amoeba mysql的安裝配置實例

Amoeba是一個以MySQL為底層數據存儲，並對應用提供MySQL協議接口的proxy。它集中地響應應用的請求，依據用戶事先設置的規則，將SQL請求發送到特定的數據庫上執行，下面我們來看看amoeba mysql的安裝配置教程。

1、配置好mysql的主從環境，服務器如下：

 代碼如下 復制代碼

master:172.16.206.129
slave:172.16.206.130
amoeba:172.16.206.131

2、amoeba配置好JDK環境

可以去oracle的官網去下載JDK，安裝目錄一邊不是標准的命名，使用如下命令做軟連接：
ln -s /usr/java/jdk1.8.0_11/ /usr/java/jdk1.8
配置JDK環境：
在/etc/profile文件末尾添加以下環境參數

 代碼如下 復制代碼 export JAVA_HOME=/usr/java/jdk1.8
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

PS：下載的JDK需要和平台對應，uname 可以查看平台類型

3、下載amoeba

網上搜索可以去一些開源軟件的網站下載

4、安裝amoeba

安裝路徑/usr/local/amoeba

5、修改amoeba配置參數

/usr/local/amoeba/conf/amoeba.xml 修改如下：

 代碼如下 復制代碼 1 <?xml version=”1.0″ encoding=”gbk”?>

7 Each dbServer needs to be configured into a Pool,
8 If you need to configure multiple dbServer with load balancing that can be simplified by the following configuration:
9 add attribute with name virtual = “true” in dbServer, but the configuration does not allow the element with name factoryConfig
10 such as ‘multiPool’ dbServer

啟動amoeba
/usr/local/amoeba/bin/launcher &

關閉amoeba
/usr/local/amoeba/bin/shutdown
amoeba不支持存儲過程、不支持大數據量查詢，這個比較討厭，所以我最後還是沒有用amoeba
