配置NGINX服务
bash
yum安装NGINX
[root@localhost opt]# cd /etc/yum.repos.d
[root@localhost yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo
[root@localhost yum.repos.d]# mkdir repo.bak
[root@localhost yum.repos.d]# mv *.repo repo.bak
[root@localhost yum.repos.d]# ls

完毕!
部署NGINX页面
[root@localhost ~]# cd /usr/share/nginx/html/
[root@localhost html]# ls
50x.html index.html
[root@localhost html]# mkdir mm
[root@localhost html]# cd mm
[root@localhost html]# echo '<h1>this is nginx static web page!</h1>' >test.html
[root@localhost mm]# ls
test.html
实现动静分离
bash
[root@localhost html]# cd /etc/nginx/
[root@localhost nginx]# vim nginx.conf
在 #gzip on;下一行加入
upstream tomcat {
