Ubuntu下安装与远程连接
安装、查看服务、服务是否随开机自动启动、查看端口、本地连接、远程连接。
5.7
安装
apt install mysql-server //默认安装5.7，密码比如ABCabc123456789
查看服务
ll /etc/init.d
-rwxr-xr-x 1 root root 5607 2月 4 2017 mysql*
service mysql status

显然，安装后自动启动服务。
服务是否随开机自动启动
reboot
显然，mysql服务随开机自动启动。
查看端口
netstat -anpl|grep mysql
tcp6 0 0 :::3306 :::* LISTEN 1135/mysqld
本地连接
远程连接
1 添加无IP限制用户
mysql -uroot -p //本地连接。
mysql> use mysql;
mysql> select host,user from user;
mysql> create user 'root'@'%' identified with mysql_native_password by 'ABCabc123456789';
mysql> grant all privileges on *.* to 'root'@'%';
mysql> show grants for 'root'@'%';
mysql> exit
2 修改配置文件。
# cat /etc/mysql/my.cnf
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
# vim /etc/mysql/mysql.conf.d/mysqld.cnf
# bind-address = 127.0.0.1 //这一行注释掉或者是修改成=0.0.0.0
3 重启服务（视情形是否必要）。
/etc/init.d/ mysql restart
4 防火墙开放端口（视情形是否必要）。
iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 3306 -j ACCEPT
8.0
安装方式：apt、二进制包、源码编译。
以apt为例
安装 ABCabc123456789
wget https://repo.mysql.com//mysql-apt-config_0.8.10-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.10-1_all.deb
sudo apt update
sudo apt install mysql-server //use legacy authentication method (retain mysql 5.x compatibility)
查看服务
ll /etc/init.d
