3 ameoba安装配置
?
3.1 安装配置JDK
[[email protected] ~]# rpm -ivh jdk-7u67-linux-x64.rpm
[[email protected] ~]# cd /usr/java/
?
修改环境变量
?
[[email protected] ~]# vim /etc/profile.d/java.sh
[[email protected] ~]# cat /etc/profile.d/java.sh
export JAVA_HOME=/usr/java/latest
export PATH=$JAVA_HOME/bin:$PATH
#即时生效配置文件
[[email protected] ~]# . /etc/profile.d/java.sh
测试：执行java -version，正确的话应该会显示：
[[email protected] ~]# java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

lftp 172.16.0.1:/pub/Sources/6.x86_64/amoeba>
[[email protected] ~]# mkdir /usr/local/amoeba
[[email protected] ~]# tar xf amoeba-mysql-binary-2.2.0.tar.gz -C /usr/local/amoeba
?

?
[[email protected] amoeba]# bin/amoeba start
?

#解决方法
[[email protected] bin]# pwd
/usr/local/amoeba/bin

3.4 使用验证
?
# 登录验证
[[email protected] ~]# mysql -h127.0.0.1 -uroot -p -P3306
mysql> show master status;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000003 | 961 | | |
+------------------+----------+--------------+------------------+
1 row in set (0.06 sec)

测试读写分离：
在安装的amoea的节点node15上，创建一个数据库，分别查看后端节点master(node16),slave(node17)的所有数据库：
mysql> create database amoeba_test;
Query OK, 1 row affected (0.11 sec)
?
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| amoeba_test |
| mysql |
| performance_schema |
| test |
+--------------------+
5 rows in set (0.00 sec)
?
[[email protected] ~]# mysql
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| mysql |
| performance_schema |
| test |
+--------------------+
4 rows in set (0.07 sec)

# 从amoeba接口登录创建数据库amoeba_test后，再从主库的接口中去查询数据库已创建，说明写入确实是落在了主库节点上；
# 若要验证ameoba对于读操作的调度，则需要暂时停止从库的复制操作，然后在主库上更新数据，这样从ameoba读取数据将出现
