CentOS 7.2 安装Nginx

首先查询CentOS版本 

[root@VM_0_7_centos ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core) 

添加资源库

vim /etc/yum.repos.d/nginx.repo

使用 vim 命令去打开 /etc/yum.repos.d/nginx.repo ，如果 nginx.repo 不存在，会自动创建，打开以后按 i 键，进入编辑模式，复制如下代码，完成以后按 esc 键退出，再输入:wq （保存并退出）

[nginx]

name=nginx repo

baseurl=http://nginx.org/packages/centos/$releasever/$basearch/

gpgcheck=0

enabled=1

yum 命令去安装 nginx

使用yum命令安装输入如下命令：

yum install nginx

安装成功：

测试nginx配置文件

当你执行 nginx -t    nginx会去测试你得配置文件得语法，并告诉你配置文件是否写得正确，同时也告诉了你配置文件得路径：

[root@VM_0_7_centos ~]# nginx -t 
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
为配置成功

centos7.0+ nginx实现停止、启动、重启

在CentOS7中，进行chkconfig命令操作时会发现有类似“systemctl.....”的提示，systemctl可以简单实现service和chkconfig的结合，这样通过一个命令就可以实现两个命令的功能。

systemctl命令的基本操作格式是：

 

systemctl [OPTIONS...] {COMMAND}...

 

以nginx服务为例，实现停止、启动、重启的动作如下：

 

systemctl stop  nginx.service

 

systemctl start  nginx.service

 

systemctl restart nginx.service

 

 

检查服务状态

 

systemctl status nginx.service

 

使服务开机启动

 

systemctl enable nginx.service

 

取消服务开机启动

 

systemctl disable nginx.service

 

 

路径整理

# nginx 配置文件

/etc/nginx/nginx.conf

 

# nginx 默认项目路径

/usr/share/nginx/html
