1、架构说明
| 主机 | IP | 作用 |
| node10 | 192.168.1.209 | MySQL主机 |
| node09 | 192.168.1.208 | MySQL从机 |
| node08 | 192.168.1.207 | MySQL从机 |
| node06 | 192.168.1.205 | Fabric主机，MySQL 5.7 |
注：node10\node09\node08的主从已经配置过程略过
2、下载工具包
mkdir soft cd soft wget http://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-2.1.3-1.el6.x86_64.rpm wget http://dev.mysql.com/get/Downloads/MySQLGUITools/mysql-utilities-1.5.6-1.el6.noarch.rpm wget http://downloads.mysql.com/archives/get/file/mysql-5.7.9-1.el6.x86_64.rpm-bundle.tar tar -xvf mysql-5.7.9-1.el6.x86_64.rpm-bundle.tar
3、安装Fabric工具包
[root@node06 soft]# rpm -ivh mysql-connector-python-2.1.3-1.el6.x86_64.rpm warning: mysql-connector-python-2.1.3-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql-connector-python ########################################### [100%] [root@node06 soft]# rpm -ivh mysql-utilities-1.5.6-1.el6.noarch.rpm warning: mysql-utilities-1.5.6-1.el6.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ########################################### [100%] 1:mysql-utilities ########################################### [100%]
4、安装MySQL
[root@node06 soft]# rpm -qa|grep mysql |xargs -i rpm -e --nodeps {};
[root@node06 soft]# rpm -ivh mysql-community-*
warning: mysql-community-client-5.7.9-1.el6.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

创建数据目录 mkdir -p /u01/mysql 修改配置文件 vi /etc/my.cnf [mysqld] datadir=/u01/mysql socket=/var/lib/mysql/mysql.sock symbolic-links=0 log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid 初始化库 mysqld --initialize --datadir=/u01/mysql 启动数据库 service mysqld restart Stopping mysqld: [ OK ] Initializing MySQL database: [ OK ] Starting mysqld: [ OK ] 查看密码 [root@node06 soft]# cat /var/log/mysqld.log |grep root 2016-03-15T14:54:17.104028Z 1 [Note] A temporary password is generated for root@localhost: %FoohqpBe5UK 登陆数据库修改密码 mysql -uroot -p‘%FoohqpBe5UK‘ mysql> set password=password(‘Fabric123*‘); 创建帐号及数据库 [root@node06 soft]# mysql -uroot -p‘Fabric123*‘ mysql> create database fabric; mysql> grant all on fabric.* to fabric@‘%‘ identified by ‘Fabricdb123*‘; mysql> grant all on fabric.* to fabric@‘localhost‘ identified by ‘Fabricdb123*‘; mysql> drop database fabric;
6、修改Fabric配置文件
vi /etc/mysql/fabric.cfg ..... [storage] auth_plugin = mysql_native_password database = fabric user = fabric address = localhost:3306 connection_delay = 1 connection_timeout = 6 password = Fabricdb123* .....
7、初始化库
[root@node06 soft]# mysqlfabric manage setup --param=storage.user=fabric [INFO] 1458056916.001109 - MainThread - Initializing persister: user (fabric), server (localhost:3306), database (fabric). Finishing initial setup ======================= Password for admin user is not yet set. Password for admin/xmlrpc: Repeat Password: Password set. Password set.
8、查询数据库
[root@node06 soft]# mysql -uroot -p‘Fabric123*‘ mysql> use fabric;show tables; Database changed +-------------------+ | Tables_in_fabric | +-------------------+ | checkpoints | | error_log | | group_replication | | group_view | | groups | | log | | machines | | permissions | | proc_view | | providers | | role_permissions | | roles | | servers | | shard_maps | | shard_ranges | | shard_tables | | shards | | user_roles | | users | +-------------------+ 19 rows in set (0.00 sec)
9、启动FABRIC
[root@node06 soft]# mysqlfabric manage start & [1] 2711 [root@node06 mysql]# [INFO] 1458060656.261079 - MainThread - Initializing persister: user (fabric), server (192.168.1.205:3306), database (fabric).

10、创建成员组
[root@node06 soft]# mysqlfabric group create mydb_group Fabric UUID: 5ca1ab1e-a007-feed-f00d-cab3fe13249e Time-To-Live: 1 uuid finished success result ------------------------------------ -------- ------- ------ 8a41bc19-dc88-465c-84ad-4ef0c534193f 1 1 1 state success when description ----- ------- ------------- ------------------------------------------------------------- 3 2 1.45806e+09 Triggered by <mysql.fabric.events.Event object at 0x195ad90>. 4 2 1.45806e+09 Executing action (_create_group). 5 2 1.45806e+09 Executed action (_create_group).
11、创建Fabric管理帐号到各数据库上
[root@node10 ~]# mysql -uroot -p123456 -e "grant all on *.* to fabric@‘192.168.1.%‘ identified by ‘Server*01‘"
[root@node09 ~]# mysql -uroot -p123456 -e "grant all on *.* to fabric@‘192.168.1.%‘ identified by ‘Server*01‘"
[root@node08 ~]# mysql -uroot -p123456 -e "grant all on *.* to fabric@‘192.168.1.%‘ identified by ‘Server*01‘"
12、添加成员
mysqlfabric group add mydb_group 192.168.1.209:13306 mysqlfabric group add mydb_group 192.168.1.208:13306 mysqlfabric group add mydb_group 192.168.1.207:13306
13、查看成员组信息
[root@node06 soft]# mysqlfabric group lookup_servers mydb_group Fabric UUID: 5ca1ab1e-a007-feed-f00d-cab3fe13249e Time-To-Live: 1 server_uuid address status mode weight ------------------------------------ ------------------- --------- --------- ------ 19e625e0-ea04-11e5-b192-0800273bba44 192.168.1.208:13306 SECONDARY READ_ONLY 1.0 5592ca61-ae26-11e5-8586-08002732e007 192.168.1.209:13306 SECONDARY READ_ONLY 1.0 7cb26cac-ea9d-11e5-a9a1-080027d9fe9c 192.168.1.207:13306 SECONDARY READ_ONLY 1.0
14、自动选主
[root@node06 soft]# mysqlfabric group promote mydb_group [INFO] 1458061339.876909 - Executor-0 - Master has changed from 7cb26cac-ea9d-11e5-a9a1-080027d9fe9c to None.

15、查看信息
[root@node06 soft]# mysqlfabric group lookup_servers mydb_group Fabric UUID: 5ca1ab1e-a007-feed-f00d-cab3fe13249e Time-To-Live: 1 server_uuid address status mode weight ------------------------------------ ------------------- --------- ---------- ------ 19e625e0-ea04-11e5-b192-0800273bba44 192.168.1.208:13306 SECONDARY READ_ONLY 1.0 5592ca61-ae26-11e5-8586-08002732e007 192.168.1.209:13306 PRIMARY READ_WRITE 1.0 7cb26cac-ea9d-11e5-a9a1-080027d9fe9c 192.168.1.207:13306 SECONDARY READ_ONLY 1.0
16、激活HA组
mysqlfabric group activate mydb_group
17、测试HA
[root@node10 ~]# service mysqld stop Stopping mysqld: [ OK ]
[root@node06 ~]# mysqlfabric group lookup_servers mydb_group Fabric UUID: 5ca1ab1e-a007-feed-f00d-cab3fe13249e Time-To-Live: 1 server_uuid address status mode weight ------------------------------------ ------------------- --------- ---------- ------ 19e625e0-ea04-11e5-b192-0800273bba44 192.168.1.208:13306 SECONDARY READ_ONLY 1.0 5592ca61-ae26-11e5-8586-08002732e007 192.168.1.209:13306 FAULTY READ_WRITE 1.0 7cb26cac-ea9d-11e5-a9a1-080027d9fe9c 192.168.1.207:13306 PRIMARY READ_WRITE 1.0
