Windows安裝配置Mycat

第一步，安裝JDK並配置環境變量

第二步，安裝MySQL

第三步，創建mycat數據庫並創建user表

添加一條數據

第四步，下載Mycat

下載地址：https://github.com/MyCATApache/Mycat-download

我下載的版本是1.5

第四步，解壓壓縮包，最好放到沒有中文路徑的目錄

第五步，安裝mycat，使用管理員身份打開cmd，進入D:/mycat/bin目錄

執行mycat.bat install命令

第六步，配置用戶信息，打開conf文件夾下的server.xml

添加testuser用戶，它只可以訪問testmycat庫

第七步，配置數據庫信息，打開conf文件夾下的schema.xml

<?xml version="1.0"?>

</mycat:schema>

添加了三個測試的schema、dataNode、dataHost標籤，連接的是本地創建的mycat庫，並配置user表爲全局表。

注意：schema、dataNode、dataHost標籤必須按照順序寫，即

schema

schema

。。。

dataNode

dataNode

。。。

dataHost

dataHost

。。。

否則啓動會報錯。

第八步，配置wrapper.conf 

修改jdk地址

修改jvm參數

如果是jdk8需要修改MaxPermSize爲MaxMetaspaceSize，否則啓動報錯

第九步，啓動mycat

使用管理員身份打開cmd，進入D:/mycat/bin目錄

執行mycat.bat start命令

通過mycat.bat status命令查看狀態

第十步，使用Navicat連接mycat
