1.從官網下載MySQL5.6.39壓縮包

2.進行解壓使用 

tar -zxvf MySQL-5.6.39-1.el7.x86_64.rpm-bundle.tar

3.解壓出來有7個檔案，需要安裝只有3個分別是client、devel和server

rpm -ivh MySQL-client-5.6.39-1.el7.x86_64.rpm

rpm -ivh MySQL-devel-5.6.39-1.el7.x86_64.rpm 

rpm -ivh MySQL-server-5.6.39-1.el7.x86_64.rpm

4.複製my-default.cnf到/etc目錄下

cp /usr/share/mysql/my-default.cnf /etc/my.cnf
 

5.初始化並執行資料庫

/usr/bin/mysql_install_db

service mysql start

6.MySQL5.6.39安裝完成後檢視密碼並修改

cat /root/.mysql_secret

mysql -u username -p password 

SET PASSWORD = PASSWORD('yourpassword');

7.允許遠端登入

use mysql;

update user set host='%' where user='root' and host='localhost';

flush privileges;

exit;

8.設定開機啟動

chkconfig mysql on
 

chkconfig --list | grep mysql

mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

9.修改字符集

[client]   
port=3306  
default-character-set=utf8  
[mysqld]  
port=3306  
character_set_server=utf8  
character_set_client=utf8  
collation-server=utf8_general_ci  
#(注意linux下mysql安裝完後是預設：表名區分大小寫，列名不區分大小寫； 0：區分大小寫，1：不區分大小寫)  
lower_case_table_names=1  
#(設定最大連線數，預設為 151，MySQL伺服器允許的最大連線數16384; )  
max_connections=200
[mysql]  
default-character-set = utf8
 

other

（1）預設安裝位置資訊

/var/lib/mysql/            #資料庫目錄
/usr/share/mysql           #配置檔案目錄
/usr/bin                   #相關命令目錄
/etc/init.d/mysql          #啟動指令碼
