下文內(nèi)容主要給大家?guī)?lái)MySQL雙主高可用配置方法解析，這里所講到的知識(shí)，與書(shū)籍略有不同，都是創(chuàng)新互聯(lián)專業(yè)技術(shù)人員在與用戶接觸過(guò)程中，總結(jié)出來(lái)的，具有一定的經(jīng)驗(yàn)分享價(jià)值，希望給廣大讀者帶來(lái)幫助。 

創(chuàng)新互聯(lián)專注為客戶提供全方位的互聯(lián)網(wǎng)綜合服務(wù)，包含不限于成都網(wǎng)站制作、網(wǎng)站設(shè)計(jì)、外貿(mào)網(wǎng)站建設(shè)、來(lái)鳳網(wǎng)絡(luò)推廣、微信小程序開(kāi)發(fā)、來(lái)鳳網(wǎng)絡(luò)營(yíng)銷、來(lái)鳳企業(yè)策劃、來(lái)鳳品牌公關(guān)、搜索引擎seo、人物專訪、企業(yè)宣傳片、企業(yè)代運(yùn)營(yíng)等，從售前售中售后，我們都將竭誠(chéng)為您服務(wù)，您的肯定，是我們最大的嘉獎(jiǎng)；創(chuàng)新互聯(lián)為所有大學(xué)生創(chuàng)業(yè)者提供來(lái)鳳建站搭建服務(wù)，24小時(shí)服務(wù)熱線：18982081108，官方網(wǎng)址：aaarwkj.com

一、在兩臺(tái)云服務(wù)器上分別安裝MySQL實(shí)例

Mysql01:192.168.0.207

Mysql02:192.168.0.208

vip1:192.168.0.211

vip2:192.168.0.212

(略)

二、在兩臺(tái)服務(wù)器上配置主主復(fù)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,這個(gè)方案的關(guān)鍵點(diǎn)在于keepalived的配制，兩個(gè)vrrp_instance在兩個(gè)主上的優(yōu)先級(jí)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

}

}
