1.解压mysql
tar -xf mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz -C /usr/local
mv mysql-5.6.30-linux-glibc2.5-x86_64 mysql-5.6.30
2.添加用户与组
groupadd mysql
useradd -g mysql mysql -s /sbin/nologin
chown -R mysql:mysql mysql-5.6.30
3.安装数据库
mkdir /usr/local/mysql-5.6.30/data3306
cd mysql-5.6.21/scripts
./mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.6.30/ --datadir=/usr/local/mysql-5.6.30/data3306/
4.配置文件
cd /usr/local/mysql-5.6.30/support-files
cp my-default.cnf /etc/my.cnf
cp mysql.server /etc/init.d/mysql
vim /etc/init.d/mysql
修改文件中的两个变更值

5.配置环境变量
vi /etc/profile
export MYSQL_HOME="/usr/local/mysql-5.6.30"
export PATH="$PATH:$MYSQL_HOME/bin"
6.添加自启动服务
chkconfig mysql on
7.启动mysql
service mysql start
8.登录mysql及改密码
mysqladmin -u root password 'your_password' #修改root用户密码
mysql -u root -p #登录mysql,需要输入密码
