解压包 安装mysql配置工具camke ：
tar xf mysql-5.6.4-m7.tar.gz
tar xf cmake-2.8.5.tar.gz
cd cmake-2.8.5
./configure
gmake
gmake install
开始安装mysql ：
cd ../mysql-5.6.4-m7
cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DSYSCONFDIR=/etc -DMYSQL_USER=mysql \

make && make install
多实例开始配置：
cd /usr/local/mysql/data/
mkdir -p {3306,3307,3308}/data #创建实例数据库目录
chown -R mysql.mysql /usr/local/mysql/ #授权目录权限为mysql 用户
ln -s /usr/local/mysql/bin/* /usr/local/sbin/ #mysql相关命令软连接
cd /usr/local/mysql/support-files/
cp my-small.cnf ../data/3306/ #拷贝配置文件到实例主目录下面
cp my-small.cnf ../data/3307/
cp my-small.cnf ../data/3308/
更名配置文件：
cd ../data/3306
mv my-small.cnf my.cnf
cd ../3307
mv my-small.cnf my.cnf
cd ../3308
mv my-small.cnf my.cnf
初始化数据库：
/usr/local/mysql/scripts/mysql_install_db –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data/3306 –defaults-file=/usr/local/mysql/data/3306/my.cnf –user=mysql
/usr/local/mysql/scripts/mysql_install_db –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data/3307 –defaults-file=/usr/local/mysql/data/3307/my.cnf –user=mysql
/usr/local/mysql/scripts/mysql_install_db –basedir=/usr/local/mysql –datadir=/usr/local/mysql/data/3308 –defaults-file=/usr/local/mysql/data/3308/my.cnf –user=mysql
过程中需要看到 有两个OK, 说明就是初始化成功了。如有其它报错请检查权限或者百度。
修改配置文件：
vim /usr/local/mysql/data/3306/my.cnf
vim /usr/local/mysql/data/3307/my.cnf
vim /usr/local/mysql/data/3308/my.cnf
配置文件内容 （基本相同，只需要修改端口，和server-id ，目录文件名称对应即可）
[client]
port = 3306
socket = /usr/local/mysql/data/3306/mysql.sock
[mysqld]

启动实例：
mysqld_safe –defaults-file=/usr/local/mysql/data/3306/my.cnf &
mysqld_safe –defaults-file=/usr/local/mysql/data/3307/my.cnf &
mysqld_safe –defaults-file=/usr/local/mysql/data/3308/my.cnf &
查看端口状态：
[[email protected] mysql]# netstat -anpt|grep 330
tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 36275/mysqld
tcp 0 0 0.0.0.0:3308 0.0.0.0:* LISTEN 36283/mysqld
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 36328/mysqld
测试进入数据库：
mysql -uroot -S /usr/local/mysql/data/3306/mysql.sock
关闭mysql数据库实例：
mysqladmin -uroot -S /usr/local/mysql/data/3306/mysql.sock shutdown
mysqladmin -uroot -S /usr/local/mysql/data/3307/mysql.sock shutdown
mysqladmin -uroot -S /usr/local/mysql/data/3308/mysql.sock shutdown
为mysql实例设置密码：
mysqladmin -uroot -S /usr/local/mysql/data/3306/mysql.sock password “root”
mysqladmin -uroot -S /usr/local/mysql/data/3307/mysql.sock password “root”
mysqladmin -uroot -S /usr/local/mysql/data/3308/mysql.sock password “root”
设置密码后 进入数据库：
mysql -uroot -proot -S /usr/local/mysql/data/3306/mysql.sock
mysql -uroot -proot -S /usr/local/mysql/data/3307/mysql.sock
mysql -uroot -proot -S /usr/local/mysql/data/3308/mysql.sock
设置密码后 停止mysql数据实例：
mysqladmin -uroot -S /usr/local/mysql/data/3306/mysql.sock shutdown -proot
mysqladmin -uroot -S /usr/local/mysql/data/3307/mysql.sock shutdown -proot
mysqladmin -uroot -S /usr/local/mysql/data/3308/mysql.sock shutdown -proot
