  • mycat installation and testing:

     安装之前,我已经搭建了192.168.0.135和192.168.0.153这两台服务器,且都安装了mysql,这个mycat我是在192.168.0.135服务器上安装的
     1、下载安装包:
                 链接:https://pan.baidu.com/s/13jk5WWTFm8SioBxk88GBtA 
                 提取码:072h
     2、解压到/usr/local目录下面
                通过xftp将安装包移动到/opt目录下面
                在/opt目录下面解压到/usr/local下:unzip mycat-linux.zip -d /usr/local
     3、配置服务器和分片表
              为什么要配置分片和服务器?

              修改schema.xml,修改如下,各个参数含义都已经写明:

    4、启动,并且测试是否成功
                /usr/local/mycat/bin/mycat  console start &------->这个表示后台运行,并且打印出日志(这样可以看启动不成功是因为什么)

                启动成功后,通过mysql -uroot -proot -P3310 -h192.168.0.135测试,看能不能进去mysql服务,成功如下:

5、开放3310端口,并且用navicat测试是否能够连接
           vi /etc/sysconfig/iptables
           复制22端口的开放方式,将22改成3310即可,然后保存退出:wq!
           service iptables restart
           然后用Navicat连接
