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:
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;
}
}
}
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
}
}
}
mysqldump
命令备份MySQL数据库,使用 cp
命令备份Nginx配置文件。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。
