centos6.x安装mycat

1 下载 mycat 1.6版本

  wget http://dl.mycat.io/1.6-RELEASE/Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz

2 移动到/usr/local 下 解压

  tar -zxvf  Mycat-server-1.6-RELEASE-20161028204710-linux.tar.gz

3 配置环境变量

   vim /etc/profile

  末尾追加

   export MYCAT_HOME=/usr/local/mycat

 重载 配置文件

   source /etc/profile

检测环境配置正确否

 [root@localhost ~]# echo $MYCAT_HOME
/usr/local/mycat

4修改wrapper.conf文件

cd /usr/local/mycat/conf vim wrapper.conf

# Java Application

wrapper.java.command=/usr/java/jdk1.8.0_65/bin/java

5配置schema

6 启动mycat

启动: mycat start mycat 就已经启动了 端口8066 关闭mycat: mycat stopmycat status       查看状态mycat console   查看启动过程[root@bogon home]# mycat consoleRunning Mycat-server...wrapper  | --> Wrapper Started as Consolewrapper  | Launching a JVM...jvm 1    | Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=64M; support was removed in 8.0jvm 1    | Wrapper (Version 3.2.3) http://wrapper.tanukisoftware.orgjvm 1    |   Copyright 1999-2006 Tanuki Software, Inc.  All Rights Reserved.jvm 1    | jvm 1    | log4j 2015-12-01 18:05:45 [./conf/log4j.xml] load completed.jvm 1    | MyCAT Server startup successfully. see logs in logs/mycat.log

这些信息表示可正常启动

问题：如果启动不起来，或者启动后ps aux | grep mycat查不到，则可能是hosts需要修改 将本机的名称加入hosts[root@bogon home]# vi /etc/hosts            加入机器名bogon127.0.0.1   localhost bogon localhost.localdomain localhost4 localhost4.localdomain4::1         localhost bogon localhost.localdomain localhost6 localhost6.localdomain6
