在Ubuntu上实现LNMP(Linux, Nginx, MySQL/MariaDB, PHP)的高可用性,通常需要考虑负载均衡、故障转移、数据备份和监控等关键因素。以下是一些常见的解决方案:

负载均衡

http {
    upstream backend {
        server backend1.example.com;
        server backend2.example.com;
        server backend3.example.com;
    }

    server {
        listen 80;
        location / {
            proxy_pass http://backend;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
        }
    }
}

故障转移

vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 51
    priority 100
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 42
    }
    virtual_ipaddress {
        192.168.1.100
    }
}

virtual_server 192.168.1.100 80 {
    delay_loop 6
    lb_algo rr
    lb_kind DR
    nat_mask 255.255.255.0
    persistence_timeout 50
    protocol TCP
    real_server 192.168.1.1 80 {
        weight 1
        TCP_CHECK {
            connect_timeout 10
            connect_port 80
        }
    }
    real_server 192.168.1.2 80 {
        weight 1
        TCP_CHECK {
            connect_timeout 10
            connect_port 80
        }
    }
}

数据备份

监控

通过以上步骤,你可以在Ubuntu上实现LNMP的高可用性。请根据你的具体需求和环境进行调整和优化。
