環境

1， CentOS 8
2， nginx 1.18.0

步驟

1，先安裝 yum-utils

shell> yum install yum-utils

2，添加nginx源。創建文件/etc/yum.repos.d/nginx.repo，文件內容如下：

[nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true[nginx-mainline] name=nginx mainline repo baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/ gpgcheck=1 enabled=0 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true

3，查看nginx源

shell> yum info nginx CentOS-8 - AppStream 67 kB/s | 4.3 kB 00:00 CentOS-8 - Base 56 kB/s | 3.9 kB 00:00 CentOS-8 - Extras 17 kB/s | 1.5 kB 00:00 Extra Packages for Enterprise Linux 8 - x86_64 60 kB/s | 4.7 kB 00:00 nginx stable repo 350 B/s | 2.9 kB 00:08 nginx mainline repo 2.1 kB/s | 2.9 kB 00:01 Installed Packages Name : nginx Epoch : 1 Version : 1.18.0 Release : 1.el8.ngx Architecture : x86_64 Size : 3.6 M Source : nginx-1.18.0-1.el8.ngx.src.rpm Repository : @System From repo : nginx-stable Summary : High performance web server URL : http://nginx.org/ License : 2-clause BSD-like license Description : nginx [engine x] is an HTTP and reverse proxy server, as well as: a mail proxy server.

4，安裝nginx

shell> yum install nginx CentOS-8 - AppStream 62 kB/s | 4.3 kB 00:00 CentOS-8 - Base 55 kB/s | 3.9 kB 00:00 CentOS-8 - Extras 18 kB/s | 1.5 kB 00:00 Extra Packages for Enterprise Linux 8 - x86_64 48 kB/s | 4.7 kB 00:00 nginx stable repo 986 B/s | 2.9 kB 00:03 nginx mainline repo 1.6 kB/s | 2.9 kB 00:01 Dependencies resolved. ================================================================================Package Architecture Version Repository Size ================================================================================ Installing:nginx x86_64 1:1.18.0-1.el8.ngx nginx-stable 806 kTransaction Summary ================================================================================ Install 1 PackageTotal download size: 806 k Installed size: 3.6 M Is this ok [y/N]: y Downloading Packages: nginx-1.18.0-1.el8.ngx.x86_64.rpm 5.7 kB/s | 806 kB 02:20 -------------------------------------------------------------------------------- Total 5.7 kB/s | 806 kB 02:20 warning: /var/cache/dnf/nginx-stable-614ef03fac352fea/packages/nginx-1.18.0-1.el8.ngx.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID 7bd9bf62: NOKEY nginx stable repo 511 B/s | 1.5 kB 00:03 Importing GPG key 0x7BD9BF62:Userid : "nginx signing key <signing-key@nginx.com>"Fingerprint: 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62From : https://nginx.org/keys/nginx_signing.key Is this ok [y/N]: y Key imported successfully Running transaction check Transaction check succeeded.

5，啟動nginx

systemctl start nginx

6，查看nginx是否啟動

shell> systemctl status nginx ● nginx.service - nginx - high performance web serverLoaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor pres>Active: active (running) since Sat 2020-05-02 00:08:53 CST; 1s agoDocs: http://nginx.org/en/docs/Process: 25856 ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf (code=exite>Main PID: 25857 (nginx)Tasks: 2 (limit: 5063)Memory: 2.1MCGroup: /system.slice/nginx.service├─25857 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.co>└─25858 nginx: worker processMay 02 00:08:53 iZm5e97k4o3byiq752mii6Z systemd[1]: Starting nginx - high perfo> May 02 00:08:53 iZm5e97k4o3byiq752mii6Z systemd[1]: nginx.service: Can't open P> May 02 00:08:53 iZm5e97k4o3byiq752mii6Z systemd[1]: Started nginx - high perfor> lines 1-15/15 (END)

或者

shell> ps -ef | grep nginx root 25857 1 0 00:08 ? 00:00:00 nginx: master process /usr/sbin nginx -c /etc/nginx/nginx.conf nginx 25858 25857 0 00:08 ? 00:00:00 nginx: worker process root 25863 25101 0 00:09 pts/2 00:00:00 grep --color=auto nginx

7，查看80端口返回的內容

curl localhost:80

其它

也可以手工配置nginx官方yum源，這樣更靈活一些。配制方法參考官方說明：http://nginx.org/en/linux_packages.html
