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/mysql3309
2、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。
[client]
no-beep
socket=/software/mysql/mysql3307/mysql.sock
# pipe
# socket=0.0
port=3307
[mysqld]
basedir=/software/mysql/mysql3307

#
创建用户组
#创建用户组
groupadd -r mysql
useradd -r -g mysql mysql
#设置用户组
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）。

把/usr/local/mysql修改成相应的mysql目录。
#mysq.server的部分代码
mysqld_pid_file_path=

then

else
bindir="$basedir/bin"
if test -z "$datadir"
then
datadir="$basedir/data"
fi
sbindir="$basedir/sbin"
libexecdir="$basedir/libexec"
fi
3、mysql配置主从
在master服务器上（3307端口）输入
show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000006 | 154 | | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.13 sec)
在slave服务器上（3308和3309端口）输入
stop slave;
change master to master_host='localhost', master_user='root', master_password='root',master_log_file='mysql-bin.000006',master_log_pos=154,master_port=3307;
start slave;
测试：
在从服务器上输入show slave status;
mysql> show slave status;

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:

mysql> exit;
Bye
[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/amoeba
6、amoeba配置
amoeba配置主要是amoeba.xml和dbServers.xml两个文件。

进入三个mysql实例。
输入命令，其中的root应该设置为dbServers.xml中设置的用户名和密码。
grant all on *.* to'root'@'%' identified by 'root';
flush privileges;
7、amoeba运行
在控制台输入
[root@iz2zeaf5jdjve80rjlsjgnz support-files]# /software/amoeba/bin/amoeba
amoeba start|stop
出现amoeba start|stop说明安装成功。
输入/software/amoeba/bin/amoeba start运行
[root@iz2zeaf5jdjve80rjlsjgnz support-files]# /software/amoeba/bin/amoeba start
log4j:WARN log4j config load completed from file:/software/amoeba/conf/log4j.xml

关闭两个slave服务器
kill -9 2772 9260 10010 12338
在8066端口测试
mysql> insert into admin values('r','r');
Query OK, 1 row affected (0.81 sec)
mysql> select * from admin;
2013 - Lost connection to MySQL server during query
此时，读取失败，写入正常。
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。
常见问题

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
