一、配置负载均衡

配置麒麟的yum源

vim /etc/yum.repos.d/kylin_aarch64.repo

Copy

删除原来内容，写入如下yum源

[ks10-adv-os]
name = Kylin Linux Advanced Server 10 - Os
baseurl = http://update.cs2c.com.cn:8080/NS/V10/V10SP2/os/adv/lic/base/aarch64/
gpgcheck = 0
enabled = 1
[ks10-adv-updates]
name = Kylin Linux Advanced Server 10 - Updates
baseurl = http://update.cs2c.com.cn:8080/NS/V10/V10SP2/os/adv/lic/updates/aarch64/
gpgcheck = 0
enabled = 1

Copy

同步源

yum repolist

Copy

安装并运行nginx

yum install -y nginx
systemctl start nginx.service
systemctl status nginx.service

Copy

防火墙放行对应端口入站流量（案例中直接关闭防火墙）

systemctl stop firewalld.service
systemctl status firewalld.service

Copy

cd /etc/nginx/conf.d/
vim lb.conf

Copy

lb.conf的内容

upstream lb {
server 127.0.0.1:8085 weight=1;
server 127.0.0.1:8086 weight=2;
}

server {
listen 8085;
return 200 "node1\r\n";
}

server {
listen 8086;
return 200 "node2\r\n";
}

server {
listen 8080;

location / {
proxy_pass http://lb;
proxy_connect_timeout 10s;
proxy_read_timeout 5s;
proxy_send_timeout 5s;
}
}

Copy

 保存退出，使lb.conf生效

nginx -s reload

Copy

二、测试访问

curl http://127.0.0.1:8080
curl http://127.0.0.1:8080
curl http://127.0.0.1:8080

Copy

三、配置四层反向代理

查看IP地址

ifconfig enp0s2

Copy

将sgtream模块如下代码插入nginx主配置文件

vim /etc/nginx/nginx.conf

Copy

在nginx.conf的末尾加上以下内容

stream {
        upstream ssh {
                server IP地址:22;
        }

        server {
                listen 10022;
                proxy_pass ssh;
                proxy_connect_timeout 10;
        }
}

Copy

保存退出，使文件生效

nginx -s reload

Copy

查看结果

telnet 127.0.0.1 10022

Copy
