CentOS7.2安装Nginx的方法步骤
CentOS7.2安装Nginx过程笔记,由于学习的需要,这段时间学一点“nginx”。今天学习一下Nginx安装,留个笔记
查看CentOS的版本
使用一下命令来查看一下当前系统的版本
[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
添加资源库
在 CentOS 系统上安装 Nginx ,你得先去添加一个资源库,像这样:
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,就会去创建一个这样的文件,打开以后按一下小 i 键,进入编辑模式,然后复制粘贴下面这几行代码,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
完成上边操作以后,我们就可以使用 yum 命令去安装 nginx 了
yum install nginx
安装成功:

测试nginx配置文件
当你执行 nginx -t 得时候,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:
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
说明配置文件成功!
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
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
