amoeba的部署（mysql讀寫分離，負載均衡）
阿新 • • 發佈：2019-01-01
環境前提：java （負載均衡在主從複製環境下針對從庫池，讀寫分離不需要主從複製，有也需要關掉服務才有測試效果）
amoeba是阿里沿用的mysql中介軟體，
下載包 amoeba-mysql-3.0.5-RC-distribution.zip
解壓到/usr/src/
主要兩個配置檔案 dbServer.xml 控制代理端和邏輯庫池間的關係 amoeba.xml控制amoeba的連線埠和密碼
dbServers.xml 多個數據源，多個數據庫
amoeba.xml 啟動引數，誰負責讀，誰負責寫，誰負責負載均衡

amoeba.xml 的配置如下
[[email protected] ~]# vim /usr/src/amoeba/conf/amoeba.xml
[[email protected] ~]# vim /usr/src/amoeba/conf/amoeba.xml
<amoeba:configuration xmlns:amoeba=“http://amoeba.meidusa.com/”>

</amoeba:configuration>
server1 其實這裡的server1 也可以換成一個地址池名
server2 其實這裡的server2 也可以換成一個地址池名
最後啟動amoeba bin目錄下有個 launcher ./launcher
關於報錯The stack size specified is too small, Specify at least 228kError: Could not create the Java Virtual Machine.Error: A fatal exception has occurred. Program will exit.
vim /root/amoeba/jvm.properties # 修改
JVM_OPTIONS="-server -Xms256m -Xmx1024m -Xss256k…
此時需要測試讀寫分離，需要關掉主從複製
