架构描写叙述：
一台主机上安装4个MySQL 服务，当中一个MySQL服务用于存储MySQL Fabric后台数据；另外3个MySQL服务用于主从架构測试。一个主+两个从。
第一部分：二进制方式安装MySQL 5.6.19
1. 操作系统
CentOS release 6.2 (Final)
2. 创建用户和组
[root@mymaster1 ~]# groupadd mysql
[root@mymaster1 ~]# useradd -r -g mysqlmysql
3. 解压安装包（解压到你想存储数据库数据的地方）
[root@mymaster1 ~]# cd /data
[root@mymaster1 data]# tar -xzvf/root/mysql_soft/mysql-5.6.19-linux-glibc2.5-x86_64.tar.gz
[root@mymaster1 data]# ln -smysql-5.6.19-linux-glibc2.5-x86_64 mysql
4. 查看解压情况
[root@mymaster1 data]# ll
总用量 20
lrwxrwxrwx. 1 root root 34 6月 27 15:31 mysql -> mysql-5.6.19-linux-glibc2.5-x86_64
drwxr-xr-x. 13 rootroot 4096 6月 27 15:31 mysql-5.6.19-linux-glibc2.5-x86_64
5. 改动目录所属用户和组为mysql：
[root@mymaster1 data]# cd mysql
[root@mymaster1 mysql]# chown -R mysql:mysql.
6. 安装数据库
[root@mymaster1 mysql]#scripts/mysql_install_db --user=mysql --basedir=/data/mysql--datadir=/data/mysql/data
WARNING: The host'mymaster1.localdomain' could not be looked up with /data/mysql/bin/resolveip.
This probably means thatyour libc libraries are not 100 % compatible
with this binary MySQLversion. The MySQL daemon, mysqld, should work
normally with theexception that host name resolving will not work.
This means that youshould use IP addresses instead of hostnames
when specifying MySQLprivileges !
当出现上面警告时，解决方法是：在/etc/hosts配置文件里添加IP地址和主机名的映射
如
[root@mymaster1 Packages]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
IP地址 mymaster1.localdomain
正确的提示信息例如以下：
[root@mymaster1 mysql]#scripts/mysql_install_db --user=mysql --basedir=/data/mysql--datadir=/data/mysql/data

To start mysqld at boot time you have tocopy
support-files/mysql.server to the rightplace for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THEMySQL root USER !
To do so, start the server, then issue thefollowing commands:
/data/mysql/bin/mysqladmin -u root password 'new-password'
/data/mysql/bin/mysqladmin -u root -h mymaster1.localdomain password'new-password'
Alternatively you can run:
/data/mysql/bin/mysql_secure_installation
which will also give you the option ofremoving the test
databases and anonymous user created bydefault. This is
strongly recommended for productionservers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd. ; /data/mysql/bin/mysqld_safe &
You can test the MySQL daemon withmysql-test-run.pl
cdmysql-test ; perl mysql-test-run.pl
Please report any problems athttp://bugs.mysql.com/
The latest information about MySQL isavailable on the web at
http://www.mysql.com
Support MySQL by buying support/licenses athttp://shop.mysql.com
New default config file was created as/data/mysql/my.cnf and
will be used by default by the server whenyou start it.
You may edit this file to change serversettings
7. 改动相关文件夹权限，提高安全性：
[root@mymaster1 mysql]# chown -R root .
[root@mymaster1 mysql]# chown -R mysql data
8. 配置MySQL服务为主机服务，即能用service mysql start启动服务
[root@mymaster1 mysql]# cpsupport-files/mysql.server /etc/init.d/mysql
[root@mymaster1 mysql]# vi +46 /etc/init.d/mysql
把以下的
basedir=
datadir=
改动为
basedir=/data/mysql
datadir=/data/mysql/data
【备注】另外三个mysql服务。能够在这里复制为例如以下形式：
[root@mymaster1 mysql]#cp support-files/mysql.server /etc/init.d/mysql.3001
[root@mymaster1 mysql]#vi +46 /etc/init.d/mysql.3001
9. 改动配置文件
[root@mysqlfabric mysql_3001]# cd/opt/mysql
[root@mysqlfabric mysql]# vi my.cnf
改动对应的port号：
[mysqld]
character-set-server=gbk
lower_case_table_names=1
default_storage_engine=myisam
port=3306
gtid_mode=ON
log-bin
log-slave-updates
enforce-gtid-consistency
server_id=1 #【不同的MySQL服务，改动为不同的id】
【备注】：上面的蓝色字体是用于开启GTID复制參数
10. 启动数据库
[root@mymaster1 mysql]# service mysql start
Starting MySQL[确定]
11. 改动数据库rootpassword
[root@mymaster1 mysql]#/data/mysql/bin/mysqladmin -u root password 'root'
[root@mymaster1 mysql]#/data/mysql/bin/mysqladmin -u root -h mymaster1.localdomain password ' root'
12. 改动环境变量，把mysql运行文件路径加入到环境变量中
[root@mymaster1 mysql]# vi /etc/profile
PATH=$PATH:/data/mysql/bin
export PATH
13. 測试登录
[root@mymaster1 mysql]# mysql -u root -p
Enter password:

14. 加入用于复制的用户（3001上）
mysql> CREATE USER 'repl'@'%' IDENTIFIEDBY 'repl';
Query OK, 0 rows affected (0.03 sec)
mysql> GRANT REPLICATION SLAVE ON *.* TO'repl'@'%';
Query OK, 0 rows affected (0.00 sec)
15. 开启复制（3002，3003上）
使用change master to 命令开启复制
mysql> start slave;
mysql> show slave status\G
以下是重要步骤，安装Fabric
第二部分：安装MySQL Fabric
1. 安装Connector/Python
[root@mysqlfabric soft]# rpm -ivhmysql-connector-python-1.2.2-1.el6.noarch.rpm
注：MySQL Fabric使用Connector/Python来连接MySQL，所以必须安装这个连接器
2. 安装Fabric
因为Fabric包括在mysql-utilities，所以仅仅须要安装mysql-utilities就能够了。
[root@mysqlfabric soft]# rpm -ivh mysql-utilities-1.4.3-1.el6.noarch.rpm
Preparing... ########################################### [100%]
1:mysql-utilities ########################################### [100%]
3. 配置MySQL Fabric
配置MySQL Fabric须要创建MySQL用户，创建启动配置文件和安装Fabric数据存储
l 创建用户
登录port号为3306的mysql 服务【作为Fabric后台数据存储】
[root@mysqlfabric soft]# mysql -u root -P3306 -p –h mysqlfabric.localdomain
【注】上面登录时须要加主机名。由于一台server安装了多个mysql服务
mysql> CREATE USER 'fabric'@'mysqlfabric.localdomain'IDENTIFIED BY 'fabric';
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT ALL ON fabric.* TO'fabric'@'mysqlfabric.localdomain';
Query OK, 0 rows affected (0.00 sec)
l 在另外三台MySQL 服务下创建以下的用户。用于连接被管理的MySQL服务
[root@mysqlfabric mysql_3003]# mysql -uroot-P3001 -p -h mysqlfabric.localdomain
mysql> GRANT ALL ON *.* TO 'fabric'@' mysqlfabric.localdomain';
Query OK, 0 rows affected (0.00 sec)
mysql> SET PASSWORD FOR 'fabric'@' mysqlfabric.localdomain' = PASSWORD('fabric');
Query OK, 0 rows affected (0.00 sec)
[root@mysqlfabric mysql_3003]# mysql -uroot-P3002 -p -h mysqlfabric.localdomain
mysql> GRANT ALL ON *.* TO 'fabric'@' mysqlfabric.localdomain';
Query OK, 0 rows affected (0.00 sec)
mysql> SET PASSWORD FOR 'fabric'@' mysqlfabric.localdomain' = PASSWORD('fabric');
Query OK, 0 rows affected (0.00 sec)
[root@mysqlfabric mysql_3003]# mysql -uroot-P3003 -p -h mysqlfabric.localdomain
mysql> GRANT ALL ON *.* TO 'fabric'@' mysqlfabric.localdomain';
Query OK, 0 rows affected (0.00 sec)
mysql> SET PASSWORD FOR 'fabric'@' mysqlfabric.localdomain' = PASSWORD('fabric');
Query OK, 0 rows affected (0.00 sec)
l 配置文件
打开配置文件/etc/mysql/fabric.cfg
[root@mysqlfabric soft]# vi/etc/mysql/fabric.cfg
改动[storage]部分信息：
[storage]
auth_plugin = mysql_native_password
database = fabric
user = fabric
address = mysqlfabric.localdomain:3306
connection_delay = 1
connection_timeout = 6
password =fabric
connection_attempts = 6
[sharding]
mysqldump_program =/opt/mysql/bin/mysqldump
mysqlclient_program =/opt/mysql/bin/mysql
4. 填充MySQL Fabric后台存储数据（创建库和表）
[root@mysqlfabric mysql]# mysqlfabric manage setup--param=storage.user=fabric --param=storage.password=fabric
[INFO] 1404205520.480905 - MainThread -Initializing persister: user (fabric), server (mysqlfabric.localdomain:3306),database (fabric).
Finishing initial setup
=======================
Password for admin user is not yet set.
Password for admin/xmlrpc:
Repeat Password: admin
Password set.admin
5. 启动MySQL Fabric节点
[root@mysqlfabric ~]# mysqlfabric managestart
假设想在后台执行。能够加上—daemonize选项
停止方式：
[root@mysqlfabric ~]# mysqlfabric managestop
6. 配置MySQL Fabric用于主从复制
l 创建组
[root@mysqlfabric ~]# mysqlfabric groupcreate my_group
Password for admin:
Procedure :
{ uuid = d7d4581c-a819-47c2-ad31-37c5390e93bd,
finished = True,
success = True,
return = True,
activities =
}
l 把MySQL服务加入到组
错误信息：
[root@mysqlfabric ~]# mysqlfabric group addmy_group mysqlfabric.localdomain:3001
Procedure :
{ uuid = 5c373b82-d369-413d-a2e0-5b4c60d506c0,
finished = True,
success = False,
return = ServerError: Server (be642e20-00d3-11e4-8d96-0050568f7be4)does not have the binary log or gtid enabled.,
activities =
}
正确信息：
[root@mysqlfabric mysql_3003]# mysqlfabricgroup add my_group mysqlfabric.localdomain:3001
Procedure :
{ uuid = baafd4d2-dba8-4863-9a76-74a3e6153065,
finished = True,
success = True,
return = True,
activities =
}
[root@mysqlfabric mysql_3003]# mysqlfabric group add my_groupmysqlfabric.localdomain:3002
Procedure :
{ uuid = 2f336426-b12d-4bd2-ab71-0b6c9d513466,
finished = True,
success = True,
return = True,
activities =
}
[root@mysqlfabric mysql_3003]# mysqlfabric group add my_groupmysqlfabric.localdomain:3003
Procedure :
{ uuid = 844eba0a-a7bc-4e67-8359-3ab53d0520c7,
finished = True,
success = True,
return = True,
activities =
}
l 把组内一个MySQL服务提升为一个master:
加入MySQL服务到组后，Fabric不会意识到不论什么主从复制的架构。必须提升组内不论什么一个MySQL服务为主master,其他服务设置为slave。提升命令例如以下：
[root@mysqlfabric ~]# mysqlfabric grouppromote my_group
当组内有一个主master时，新加入到组内的新MySQL服务将自己主动成为slave。
也能够使用相同的命令使组内的master降级为slave。另选一个slave为master
l 查看my_group组Mysql服务的信息：
[root@mysqlfabric ~]# mysqlfabric grouplookup_servers my_group
Command :
{ success = True
return = [{'status':'SECONDARY', 'server_uuid': 'be642e20-00d3-11e4-8d96-0050568f7be4', 'mode':'READ_ONLY', 'weight': 1.0, 'address': 'mysqlfabric.localdomain:3001'},{'status': 'SECONDARY', 'server_uuid': 'c696a608-00d5-11e4-8da3-0050568f7be4','mode':
'READ_ONLY', 'weight': 1.0, 'address': 'mysqlfabric.localdomain:3002'},{'status': 'PRIMARY', 'server_uuid': '1230c8cb-00d7-11e4-8dac-0050568f7be4','mode': 'READ_WRITE', 'weight': 1.0, 'address':'mysqlfabric.localdomain:3003'}]
activities =
}
l 查看my_group组MySQL服务健康状态信息：
[root@mysqlfabric ~]# mysqlfabric grouphealth my_group
Command :
{ success = True
return ={'1230c8cb-00d7-11e4-8dac-0050568f7be4': {'status': 'PRIMARY', 'is_alive':True, 'threads': {}}, 'be642e20-00d3-11e4-8d96-0050568f7be4': {'status':'SECONDARY', 'is_alive': True, 'threads': {}},'c696a608-00d5-11e4-8da3-0050568f7be4': {'status':
'SECONDARY', 'is_alive':True, 'threads': {}}}
activities =
}
l 自己主动检測组内MySQL服务故障：
假设想在primary失败时。secondary能自己主动提升为primary，运行以下步骤：
[root@mysqlfabric ~]# mysqlfabric group activate my_group
Procedure :
{ uuid = 4ee1bd23-0fab-46f0-a336-9e4731117370,
finished = True,
success = True,
return = True,
activities =
}
【备注】假设不想让fabric自己主动检測故障，能够取消自己主动监控功能：
[root@mysqlfabric ~]# mysqlfabric group deactivate my_group
7. 故障測试
[root@mysqlfabric ~]# service mysql.3003 stop
[root@mysqlfabric ~]# mysqlfabric group lookup_servers my_group
Command :
{ success = True
return = [{'status':'SECONDARY', 'server_uuid': 'be642e20-00d3-11e4-8d96-0050568f7be4', 'mode':'READ_ONLY', 'weight': 1.0, 'address': 'mysqlfabric.localdomain:3001'},
{'status': 'PRIMARY', 'server_uuid':'c696a608-00d5-11e4-8da3-0050568f7be4', 'mode': 'READ_WRITE', 'weight': 1.0,'address': 'mysqlfabric.localdomain:3002'}, {'status': 'FAULTY','server_uuid': '1230c8cb-00d7-11e4-8dac-0050568f7be4',
'mode': 'READ_WRITE','weight': 1.0, 'address': 'mysqlfabric.localdomain:3003'}]
activities =
}
说明已经把3002提升为primary
8. Mysqlfabric相关命令：
l 把一个MySQL服务移出组：
mysqlfabric group remove my_groupserver_uuid
如：
[root@mysqlfabric ~]#mysqlfabric groupremove my_group 1230c8cb-00d7-11e4-8dac-0050568f7be4
master不能被移出组，必须disablemaster后才干够移出：
mysqlfabric group demote my_group
l 删除组(组内已经没有MySQL服务)
mysqlfabric group destroy my_group
l 强制删除组（组内有MySQL服务）
mysqlfabric group destroy my_group --force
奋斗的路很幸苦。部署到此介绍，再接再厉。
