以下教程演示了在centos7.2X64位安装nginx1.10.1,在教程使用前确认一下自己的版本,注意centos7.2上nginx服务启动停止等命名的变化,service nginx start
等命令已经无法使用,注意文章的最后!!!。
一、查看centos版本
[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
二、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
三、 yum 命令去安装 nginx
完成以后,我们就可以使用 yum 命令去安装 nginx 了,像这样:
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!

四、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
成功返回:
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!
五、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
