##### 1. 安装Mysql需要的依赖包
```bash
bash-4.3 ~# yum -y install ncurses-devel libaio-devel cmake
bash-4.3 ~# rpm -qa ncurses-devel libaio-devel cmake
libaio-devel-0.3.107-10.el6.x86_64
ncurses-devel-5.7-4.20090207.el6.x86_64
cmake-2.8.12.2-4.el6.x86_64
```
##### 2. 开始安装MySQL(5.6/30)
 - 2.1 创建用户和组

```bash
bash-4.3 ~# useradd -M -s /sbin/nologin mysql
```
 - 2.2 安装MySQL

```bash
bash-4.3 ~# cd /usr/local/src
bash-4.3 src# wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.30.tar.gz
bash-4.3 src# tar zxf mysql-5.6.30.tar.gz
bash-4.3 src# cd mysql-5.6.30
bash-4.3 mysql-5.6.30# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql-5.6 \        <- MySQL安装路径

- 2.3 创建MySQL多实例的数据文件目录(3306, 3307)

```bash
bash-4.3 mysql-5.6.30# mkdir -p /data/{3306,3307}/data
bash-4.3 mysql-5.6.30# tree /data
/data
├── 3306            <- 3306实例的目录
│   └── data        <- 3306实例的数据文件目录
├── 3307            <- 3307实例的目录
│   └── data        <- 3307实例的数据文件目录
```

- 2.4 创建数据库(3306, 3307)配置文件

- 2.5 多实例启动和停止命令

```bash
### 启动命令
bash-4.3 mysql-5.6.30# /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/3306/my.cnf 2>&1 > /dev/null &
bash-4.3 mysql-5.6.30# /usr/local/mysql/bin/mysqld_safe --defaults-file=/data/3307/my.cnf 2>&1 > /dev/null &
### 停止命令
bash-4.3 mysql-5.6.30# /usr/local/mysql/bin/mysqladmin -uroot -p -S /data/3306/mysql.sock shutdown
bash-4.3 mysql-5.6.30# /usr/local/mysql/bin/mysqladmin -uroot -p -S /data/3307/mysql.sock shutdown
bash-4.3 mysql-5.6.30# chown -R mysql:mysql /data/      <- 更改/data目录权限
```

- 2.6 配置MySQL命令全局使用路径

```bash
### 以下两种方法都可以
bash-4.3 mysql-5.6.30# ln -s /usr/local/mysql/bin/* /usr/local/sbin/
bash-4.3 mysql-5.6.30# echo "export PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile
bash-4.3 mysql-5.6.30# source /etc/profile
```

- 2.7 初始化数据库

```bash
bash-4.3 mysql-5.6.30# cd /usr/local/mysql/scripts/
bash-4.3 scripts# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/data/3306/data/ --user=mysql
bash-4.3 scripts# echo $?
0
bash-4.3 scripts# ./mysql_install_db --basedir=/usr/local/mysql --datadir=/data/3307/data/ --user=mysql
bash-4.3 scripts# echo $?
0
bash-4.3 scripts# netstat -anpt|grep mysql
tcp        0      0 0.0.0.0:3306                0.0.0.0:*                   LISTEN      1341/mysqld
tcp        0      0 :::3307                     :::*                        LISTEN      13637/mysqld 
```

- 2.8 进入mysql(3306,3307)数据库

```bash
bash-4.3 scripts# mysql -uroot -p -S /data/3306/mysql.sock

```bash
bash-4.3 scripts# vim /data/3306/mysql

    else
        printf "MySQL is running...\n"
        exit
    fi
}

# Stop function
function_stop_mysql(){

        ${CmdPath}/mysqladmin -u ${mysql_user} -p ${mysql_pwd} -S /data/${port}/mysql.sock shutdown
    fi
}

# Restart function
function_restart_mysql(){
    printf "Restarting MySQL...\n"
    function_stop_mysql
    sleep 2
    function_start_mysql
}

case $1 in
start)
    function_start_mysql
    ;;

    echo "/data/${port}/mysql {start|restart|stop}"
    ;;
esac
