下文内容主要给大家带来MySQL双主高可用配置方法解析，这里所讲到的知识，与书籍略有不同，都是创新互联专业技术人员在与用户接触过程中，总结出来的，具有一定的经验分享价值，希望给广大读者带来帮助。
创新互联公司专注于企业营销型网站、网站重做改版、隆德网站定制设计、自适应品牌网站建设、HTML5、成都商城网站开发、集团公司官网建设、成都外贸网站建设、高端网站制作、响应式网页设计等建站业务，价格优惠性价比高，为隆德等各大城市提供网站开发制作服务。一、在两台云服务器上分别安装MySQL实例
Mysql01:192.168.0.207
Mysql02:192.168.0.208
vip1:192.168.0.211
vip2:192.168.0.212
(略)
二、在两台服务器上配置主主复制
GRANT REPLICATION SLAVE ON *.* TO 'dba_repl'@'192.168.0.%' IDENTIFIED BY '123456';
change master to MASTER_HOST='192.168.0.207',
MASTER_USER='dba_repl',
MASTER_PASSWORD ='123456',
MASTER_LOG_FILE = 'mysql-bin.000003',
MASTER_LOG_POS = 120
;
三、配置keepalived,这个方案的关键点在于keepalived的配制，两个vrrp_instance在两个主上的优先级相反。
MySQL01：
global_defs {
# Keepalived process identifier
lvs_id MySQL_HA
}
# Script used to check if Proxy is running
vrrp_script check_proxy {
script "killall -0 mysql"
interval 2
weight 3
}
# Virtual interface 1
# The priority specifies the order in which the assigned interface to take over in a failover
vrrp_instance VI_01 {
state MASTER
interface eth0
virtual_router_id 51
priority 100
# The virtual ip address shared between the two loadbalancers
virtual_ipaddress {
192.168.0.211 dev eth0
}
track_script {
check_proxy
}
}
# Virtual interface 2
# The priority specifies the order in which the assigned interface to take over in a failover
vrrp_instance VI_02 {
state MASTER
interface eth0
virtual_router_id 52
priority 102
# The virtual ip address shared between the two loadbalancers
virtual_ipaddress {
192.168.0.212 dev eth0
}
track_script {
check_proxy
}
}
主二：
global_defs {
# Keepalived process identifier
lvs_id MySQL_HA
}
# Script used to check if Proxy is running
vrrp_script check_proxy {
script "killall -0 mysql"
interval 2
weight 3
}
# Virtual interface 1
# The priority specifies the order in which the assigned interface to take over in a failover
vrrp_instance VI_01 {
state MASTER
interface eth0
virtual_router_id 51
priority 102
# The virtual ip address shared between the two loadbalancers
virtual_ipaddress {
10.103.9.211 dev eth0
}
track_script {
check_proxy
}
}
# Virtual interface 2
# The priority specifies the order in which the assigned interface to take over in a failover
vrrp_instance VI_02 {
state MASTER
interface eth0
virtual_router_id 52
priority 100
# The virtual ip address shared between the two loadbalancers
virtual_ipaddress {
192.168.0.212 dev eth0
}
track_script {
check_proxy
}
}
