記MySQL在Ubuntu(18.04.1 LTS)的安裝

本文記錄一次在Ubuntu(18.04.1 LTS)上安裝MySql過程,安裝後的mySQL版本為5.7.24。

安裝環境
[email protected]~virtual-machine:/etc# cat /etc/issue
Ubuntu 18.04.1 LTS
安裝mySql

以下為按照命令,在提示需要輸入 [Y/n] 時,輸入Y.

[email protected]~virtual-machine:~# sudo apt-get install mysql-server
[email protected]~virtual-machine:~# sudo apt-get install mysql-client
[email protected]~virtual-machine:~# sudo apt-get install libmysqlclient-dev [email protected]~virtual-machine:~#

安裝完成後,進入mySql

[email protected]~virtual-machine:~# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

修改mysqld.cnf配置並重啟MySQL服務

在安裝好後,需要修改MySQL配置,否則其他的資料電腦或虛擬機器不能連線該MySQL服務。在/etc/mysql/mysql.conf.d/mysqld.cnf裡面,注掉或者刪掉bind-address = 127.0.0.1”,或者將bind-address = 127.0.0.1修改為“bind-address = 0.0.0.0”。

[email protected]~virtual-machine:~# vi /etc/mysql/mysql.conf.d/mysqld.cnf
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
# bind-address           = 127.0.0.1

bind-address修改後,需要重啟mySQL服務。

[email protected]~virtual-machine:~# service mysql restart

通過Navicat 或者SQL Developer工具連線

在以上步驟完成後,可以通過Navicat或SQL Developer工具連線到已安裝的MySQL。此處使用SQL Developer連線到安裝的MySQL。

連線名(M):自己定義 使用者名稱(U):該值為前面建立的使用者user 口令(P):該值為前面建立的密碼password 主機名(A):主機名為MySQL安裝的地址 埠(R):埠為MySQL服務監聽埠 在這裡插入圖片描述
