Fifth Step: Configure slave How to synchronize master's data     //reference command: change Master to Maste R_host= ' 192.168.5.10 ', master_user= ' slave ', master_password= ' slave ', master_port=3306, master_log_file= ' Master_ Bin.000001 ', master_log_pos=120;
Sixth: Open the features of the slave server //reference command: start slave;

4 . View slave sync status //reference command:show slave Status\g

MySQL Master configuration complete

Iv. installation Amoeba: dependent on the Java environment

Java installation
1. Installation

2. Grant amoeba a MySQL remote account
Mysql> GRANT All privileges on * * to ' amoeba ' @ ' 192.168.5.30 ' identified by ' amoeba ' with GRANT OPTION;

V. Installation of Amoeba:

Six, configuration:
1, configuration amoeba under the Dbservers.xml

2, configuration amoeba under the Amoeba.xml

Seven, start amoeba:
1, "It is best to start with the current mode, to see if there are errors in startup, after troubleshooting errors in the background start"
Some information on the Internet: JDK7 startup has minimum requirements for XSS parameters and must be greater than 228 to start the JVM
Solve:
Set-xss256k to resolve

1 #JVM_OPTIONS ="-server-xms256m-xmx1024m-xss196k-xx:permsize=16m-xx:maxpermsize=96m " 2 jvm_options="-server-xms1024m-xmx1024m-xss256k-xx:permsize=16m-xx:maxpermsize=96m "

# vim/usr/local/amoeba/jvm.properties

2, Start again: report the error, please see

3, as shown: I did not use the normal shutdown mode to shut down the amoeba service caused by the error
And then, after the kill process, you don't hold a mistake.
So this is a long lesson.
Close Amoeba:
#/usr/local/amoeba/bin/shutdown
Background boot and save the output log to/var/log/amoeba.log
#/usr/local/amoeba/bin/launcher >/var/log/amoeba.log 2>&1 &

Eight, landing test:
1, because there is no MySQL installed on the 30 machine, so find a machine equipped with MySQL to test
MYSQL-UAMOEBA-P123456-H192.168.0.251-P8066//specifies that the port's-p is uppercase and not equal to the other. Be sure to pay attention to casing

2. Successful landing, please test freely.
Test method: (1) Amoeba create the library and then log in to master, slave to see if there are any libraries you just created
(2) Stop master MySQL, and then slave on the creation of the library, cannot indicate success
(3) There are better testing methods on the Internet, not listed. Please find it yourself.
Nine, Amoeba+mysql master-Slave separation configuration is complete!
