amoeba的运行环境依靠java的jdk;
下面执行amoeba的安装不走
# mkdir /usr/local/src/amoeba
上传文件:amoeba-mysql-binary-2.2.0.tar.gz
# tar –xvf amoeba-mysql-binary-2.2.0.tar.gz
bin 执行文件目录
conf 配置文件目录
1.1.1 配置amoeba
配置主、从mysql服务器链接信息等,下面配置文件中红色字体为需要注意或修改的地方;

1.1.2 打开8066端口
# /sbin/iptables -I INPUT -p tcp --dport 8066 -j ACCEPT
# /etc/rc.d/init.d/iptables save #修改生效
# /etc/init.d/iptables status #查看配置
1.1.3 启动amoeba
# ./bin/amoeba start 或 # ./bin/amoeba start &
1.1.4 停止amoeba
# ./bin/amoeba stop
1.1.5 问题
1、JAVA_HOME不认
jdk安装后测试无问题java –version,但启动amoeba就是报错JAVA_HOME找不到。就修改/amoeba/bin/amoeba文件,在文件最开头直接写入JAVA_HOME环境变量。
JAVA_HOME=/usr/local/src/java/jdk1.7.0_51
2、java栈设置小
默认配置Xss比较小128k,启动时提示太小,则修改/amoeba/bin/amoeba文件,修改为256k即可。
DEFAULT_OPTS="-server -Xms256m -Xmx256m -Xss256k"
3、amoeba连接的mysql都要开放访问权限
否则访问拒绝,无法执行SQL语句
