阿新 • • 發佈:2019-03-13
安裝
sudo apt-get install mysql-server mysql-client
未出現錯誤則安裝完成。
修改相關配置及root密碼
配置遠端連線
修改 /etc/mysql/mysql.conf.d/mysqld.cnf
配置檔案,找到 bind-address
,修改如下:
# # 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 # 允許遠端連線 bind-address = 0.0.0.0
授權 root
遠端連線,執行下列sql:
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION; FLUSH PRIVILEGES; mysql> select host, user, authentication_string from user; +-----------+------------------+-------------------------------------------+ | host | user | authentication_string | +-----------+------------------+-------------------------------------------+ | localhost | root | | | localhost | mysql.session | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | localhost | mysql.sys | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | | localhost | debian-sys-maint | *42276B9FD61650D300927D4A0A6EFFA93BBFD11D | | % | root | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B | +-----------+------------------+-------------------------------------------+ 5 rows in set (0.00 sec)
修改字符集
在 /etc/mysql/conf.d/mysql.cnf
配置檔案,新增如下:
[mysql]
default-character-set=utf8
在 /etc/mysql/mysql.conf.d/mysqld.cnf
配置檔案,新增如下:
[mysqld]
character-set-server=utf8
檢視:
mysql> show variables like '%character%'; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.01 sec)
修改root密碼
使用 mysqladmin
sudo mysqladmin -u root password newpassword

sudo service mysql restart
嘗試遠端連線:
➜ ~ mysql -h192.168.8.106 -uroot -p
