一. 为Nginx设置yum仓库
1. 创建文件/etc/yum.repos.d/nginx.repo，写入以下内容：
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
二. 使用yum安装Nginx
1. 安装Nginx
[root@localhost yum.repos.d]# yum install nginx
Loaded plugins: fastestmirror, langpacks
nginx | 2.9 kB 00:00:05
nginx/x86_64/primary_db FAILED ========= ] 6.8 B/s | 22 kB 00:05:40 ETA

三. 将Nginx服务加入系统自启动
1. cd到/lib/systemd/system/目录
[root@localhost system]# cd /lib/systemd/system
2. 查看nginx.service文件
[root@localhost system]# ls -l nginx*
-rw-r--r--. 1 root root 445 Apr 12 11:23 nginx-debug.service
-rw-r--r--. 1 root root 454 Apr 12 11:23 nginx.service 3. 使用yum安装Nginx，都会自动生成nginx.service，更改文件的权限
[root@localhost system]# chmod 745 nginx.service
[root@localhost system]# !ls
ls -l nginx*
-rw-r--r--. 1 root root 445 Apr 12 11:23 nginx-debug.service
-rwxr--r-x. 1 root root 454 Apr 12 11:23 nginx.service
4. 使用systemctl命令设置开机启动Nginx服务
[root@localhost system]# systemctl enable nginx.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@localhost system]#
