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:

  Loaded plugins: fastestmirror, langpacks  nginx                          | 2.9 kB   00:00     nginx/7/x86_64/primary_db                 | 14 kB  00:01     Loading mirror speeds from cached hostfile   * base: mirrors.sina.cn   * extras: mirrors.btte.net   * updates: mirrors.sina.cn  Resolving Dependencies  --> Running transaction check  ---> Package nginx.x86_64 1:1.10.1-1.el7.ngx will be installed  --> Finished Dependency Resolution    Dependencies Resolved    ================================================================================   Package    Arch      Version            Repository   Size  ================================================================================  Installing:   nginx     x86_64     1:1.10.1-1.el7.ngx      nginx     640 k    Transaction Summary  ================================================================================  Install 1 Package    Total download size: 640 k  Installed size: 2.1 M  Is this ok [y/d/N]: y  Downloading packages:  nginx-1.10.1-1.el7.ngx.x86_64.rpm             | 640 kB  00:27     Running transaction check  Running transaction test  Transaction test succeeded  Running transaction   Installing : 1:nginx-1.10.1-1.el7.ngx.x86_64               1/1   ----------------------------------------------------------------------    Thanks for using nginx!

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
