在Linux中安裝MySql數據庫

在Linux中安裝MySql數據庫

1. 上傳安裝包

將rpm包上傳到/root/work目錄(也可以是其他目錄)
MySQL-server-5.6.29-1.linux_glibc2.5.x86_64.rpm
MySQL-client-5.6.29-1.linux_glibc2.5.x86_64.rpm

2. 刪除系統自帶mysql

#查看之前是否安裝過mysql
rpm -qa | grep -i mysql
#如果安裝過，執行這行代碼，刪除之前安裝過的mysql
rpm -ev --nodeps mysql-libs-5.1.71-1.el6.x86_64

3. 增加用戶組

#增加用戶組mysql
groupadd mysql
#增加用戶mysql，加入mysql用戶組
useradd -r -g mysql mysql

4. 安裝

#安裝server
rpm -ivh MySQL-server-5.6.29-1.linux_glibc2.5.x86_64.rpm
#安裝client
rpm -ivh MySQL-client-5.6.29-1.linux_glibc2.5.x86_64.rpm

[mysqld]
character_set_server=utf8

cp /usr/share/mysql/mysql.server /etc/init.d/mysqld

7. 啓動服務

8. 修改root默認密碼

#獲取mysql安裝時root用戶的隨機密碼
vim /root/.mysql_secret
#必須要修改root用戶的密碼纔可以使用mysql，否則只能連接不能操作
mysqladmin -u root -p password root
