1.user.json需要注意的地方

 [root@iZ2ze66bhrbxkc31nljgjnZ cetus_rw]# more conf/users.json
 {
         "users": [{
                         "user": "appuser1",         ----应用用户
                         "client_pwd": "123",        ----client用户
                         "server_pwd": "ESBecs00"    ----链接mysql数据库的用户
                 }, {
                         "user": "devuser",
                         "client_pwd": "123",
                         "server_pwd": "ESBecs00"
                 }]
 }

2.proy.conf需要注意的地方

 [root@iZ2ze66bhrbxkc31nljgjnZ cetus_rw]# more conf/proxy.conf
 [cetus]
 daemon = true

 # Loaded Plugins
 plugins=proxy,admin

 # Proxy Configuration
 proxy-address=127.0.0.1:1234                            ----proxy端口，
 proxy-backend-addresses=47.93.243.162:3306
 proxy-read-only-backend-addresses=47.93.243.162:3308    ---mysql后端

 # Admin Configuration
 admin-address=127.0.0.1:5678                            -----管理端口
 admin-username=admin
 admin-password=admin

 # Backend Configuration
 default-db=test
 default-username=appuser1                               -----默认用户（必须是user里面的）

 # File and Log Configuration
 log-file=cetus.log
 log-level=debug

测试应用端

 [root@iZ2ze66bhrbxkc31nljgjnZ ~]# mysql -uappuser1 -p123 -P1234 -h127.0.0.1 devops
