MySQL数据库--读写分离时的BUG

问题：在amoeba服务器配置amoeba服务时，netstat -anpt | grep java没有反应，端口没有开启

[root@localhost conf]# netstat -anpt | grep java
[root@localhost conf]# netstat -anpt | grep 8066   

分析原因

• 第一时间，我先想到了是不是我在前面的配置文件中的内容配错了，所以，我首先查看了amoeba服务器的两个配置文件

• amoeba.xml 、 dbServers.xml

解决问题

查看修改配置文件，配置文件的具体内容可以看我之前的‘搭建 MySQL’ 读写分离的amoeba服务器配置amoeba服务（192.168.126.12）部分

vim amoeba.xml	

vim dbServers.xml

结果真的是配置文件错了，vim dbServers.xml 的配置文件里120行的后半个注释没有去除干净 还留了一部分，删掉之后就好了

总结

所以，兄弟们 在配置服务文件时一定要细心，仔细的检查一下，不然就会很费时间和精力的，实在检查不出来就重新做，这样来的还比较快一点
