MySQL proxy middleware atlas installation and configuration

The premise is to configure master-slave reference ：http://www.cnblogs.com/super-d2/p/4802990.html

First , Go ahead and download Altas Of rpm package , Download address ：https://github.com/Qihoo360/Atlas/releases

To see the version clearly ,centos 5.x：Atlas-1.0.3.el5.x86_64.rpm centos 6.x：

My system is centos 6.4 , So download Atlas-1.0.3.el6.x86_64.rpm

Don't get it wrong , Otherwise, an error will occur in the final startup . You can also adopt source code compilation and installation , however rpm Installation is time-saving and labor-saving , And it's simple .

download rpm

wget https://github.com/Qihoo360/Atlas/releases/download/1.0.3/Atlas-1.0.3.el6.x86_64.rpm

Copy

install

rpm -i Atlas-1.0.3.el6.x86_64.rpm

Copy

The installation directory is /usr/local/mysql-proxy

conf There is a configuration file under the folder test.cnf, We can modify it directly , Here is what I modified

Master database server ：192.168.83.11

From the database server ：192.168.83.12

proxy The server ：192.168.83.13

 # Set up Atlas Mode of operation , Set to true Time is the way of daemons , Set to false It's the front desk way , Generally, it is set as false, The online runtime is set to true
daemon = false# Set up Atlas Mode of operation , Set to true when Atlas Will start two processes , One for monitor, One for worker,monitor stay worker It will restart automatically after an unexpected exit , Set to false It's just worker, No, monitor, Generally, it is set as false, The online runtime is set to true
keepalive = false
 # Number of worker threads , Recommended settings and system CPU Auditing is equal event-threads = 4
 # The level of logging , It is divided into message、warning、critical、error、debug The five level 
log-level = message
 
# Log storage path 
log-path = /usr/local/mysql-proxy/log
 
# Instance name , For more than one... On the same machine Atlas The distinction between examples 
instance = test
 
#Atlas Working interface for monitoring IP And port 
proxy-address = 0.0.0.0:1234
 #Atlas Monitoring management interface IP And port 
admin-address = 0.0.0.0:2345# The minimum number of free connections in the connection pool , It should be set to event-threads Integer multiple , It can be appropriately increased or decreased according to the size of business requests 
min-idle-connections = 8
 # Sub table settings , In this case person For the name of the library ,mt Is the name of the watch ,id For the sub table fields ,3 Is the number of sub tables , Multiple items can be set , Separated by commas , If you do not divide the table, you do not need to set this item 
#tables = person.mt.id.3
 # The user name and its corresponding encrypted MySQL password , Password usage PREFIX/bin The encryption program in the directory encrypt encryption , This setting item is used for multiple user names to access the same Atlas Examples , If there is only one user name > You do not need to set this item 
#pwds = user1:+jKsgB3YAG8=, user2:GS+tr4TPgqc=
 # Default character set , If it is not set , The default character set is latin1
charset = utf8
 
# Allow connections Atlas Client side IP, It can be precise IP, It can also be IP paragraph , Separated by commas , If this item is not set, all IP Connect , Otherwise, only... In the list is allowed IP Connect 
#client-ips = 127.0.0.1, 192.168.1
 #Atlas It's on the front LVS Of the physical network card IP( Notice that it's not empty IP), If you have any LVS And set up client-ips Then this item must be set , Otherwise, you can not set 
#lvs-ips = 192.168.1.1 Last , Enter into bin Under the folder , start-up Altas

Copy

./mysql-proxy --defaults-file=../conf/test.cnf

Copy

It is best to configure the daemon Set to true, Run for background daemon .

Using the official website

./mysql-proxydteststart

see Altas Operation of the

./mysql-proxyd test status

There are two processes .

I later used NaviCat Connect work port , The user name and password are the administrative user and password of the above configuration file , succeed .

After testing ,Altas The read-write separation and transaction support are very good , Release tomorrow 2.0 edition , Add to JDBC Support for .
