测试

CentOS 7 构建 LVS-DR 群集 nginx负载均衡,linux,centos,运维
2、配置nginx负载均衡。

132内网服务器

yum localinstall  nginx-1.22.0-1.el7.ngx.x86_64.rpm
[root@localhost ~]# vim /etc/nginx/conf.d/vhost.conf
server {
        listen 80;
        server_name web1.yunjisuan.com;

        location / {
                root /usr/share/nginx/html/web1;
                index index.html index.htm;
        }
        access_log /usr/share/nginx/html/web1/logs/access_bbs.log main;
}
[root@localhost ~]# mkdir -p /usr/share/nginx/html/web1/logs
[root@localhost ~]# echo "`hostname -I `web1" > /usr/share/nginx/html/web1/index.html
[root@localhost ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@localhost ~]# systemctl restart nginx

136内网服务器

yum localinstall  nginx-1.22.0-1.el7.ngx.x86_64.rpm
[root@localhost ~]# vim /etc/nginx/conf.d/vhost.conf
server {
        listen 80;
        server_name web1.yunjisuan.com;

        location / {
                root /usr/share/nginx/html/web1;
                index index.html index.htm;
        }
        access_log /usr/share/nginx/html/web1/logs/access_bbs.log main;
}


[root@localhost ~]# mkdir -p /usr/share/nginx/html/web1/logs
[root@localhost ~]# echo "`hostname -I `web1" > /usr/share/nginx/html/web1/index.html
[root@localhost ~]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@localhost ~]# systemctl restart nginx

137代理服务器

yum localinstall  nginx-1.22.0-1.el7.ngx.x86_64.rpm
[root@localhost ~]# vim /etc/nginx/conf.d/lb_test.conf
upstream www_server_pools {
        server 192.168.231.132:80 weight=1;
        server 192.168.231.136:80 weight=1;
}
server {
        listen 80;
        server_name web1.haha.com;
        location / {
                proxy_pass http://www_server_pools;
                proxy_set_header Host $host;
        }
}
