如何进行mysql 5.6不停机双主一从搭建

今天就跟大家聊聊有关如何进行mysql 5.6不停机双主一从搭建，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

环境说明：

版本 version 5.6.25-log 

主1库ip: 10.219.24.25

主2库ip: 10.219.24.22

从1库ip：10.219.24.26

os 版本： centos 6.7

已安装热备软件：xtrabackup 

防火墙已关

mysql 5.6安装 ：http://blog.csdn-/zhang123456456/article/details/53608554

xtrabackup 安装： http://blog.csdn-/zhang123456456/article/details/72836184

整个流程：先搭建一主一从，然后反向搭建双活，最后搭建一主一从

1、 主库参数调整

-- 停止主库mysql

[root@mysql02 ~]# service mysql stop

[root@mysql02 ~]# netstat -nltp|grep mysql|grep 3606

-- 主库创建relay log目录

[root@mysql02 full]# mkdir -p /data/mysql/relaylog/

[root@mysql02 full]# chown -R mysql:mysql /data/mysql/relaylog

-- 调整 my-f 参数

[root@mysql02 ~]# cat /etc/my-f

[root@mysql02 full]# cat /etc/my-f

[client]

password = oracle

port = 3306

socket = /data/mysql/mysql.sock

[mysqld]

server-id=25

port = 3306

socket = /data/mysql/mysql.sock

character_set_server = utf8

character_set_client = utf8

collation-server=utf8_general_ci

lower_case_table_names = 1

max_connections = 1000

datadir = /data/mysql

log_bin = /data/mysql/binarylog/binlog

log_bin_index = /data/mysql/binarylog/binlog

log_slave_updates = 1

relay-log = /data/mysql/relaylog/relay

relay-log-index = /data/mysql/relaylog/relay

relay_log_purge = on

binlog_format = mixed

innodb_data_file_path = ibdata1:12M:autoextend 

auto_increment_increment = 10 

auto_increment_offset = 1

[mysql]

default-character-set = utf8

说明：

a、主库必须配置的参数

server-id （主从的server-id必须不同）、log_bin、binlog_format、relay-log、relay-log-index、relay_log_purge、relay_log_purge

auto-increment-offset、auto-increment-increment

b、log-slave-updates 意思是，中继日志执行之后，这些变化是否需要计入自己的binarylog。 当你的B服务器需要作为另外一个服务器的主服务器的时候需要打开。 就是双主互相备份，或者多主循环备份。 我们这里需要， 所以打开。

c、auto-increment-offset、auto-increment-increment 两个参数用于在 双主（多主循环）互相备份。 因为每台数据库服务器都可能在同一个表中插入数据，如果表有一个自动增长的主键，那么就会在多服务器上出现主键冲突。 解决这个问题的办法就是让每个数据库的自增主键不连续。 上图说是， 我假设需要将来可能需要10台服务器做备份， 所以auto-increment-increment 设为10. 而 auto-increment-offset=1 表示这台服务器的序号。 从1开始， 不超过auto-increment-increment。这样做之后， 我在这台服务器上插入的第一个id就是 1， 第二行的id就是 11了， 而不是2.（同理，在第二台服务器上插入的第一个id就是2， 第二行就是12， 这个后面再介绍） 这样就不会出现主键冲突了。 后面我们会演示这个id的效果。

-- 启动主库

[root@mysql02 ~]# mysqld_safe --defaults-file=/etc/my-f &

2、 从库参数调整

-- 停止从库mysql

[root@mysql01 ~]# service mysql stop

[root@mysql01 ~]# netstat -nltp|grep mysql|grep 3606

-- 调整 my-f 参数

[root@mysql01 ~]# cat /etc/my-f

[client]

password = oracle

port = 3306

socket = /data/mysql/mysql.sock

[mysqld]

server-id=22

port = 3306

socket = /data/mysql/mysql.sock

character_set_server = utf8

character_set_client = utf8

collation-server=utf8_general_ci

lower_case_table_names = 1

max_connections = 1000

datadir = /data/mysql

log_bin = /data/mysql/binarylog/binlog 

log_bin_index = /data/mysql/binarylog/binlog

log_slave_updates = 1

relay-log = /data/mysql/relaylog/relay

relay-log-index = /data/mysql/relaylog/relay

relay_log_purge = on

auto_increment_increment = 10 

auto_increment_offset = 2

[mysql]

default-character-set = utf8

说明：从库必须配置的参数

server-id、log_bin、relay-log、relay_log_purge、auto-increment-offset、auto-increment-increment、relay_log_purge

3、 主库备份

-- 主库备份目录

[root@mysql02 full]# pwd

/xtrabackup/full

-- 主库 innobackupex 备份

[root@mysql02 ~]# innobackupex --user=root --password=oracle --port=3606 /xtrabackup/full/

170610 17:50:23 Backup created in directory /xtrabackup/full/2017-06-10_17-50-19/

MySQL binlog position: filename binlog.000010, position 120

....

170610 17:50:23 completed OK!

-- 查看备份 binlog编号 与 截止 position

[root@mysql02 2017-06-10_17-50-19]# cat xtrabackup_binlog_info

binlog.000010 120

4、 从库创建与主库相同的备份目录

[root@mysql01 ~]# mkdir -p /xtrabackup/full

[root@mysql01 ~]# chown -R mysql:mysql /xtrabackup/full/

5、 主库将备份 scp 到从库

[root@mysql02 full]# pwd

/xtrabackup/full

[root@mysql02 full]# scp -r 2017-06-10_17-50-19 10.219.24.22:/xtrabackup/full

6、 从库查看scp过来的备份

[root@mysql01 ~]# cd /xtrabackup/full/2017-06-10_17-50-19/

[root@mysql01 2017-06-10_17-50-19]# ll

total 12320

-rw-r-----. 1 root root 419 Jun 10 18:01 backup-my-f

-rw-r-----. 1 root root 12582912 Jun 10 18:01 ibdata1

drwxr-x---. 2 root root 4096 Jun 10 18:01 mysql

drwxr-x---. 2 root root 4096 Jun 10 18:01 performance_schema

drwxr-x---. 2 root root 4096 Jun 10 18:01 test

-rw-r-----. 1 root root 18 Jun 10 18:01 xtrabackup_binlog_info

-rw-r-----. 1 root root 113 Jun 10 18:01 xtrabackup_checkpoints

-rw-r-----. 1 root root 482 Jun 10 18:01 xtrabackup_info

-rw-r-----. 1 root root 2560 Jun 10 18:01 xtrabackup_logfile

7、 主库创建同步用户

mysql> GRANT replication slave ON *.* TO slave25@% IDENTIFIED BY oracle; 

Query OK, 0 rows affected (0.05 sec)

8、 从库恢复主库数据

-- 从库将原有datadir文件夹重命名到新位置，并创建原文件夹 

[root@mysql01 ~]# mv /data/mysql /data/mysqlbak

[root@mysql01 ~]# mkdir -p /data/mysql

-- innobackupex apply-log

[root@mysql01 ~]# innobackupex --apply-log --user=oracle \

--password=oracle --port=3606 /xtrabackup/full/2017-06-10_17-50-19/

-- innobackupex copy 恢复的文件到原来的数据位置

[root@mysql01 mysql]# innobackupex --defaults-file=/etc/my-f --user=root \

--copy-back /xtrabackup/full/2017-06-10_17-50-19/

170610 18:25:11 completed OK!

-- 创建binlog目录与 relaylog 目录并赋权

[root@mysql01 ~]# mkdir -p /data/mysql/binarylog

[root@mysql01 ~]# mkdir -p /data/mysql/relaylog/

[root@mysql01 mysql]# chown -R mysql:mysql /data/mysql

9、 从库配置与检测

-- 从库启动

[root@mysql01 mysql]# mysqld_safe --defaults-file=/etc/my-f &

-- 从库指定与主库同步的基本信息
