1.ubuntu下安装mysql需要一些命令
(1)sudo apt-get install mysql-server
安装过程中会出现如下窗口,需要用户输入相关的数据库密码:
(2)sudo apt-get isntall mysql-client
(3)sudo apt-get install libmysqlclient-dev
安装完成之后,可以用下面的命令检查是否安装成功
sudo netstat -tap | grep mysql
通过上述命令检查之后,如果看到有mysql 的socket处于 listen 状态则表示安装成功。
tcp 0 0 localhost:mysql *:* LISTEN 28385/mysqld
2.登陆mysql可以输入如下命令:
mysql -u root -p
show databases;
show tables;
3.补充一些安装过程中的小知识
1. 删除mysql
sudo apt-get autoremove --purge mysql-server-5.0
sudo apt-get remove mysql-server
sudo apt-get autoremove mysql-server
sudo apt-get remove mysql-common (非常重要)
上面的其实有一些是多余的,建议还是按照顺序执行一遍
2. 清理残留数据
dpkg -l |grep ^rc|awk'{print $2}' |sudoxargs dpkg -P
3.ubuntu下启动/停止/重启 mysql
3.1使用service:
sudo service mysql stop
sudo service mysql start
sudo service mysql restart
3.2使用 mysqld 脚本启动
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start
sudo /etc/init.d/mysql restart
重启提示错误如下:
Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service mysql start...
其实已经告诉怎么做了:用sudo service mysql start启动即可
