CentOS7操作系统安装nginx实战

1、进入在源目录下，下载nginx官方的repo源

[root@localhost centos]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
Retrieving http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
warning: /var/tmp/rpm-tmp.Sl1gsZ: Header V4 RSA/SHA1 Signature, key ID 7bd9bf62: NOKEY

[root@localhost yum.repos.d]# ll

-rw-r--r--. 1 root root 2523 Dec 13 16:18  CentOS-Base.repo
-rw-r--r--. 1 root root 1309 Oct 23  2020 CentOS-CR.repo
-rw-r--r--. 1 root root  649 Oct 23  2020 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root  314 Oct 23  2020 CentOS-fasttrack.repo
-rw-r--r--. 1 root root  630 Oct 23  2020 CentOS-Media.repo
-rw-r--r--. 1 root root 1331 Oct 23  2020 CentOS-Sources.repo
-rw-r--r--. 1 root root 8515 Oct 23  2020 CentOS-Vault.repo
-rw-r--r--. 1 root root  616 Oct 23  2020 CentOS-x86_64-kernel.repo
-rw-r--r--. 1 root root  113 Jul 15  2014 nginx.repo
[root@localhost yum.repos.d]#

此时目录下会多一个文件： CentOS-Base.repo

2、安装Nginx

yum install nginx -y

[root@localhost yum.repos.d]# nginx -v
nginx version: nginx/1.24.0

默认是最新版本的

3、启动，设置开机自启动

[root@localhost yum.repos.d]# nginx
[root@localhost yum.repos.d]# systemctl enable nginx
[root@localhost yum.repos.d]# systemctl status nginx
