从零开始：Mysql基于Amoeba的集群搭建
准备环境
1、mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
2、amoeba-mysql-binary-2.0.1-BETA.tar.gz
3、Centos7
下载安装配置运行
1、mysql安装
使用wget命令下载安装
//创建目录
mkdir /software/mysql
cd /software/mysql
wget https://dev.mysql.com/get/downloads/mysql-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz下载安装完成后使用tar命令解压
tar zxvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz /software/mysql/mysql3307我这里搭建的是一主两从模式，所以需要三个mysql实例。
cp -rf /software/mysql/mysql3307 /software/mysql/mysql3308
cp -rf /software/mysql/mysql3307 /software/mysql/mysql33092、mysql配置
在每个实例下的根路径创建一个my.cnf文件，一个data目录。
对每个实例修改相应的端口和目录。

chown -R mysql:mysql /software/mysql/
chown -R mysql /software/mysql/使用mysqld命令初始化mysql。
cd /software/mysql/mysql3307/bin
./mysqld --user=mysql --basedir=/software/mysql/mysql3307 --datadir=/software/mysql/mysql3307/data --initialize
./mysqld --user=mysql --defaults-file=/software/mysql/mysql3307/my.cnf
cd /software/mysql/mysql3308/bin
./mysqld --user=mysql --basedir=/software/mysql/mysql3308 --datadir=/software/mysql/mysql3308/data --initialize
./mysqld --user=mysql --defaults-file=/software/mysql/mysql3308/my.cnf
cd /software/mysql/mysql3309/bin
./mysqld --user=mysql --basedir=/software/mysql/mysql3309 --datadir=/software/mysql/mysql3309/data --initialize
./mysqld --user=mysql --defaults-file=/software/mysql/mysql3309/my.cnf初始化完成时会输出一个mysql的初始密码（Tsiq_elgs7iQ）。

1 row in set (0.88 sec)其中
Slave_IO_State Waiting for master to send event
Slave_IO_Running Yes
Slave_SQL_Running Yes表示主从运行成功。
4、mysql运行
使用mysql.server运行mysql实例
[root@iz2zeaf5jdjve80rjlsjgnz bin]# cd /software/mysql/mysql3307/support-files
[root@iz2zeaf5jdjve80rjlsjgnz support-files]# ./mysql.server start
Starting MySQL.Logging to '/software/mysql/mysql3307/data/iz2zeaf5jdjve80rjlsjgnz.err'.
... [ OK ]
进入mysql控制台
[root@iz2zeaf5jdjve80rjlsjgnz support-files]# cd /software/mysql/mysql-5.7.24-linux-glibc2.12-x86_64/bin
[root@iz2zeaf5jdjve80rjlsjgnz bin]# ./mysql -u root -p
Enter password:

[root@iz2zeaf5jdjve80rjlsjgnz bin]# 使用navicat测试连接
5、amoeba安装
使用wget下载amoeba
//创建目录
mkdir /software/amoeba
cd /software/amoeba
wget https://jaist.dl.sourceforge.net/project/amoeba/Amoeba%20for%20mysql/2.x/amoeba-mysql-binary-2.0.1-BETA.tar.gz使用tar命令解压
tar xf amoeba-mysql-binary-2.0.1-BETA.tar.gz -C /software/amoeba6、amoeba配置
amoeba配置主要是amoeba.xml和dbServers.xml两个文件。

踩坑
建立三个mysql服务器，一定要配置
log-bin=mysql-bin //日志文件
server-id = 2 //服务器id，不要和其他的相同
replicate-do-db=test //同步的数据库，可以不指定，默认是所有数据库
log-slave-updates
sync_binlog=1
slave-net-timeout=60在使用show slave status;命令时，要有提示下面的，才会开启主从同步。
Slave_IO_State Waiting for master to send event
Slave_IO_Running Yes
Slave_SQL_Running Yes同时，要关注Replicate_Do_DB的配置，比如配置的是test，那么就要在master创建一个test数据库，之后的同步操作才会在test里面进行，不会在其他数据库里面执行。

amoeba找不到JAVA_HOME
在amoeba文件中第一行添加
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64/jre后面跟着的是jdk的路径。
amoeba运行时提示The stack size specified is too small, Specify at least 160k.
在amoeba文件中修改
