准备五台主机
192.168.200.10主
192.168.200.11 从
192.168.200.12 从
192.168.200.14
192.168.200.15 客户端
在所有主机都关闭防火墙
systemctl stop firewalld
iptabales -F
setenforce 0
安装mariadb mariadb-server
yum -y install mariadb
yum -y install mariadb-server
在第四台主机上Amoeba上安装java环境
chmod +x jdk-6u31-linux-x64.bin
./jdk-6u31-linux-x64.bin
[root@localhost ~]# mv jdk1.6.0_14/ /usr/local/jdk1.6
[root@localhost ~]# vim /etc/profile

在主两个从的主机上
配置 Amoeda读写分离，两个Slave读负载均衡
[root@localhost ~]# mysql
MariaDB [(none)]> grant all on *.* to ‘test‘@‘192.168.200.%‘ identified by‘123.com‘;
Query OK, 0 rows affected (0.10 sec)
MariaDB [(none)]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
在mysql主服务器上创建一个表，会自动同步到各个从服务器上，然后关掉各个从服务器上的Slave功能，在分别插入语句测试。
主服务器
MariaDB [(none)]> create database db_test;
Query OK, 1 row affected (0.01 sec)
MariaDB [(none)]> use db_test;
Database changed
MariaDB [db_test]> create table student (id int(10),name varchar(10),address varchar(20));
Query OK, 0 rows affected (0.39 sec)
分别在两台从服务器上
MariaDB [db_test]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| db_test |
| mysql |
| performance_schema |
| test |
+--------------------+
5 rows in set (0.00 sec)
MariaDB [(none)]> stop slave;
Query OK, 0 rows affected (0.03 sec)
在主服务器上
MariaDB [db_test]> insert into student values(‘1‘,‘crushlinux‘,‘this_is_master‘);
Query OK, 1 row affected (0.02 sec)
在从服务器上1
MariaDB [(none)]> use db_test
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [db_test]> insert into student values(‘2‘,‘crushlinux‘,‘this_is_slave1‘);
Query OK, 1 row affected (0.10 sec)
在从服务器上2
MariaDB [(none)]> use db_test
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [db_test]> insert into student vlues(‘3‘,‘crushlinux‘,‘this_is_slave3‘);
Query OK, 1 row affected (0.10 sec)
测试读操作：
在测试机上第一次查询结果
MySQL [db_test]> select * from student;
+------+------------+----------------+
| id | name | address |
+------+------------+----------------+
| 2 | crushlinux | this_is_slave2 |
+------+------------+----------------+
1 row in set (0.00 sec)
MySQL [db_test]> select * from student;
+------+------------+----------------+
| id | name | address |
+------+------------+----------------+
| 3 | crushlinux | this_is_slave3 |
+------+------------+----------------+
1 row in set (0.15 sec)
在两个从服务器上
MariaDB [(none)]> start slave;
Query OK, 0 rows affected (0.00 sec)
测试写操作：
在客户端上插入一条语句
MySQL [(none)]> use db_test
MySQL [db_test]> insert into student values(‘4‘,‘crushlinux‘,‘write_test‘);
Query OK, 1 row affected (0.00 sec)
MySQL [db_test]> select * from student;
+------+------------+----------------+
| id | name | address |
+------+------------+----------------+
| 2 | crushlinux | this_is_slave2 |
+------+------------+----------------+
1 row in set (0.01 sec)
MySQL [db_test]> select * from student;
+------+------------+----------------+
| id | name | address |
+------+------------+----------------+
| 3 | crushlinux | this_is_slave3 |
| 1 | crushlinux | this_is_master |
| 4 | crushlinux | write_test |
+------+------------+----------------+
3 rows in set (0.01 sec)
MySQL [db_test]> select * from student;
+------+------------+----------------+
| id | name | address |
+------+------------+----------------+
| 2 | crushlinux | this_is_slave2 |
| 1 | crushlinux | this_is_master |
| 4 | crushlinux | write_test |
