debain下mysql5.7安裝

1. 首先輸入mysql --version看有沒有安裝過其他版本的mysql，有的話卸載掉

apt-get remove mysql-common
apt-get remove mysql*

2. 下載包並解壓升級

sudo dpkg -i mysql-apt-config_0.8.9-1_all.deb 
sudo apt-get update

若更新過程中出現錯誤：EXPKEYSIG 8C718D3B5072E1F5 MySQL Release Engineering

執行以下操作再次更新就OK

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8C718D3B5072E1F5
sudo apt-get update

3. 安裝mysql

sudo apt-get install mysql-server mysql-common

若是報如下錯：

換成下面源（vi /etc/apt/sources.list），然後再apt-get update

deb http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch main non-free contrib
deb http://mirrors.aliyun.com/debian-security stretch/updates main
deb-src http://mirrors.aliyun.com/debian-security stretch/updates main
deb http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-updates main non-free contrib
deb http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib
deb-src http://mirrors.aliyun.com/debian/ stretch-backports main non-free contrib

再次執行安裝 sudo apt-get install mysql-server mysql-common

4. 啓動mysql5.7

service mysql start

5. 添加訪問權限

vi /etc/mysql/mysql.conf.d/mysqld.cnf

bind-address = 0.0.0.0
