一：官网下载mysql二级制包。

1：官网下载一个MySQL二级制包，下载到/opt/mysql 目录下

Cd /opt/mysql

wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.16-linux-glibc2.5-x86_64.tar.gz

二：mysql二级制包解压。

Cd /opt/mysql

tar -zxvf  mysql-5.7.16-linux-glibc2.5-x86_64.tar.gz

三：设置mysql库文件路径与授权

1.  创建mysql软链接：

cd /usr/local

ln -s /opt/mysql/mysql-5.7.16-linux-glibc2.5-x86_64  mysql

2.  创建mysql运行的用户

groupadd mysql

useradd -g mysql -d /usr/local/mysql -s /sbin/nologin -M -n mysql

3. 创建mysql数据库库文件目录

mkdir -p /data/mysql/3306/{data,logs,tmp}

4.给目录授权mysql用户

chown -R mysql:mysql /data/mysql/3306/

chown -R mysql:mysql /usr/local/mysql/

四. 创建配置文件

 vim  /data/mysql//my.cnf

#my.cnf

[client]

port            = 

socket          =  /tmp/mysql3306.sock

[mysql]

prompt="\\u@\\h:\\p [\\d]>"

#pager="less -i -n -S"

#tee=/data/mysql//query.log

no-auto-rehash

[mysqld]

#misc

user = mysql

basedir = /usr/local/mysql

五：数据库初始化

/usr/local/mysql

./bin/mysqld --defaults-file=/data/mysql/3306/my.cnf --basedir=/usr/local/mysql --datadir=/data/mysql/3306/data --user=mysql --initialize

[注意： ./bin/mysqld --initialize-insecure     密码为空]

查看初始化后随即生产的root@localhost密码

[root@yelj-centos7 ~]# cat /data/mysql/3306/data/error.log |grep "root@localhost"|awk -F " " '{print $11}'

D,wSi#<ad9Ij

六： 设置mysql变量

echo "export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile

七： MySQL启动

/usr/local/mysql/bin/mysqld  --defaults-file=/data/mysql/3306/my.cnf &

以下两种可以加入开机启动

chkconfig add mysql

echo “/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &” >>/etc/rc.local

八：快速创建实例

快速创建一个实例3307

3307

cd  /data/mysql

cp –rp 3306 3307

cd 3307

sed -i 's/3306/3307/g' my3307.cnf

创建启动脚本

Echo “/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/3307/my.cnf &” > start.sh

九：关闭mysql服务

/usr/local/mysql/bin/mysqladmin –uroot –p –S /tmp/mysql3306.sock  shutdown
