4、System-V方式启动amoeba,脚本如下:
#!/bin/sh
# chkconfig: 12345 62 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/jdk1.8
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 " [ 33[1;32mok 33[0m ]"
;;
stop)
echo -n "Stoping $NAME... "
$AMOEBA_BIN/amoeba stop &>/dev/null
echo -e " [ 33[1;32mok 33[0m ]"
;;
restart)
echo -n "Restarting $NAME..."
$AMOEBA_BIN/amoeba stop &>/dev/null
sleep 1
$AMOEBA_BIN/amoeba start &>/dev/null &
echo -e " [ 33[1;32mok 33[0m ]"
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart}"
exit 1
;;
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。
