2 解壓

root用戶登陸，上傳安裝包到服務器
cd /opt
rz
解壓
tar -xvf mysql-5.6.41-linux-glibc2.12-x86_64.tar
複製解壓後的mysql目錄
cd mysql-5.6.41-linux-glibc2.12-x86_64

mkdir /usr/loacl/mysql

cp -r ./* /usr/local/mysql

3 添加用戶組和用戶

添加用戶組
groupadd mysql
添加用戶mysql到用戶組
useradd -g mysql mysql

4 安裝

cd /usr/local/mysql
chown -R mysql:mysql ./
./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
cp support-files/mysql.server /etc/init.d/mysql
cp support-files/my-default.cnf /etc/my.cnf    

vi /etc/my.cnf

修改：

basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
port=3306
server_id=1
socket=/tmp/mysql.sock

添加：

character_set_server=utf8

加入環境變量，編輯 /etc/profile，這樣能夠在任何地方用mysql命令了

export PATH=$PATH:/usr/local/mysql/bin
source /etc/profile

啓動mysql
service mysql start

修改root密碼

mysqladmin -u root password '123456'

測試鏈接
mysql -u root -p
關閉mysql
service mysql stop
查看運行狀態
service mysql status

開機自啓動配置
chkconfig --add mysql
chkconfig --list
chkconfig --level 345 mysql on

容許全部外部連接訪問

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
FLUSH PRIVILEGES;
