MySQL master-Slave synchronization configuration

I. Overview

Mysql-ha currently has a lot of implementations, today with the MySQL double master+keepalived to achieve mysql-ha.

in the In the Mysql-ha environment,MySQL is the main slave relationship, which guarantees the consistency of the two MySQL data.

then use keepalived to implement virtual IP, through keepalived to realize the MySQL fault automatically switch.

Second, the experimental environment

virtual machine	operating system	memory/g	HDD/g	note
1	20
Mysql02	192.168.1.101	Ubuntu14.04	1	1	20

third,mysql-server-5.6 installation

The installation process is omitted

Iv. Configuration Mysql Dual Master Architecture

4.1, Create an account for "Replication" on two servers simultaneously

Mysql> GRANT REPLICATION SLAVE, REPLICATION CLIENT on *. * to [e-mail protected] ' 192.168.1.% ' identified by ' 1qaz#edc ';

650) this.width=650; "src=" https://note.youdao.com/yws/res/1198/B696A09769EE457CBD7D92A5F61C1D13 "style=" width : 554px; "alt=" B696a09769ee457cbd7d92a5f61c1d13 "/>

Description: Copy account:copy_user Password:1qaz#edc

Note: You need to create it on two servers, IP Address Please change to the actual IP address

4.2, changing configuration files

4.2.1,mysql01 server Configuration

[Email protected]:~# vim/etc/mysql/my.cnf

What you need to modify is as follows:

bind-address = 0.0.0.0 # is set to 0.0.0.0, allowing any IP connection .

Server-id = 1

Log_bin =/var/log/mysql/mysql-bin.log

Relay_log =/var/log/mysql/mysql-relay-bin

Log_slave_updates = 1

650) this.width=650; "src=" https://note.youdao.com/yws/res/1200/7187AD3EDE134021862B7A11A2E6C918 "style=" width : 477px; "alt=" 7187ad3ede134021862b7a11a2e6c918 "/>

4.2.2,mysql02 server Configuration

[Email protected]:~# vim/etc/mysql/my.cnf

What you need to modify is as follows:

bind-address = 0.0.0.0 # is set to 0.0.0.0, allowing any IP connection .

Server-id = 2

Log_bin =/var/log/mysql/mysql-bin.log

Relay_log =/var/log/mysql/mysql-relay-bin

Log_slave_updates = 1

650) this.width=650; "src=" Https://note.youdao.com/yws/res/1199/08018E78C6CD45E4B1C2231D5E4B6DF3 "style=" width : 504px; "alt=" 08018e78c6cd45e4b1c2231d5e4b6df3 "/>

4.3, two servers to restart MySQL service

/etc/init.d/mysql restart

650) this.width=650; "src=" Https://note.youdao.com/yws/res/1201/240DDDB3D72046FC9343377CDCBB5EFF "style=" width : 554px; "alt=" 240dddb3d72046fc9343377cdcbb5eff "/>

4.4, starting replication on two servers separately

4.4.1,mysql01 configuration

mysql> Change Master to master_host= ' 192.168.1.101 ', master_user= ' copy_user ', master_password= ' 1qaz#edc ';

650) this.width=650; "src=" https://note.youdao.com/yws/res/1195/EA03C23B5E8E4C208339CE017BD75128 "style=" width : 554px; "alt=" ea03c23b5e8e4c208339ce017bd75128 "/>

4.4.2,mysql02 configuration

mysql> Change Master to master_host= ' 192.168.1.100 ', master_user= ' copy_user ', master_password= ' 1qaz#edc ';

650) this.width=650; "src=" Https://note.youdao.com/yws/res/1196/88AEB4C366724A678D6067DD0463F9C9 "style=" width : 554px; "alt=" 88aeb4c366724a678d6067dd0463f9c9 "/>

4.5.1,mysql01 start from replication

mysql> start Slave

4.5.2,mysql02 start from replication

mysql> start Slave

4.6, view status on both servers, yes to indicate configuration success

650) this.width=650; "src=" Https://note.youdao.com/yws/res/1197/E165A5E262DC4C02BB0EC2711D5A3EB7 "style=" width : 554px; "alt=" E165a5e262dc4c02bb0ec2711d5a3eb7 "/>

Now any MySQL data changes, and another database will follow the data update.
