************************************************************
         CentOS6.5_64bit下编译安装MySQL-5.6.23 
**************************************************************
一、关闭防火墙
chkconfig iptables off 
service iptables stop

二、下载mysql源代码包。mysql-5.6.23.tar.gz 
下载时注意别选成其它的linux安装包。不然编译肯定报错。选择平台的下拉列表里选择 Source Code，Select Platform: Source Code ，
下载 Generic Linux (Architecture Independent), Compressed TAR Archive。

三、加入用户和组:
groupadd  mysql #添加用户组
useradd -g mysql mysql -s /usr/sbin/nologin

四、创建文件夹及授权
mkdir -p /u01/my3306/data            #mysql数据文件夹
mkdir -p /u01/my3306/log/iblog            #mysql innodb日志
mkdir -p /u01/my3306/log/binlog           #mysql日志
mkdir -p /u01/my3306/log/relaylog
mkdir -p /u01/my3306/run
mkdir -p /u01/my3306/tmp
chown -R mysql:mysql /u01/my3306
chmod -R 755 /u01/my3306

五、解压
tar -zxvf mysql-5.6.23.tar.gz 
cd mysql-5.6.23

六、编译并安装
cmake \
-DCMAKE_INSTALL_PREFIX=/u01/my3306 \
-DINSTALL_DATADIR=/u01/my3306/data  \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=all \
-DWITH_SSL=yes \
-DWITH_EMBEDDED_SERVER=1 \
-DENABLED_LOCAL_INFILE=1 \

-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DMYSQL_TCP_PORT=3306 \
-DENABLED_LOCAL_INFILE=1 \
-DSYSCONFDIR=/etc \
-DWITH_READLINE=on

make
make install

七、改动配置文件my.cnf參数
cp /u01/my3306/support-files/my-default.cnf  /u01/my3306/my.cnf

vi   /u01/my3306/my.cnf   ---加入

[client]
port = 3306
socket =/u01/my3306/run/mysql.sock

[mysql]

innodb_support_xa=1

[mysqld_safe]
datadir=/u01/my3306/data/

八、运行MySQL安装脚本
./scripts/mysql_install_db  --defaults-file=/u01/my3306/my.cnf  --user=mysql --datadir=/u01/my3306/data
    
说明:defaults-file表示指定默认的配置文件，假设不指定。系统默认的优先级是先使用/etc/my.cnf作为mysql的配置文件，那之前make的那些參数就白设置了.

九、启动mysql
mysqld_safe --defaults-file=/u01/app/mysql/data/mysql3306/my.cnf --user=mysql &

十、登录MySQL
mysql -h127.0.0.1 -uroot -P3306
