mysql主从配置以及基于amoeba实现读写分离

mysql主从配置以及基于amoeba实现读写分离

首先硬件设备 ：ubuntu12.04 server 64

三台主机ip地址：master 192.168.1.8 slave 192.168.1.15

amoeda 192.168.1.16

软件版本： mysql 5.5 java6 amoeba 3.0.5

首先配置mysql主从关系

a，安装配置master节点

root@i-70bl6kfl:~# apt-get install mysql-server

b， 配置master

root@i-zvjoik10:~# vi /etc/mysql/my.cnf

bind-address = 0.0.0.0

[mysqld]

server-id=1

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

c，同理安装slave节点并配置

# vi /etc/mysql/my.cnf

bind-address = 0.0.0.0

[mysqld]

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

server_id = 2

relay_log =mysql-relay-bin

log_slave_updates = 1

d，在主从节点上都赋予mysql远程访问权限

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.00 sec)

查看master信息

mysql> show master status;

+------------------+----------+--------------+------------------+

| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |

+------------------+----------+--------------+------------------+

| mysql-bin.000001 | 342 | | |

+------------------+----------+--------------+------------------+

1 row in set (0.00 sec)

slave中启动 Master - Slave 复制功能。

分别执行以下命令

Sql代码 收藏代码

mysql> slave stop

-> ;

Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> change master to

-> master_host='192.168.1.8',

-> master_user='root',

-> master_password='123456',

-> master_log_file='mysql-bin.000001',

-> master_log_pos=342;

Query OK, 0 rows affected (0.02 sec)

mysql> start slave;

Query OK, 0 rows affected (0.00 sec)

e，执行完后，测试下主从是否配置成功 在主节点上创建个数据库

mysql> create database anchora;

然后安装proxy amoeba；

a,在amoeba上安装java环境

apt-get install openjdk-6-jre-headless

export JAVA_HOME=/usr/lib/jvm/java-6-openjdk-amd64

root@i-70bl6kfl:~# source /etc/profile

b，安装amoeba

把下载的压缩包解压完了之后放到 /usr/local/ 目录下即可。

# mkdir /usr/local/amoeba

root@i-70bl6kfl:/usr/local/amoeba# unzip amoeba-mysql-3.0.5-RC-distribution.zip

root@i-70bl6kfl:/usr/local/amoeba# /bin/cp amoeba-mysql-3.0.5-RC/* /usr/local/amoeba/

bin/cp: omitting directory `amoeba-mysql-3.0.5-RC/benchmark'

/bin/cp: omitting directory `amoeba-mysql-3.0.5-RC/bin'

/bin/cp: omitting directory `amoeba-mysql-3.0.5-RC/conf'

/bin/cp: omitting directory `amoeba-mysql-3.0.5-RC/lib'

root@i-70bl6kfl:/usr/local/amoeba# /bin/cp -rf amoeba-mysql-3.0.5-RC/* /usr/local/amoeba

我们用到dbServer.xml 和 amoeba.xml

a，修改可以访问的ip（这里所有的ip都可以访问）

root@i-70bl6kfl:/usr/local/amoeba/conf# vi access_list.conf

#218.85.*.*:no

127.0.0.1:yes

b，配置dbSerers.xml实现其代理 入口数据库为anchora我刚才创建的

root@i-70bl6kfl:/usr/local/amoeba/conf# vi dbServers.xml

修改20-28行

<!-- mysql port -->

<property name="port">3306</property>

<!-- mysql schema -->

<property name="schema">anchora</property>

<!-- mysql user -->

<property name="user">root</property>

<property name="password">123456</property>

46-53行的mysql主从服务器的数据库的ip

<dbServer name="server1" parent="abstractServer">

<factoryConfig>

<!-- mysql ip -->

<property name="ipAddress">192.168.1.8</property>

</factoryConfig>

</dbServer>

<dbServer name="server2" parent="abstractServer">

<factoryConfig>

<!-- mysql ip -->

<property name="ipAddress">192.168.1.15</property>

</factoryConfig>

</dbServer>

c，配置 amoeba.xml 在这里可以修端口代理密码和读写分离。

root@i-70bl6kfl:/usr/local/amoeba/conf# vi amoeba.xml

30行

<property name="password">123456</property>

86行

<property name="writePool">server1</property>

<property name="readPool">server2</property>

保存推出，启动amoeba

root@i-70bl6kfl:/usr/local/amoeba/bin# ./launcher

然后远程测试连接

root@i-70bl6kfl:~# mysql -u root -p -h 192.168.1.16 --port 8066

Enter password:

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
