4、System-V方式启动amoeba，脚本如下：

#!/bin/sh

# chkconfig:   62
# Author: fansik

# description: amoeba 2.2.0 AutoRun Servimces

# /etc/init.d/amoeba

#

# Run-level Startup script for the Oracle Instance, Listener, and

# Web Interface

export JAVA_HOME=/usr/local/jdk1.

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

NAME=Amoeba

AMOEBA_BIN=/usr/local/amoeba/bin

PIDFILE=/usr/local/amoeba/Amoeba-MySQL.pid

SCRIPTNAME=/etc/init.d/amoeba

case "$1" in

    start)

        echo -n "Starting $NAME... "

        $AMOEBA_BIN/amoeba start &>/dev/null &

        echo -e "\t[ \033[1;32mok\033[0m ]"

        ;;

    stop)

        echo -n "Stoping $NAME... "

        $AMOEBA_BIN/amoeba stop &>/dev/null

        echo -e "\t[ \033[1;32mok\033[0m ]"

        ;;

    restart)

        echo -n "Restarting $NAME..."

        $AMOEBA_BIN/amoeba stop &>/dev/null

        sleep

        $AMOEBA_BIN/amoeba start &>/dev/null &

        echo -e "\t[ \033[1;32mok\033[0m ]"

        ;;

    *)

        echo "Usage: $SCRIPTNAME {start|stop|restart}"

        exit

        ;;

esac

5、开机自启动设置
chmod +x /etc/init.d/amoeba
chkconfig --add amoeba
chkconfig amoeba on
6、搭建过程中遇到的问题
    在测试读写分离的时候不能开启从库复制，也就是要登录slave数据库执行stop slave，否则无法验证而且在主库停掉服务后，也是无法读的，
因为主库停掉以后，从库的状态会变成Slave_IO_Running: No。

　　在启动amoeba的时候需要将Xss：每个线程的堆栈大小增加，否则无法启动服务，默认大小是128，调整为256即可，配置位置就是amoeba的bin目录下，一个叫做amoeba的文件。
