop nginx.service  systemctl start nginx.service systemctl restart nginx.service systemctl status nginx.service

开机自启：

?

1	systemctl enable nginx.service

取消开机自启：

?

1	systemctl disable nginx.service

六、nginx.conf配置示例
