在編譯安裝 MySQL 5.6.x 之前，需要最少安裝的包有：bison,gcc、gcc-c++、cmake、ncurses-devel,
安裝這些依賴包後,把原來解壓出來的mysql源碼目錄刪除掉,再重新解壓出來,再去編譯.

WARNING: The host 'mysql.yest.nos' could not be looked up with /usr/local/mysql56/bin/resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/local/mysql56/bin/mysqladmin -u root password 'new-password'
/usr/local/mysql56/bin/mysqladmin -u root -h mysql.yest.nos password 'new-password'
Alternatively you can run:
/usr/local/mysql56/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; /usr/local/mysql56/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems with the ./bin/mysqlbug script!

New default config file was created as /usr/local/mysql56/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

【PS】半同步復制
-- =================================================================
MySQL AB復制原理：
Master 服務器 （主服務器） 通過把所有涉及到數據庫更新操作都記錄到二進制日志當中，
然後Slave 服務器（從服務器）就會通過IO_THREAD線程如連接主服務器，然後主服務器會通過IO_THREAD應答從服務器，然後開始傳輸二進制日志。從服務器接受到相應的日志記錄之後，就會通過SQL_THREAD線程去執行日志當中記錄的更改.
實現的級別：row level,statement level,mixed level
復制時延性：異步復制（MySQL AB復制天然屬性），實時復制（MySQL + DRBD），半同步復制（>=5.5版本之後才有，暫時不算完善）
1、安裝半同步復制的模塊
master> install plugin rpl_semi_sync_master soname 'semisync_master.so'; 參數rpl_semi_sync_master_enabled=1 才生效。如果在安裝的時候不注釋掉，會報unknown variable 'rpl_semi_sync_master_enabled=1'的錯誤。
slave1> install plugin rpl_semi_sync_slave soname 'semisync_slave.so';
2、激活半同步復制
master> set global rpl_semi_sync_master_enabled = on;
slave> set global rpl_semi_sync_slave_enabled = on;
slave> stop slave IO_THREAD;
slave> start slave IO_THREAD;
master> show status like ‘rpl_semi_sync_master_status’;
+—————————–+——-+
| Variable_name | Value |
+—————————–+——-+
| Rpl_semi_sync_master_status | ON |
+—————————–+——-+
master> show status like ‘rpl_semi_sync_master_clients’;
+——————————+——-+
| Variable_name | Value |
+——————————+——-+
| Rpl_semi_sync_master_clients | 1 | <---說明一個從服務器是使用半同步模式
+------------------------------+-------+
3、確定正在使用半同步模式
master> insert into user values (8,’moto’);
master> show status like ‘Rpl_semi_sync_master_yes_tx’;
+—————————–+——-+
| Variable_name | Value |
+—————————–+——-+
| Rpl_semi_sync_master_yes_tx | 1 | <– 數值代表有多少個事務被從服務器確認
+—————————–+——-+
驗證：
關閉master的網絡，然後提交更新數據，發現會等待10秒才返回，因為主服務器在等待從服務器的確認，10秒之後超時，就會返回，主服務器會恢復到異步模式。
