ubuntu server配置mysql并实现远程连接的操作方法

服务器：ubuntu server 16.04 LSS

客户机：ubuntu 16.04 LTS

服务器配置

服务器安装mysql

?

1 2	# eric @ userver in ~ [14:00:31] $ sudo apt install mysql-server install mysql-client libmysqlclient-dev

检查是否成功SET PASSWORD FOR ‘pig'@'%' = PASSWORD(“123456”);

?

1 2 3

# eric @ userver in ~ [14:10:55] $ sudo netstat -tap | grep mysql tcp 0 0 localhost:mysql *:* LISTEN 5287/mysqld

修改远程连接配置文件

?

1 2 3 4

# eric @ userver in ~ [14:16:26] $ sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf #注释掉 bind-address   = 127.0.0.1 #bind-address   = 127.0.0.1

设置服务器数据库字符为utf-8

?

# eric @ userver in ~ [14:16:26] $ sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf #在[mysqld] 中添加：character-set-server=utf8 [mysqld] # # * Basic Settings # user   = mysql pid-file  = /var/run/mysqld/mysqld.pid socket   = /var/run/mysqld/mysqld.sock port   = 3306 basedir   = /usr datadir   = /var/lib/mysql tmpdir   = /tmp lc-messages-dir = /usr/share/mysql skip-external-locking character-set-server=utf8 #新增加   #登录mysql查看字符   # eric @ userver in ~ [14:21:26] $ mysql -u root -p Enter password: Welcome to the MySQL monitor.

新建远程登录用户并授权

?

1 2 3 4

mysql> create user 'eric'@'%' identified by 'lyd2017'; Query OK, 0 rows affected (0.01 sec) mysql> grant all on *.* to 'eric'@'%';--所有权限 Query OK, 0 rows affected (0.00 sec)

关于授权：

命令：GRANT privileges ON databasename.tablename TO 'username'@'host'

说明：privileges-用户的操作权限，如select，insert,update 等，如果要授予所有权则使用all

如果要授予该用户对所有数据库和表的操作权限则用* 表示，如 *.*

例如：

?

1 2	GRANT SELECT, INSERT ON mysql.tables TO 'eric'@'%'; GRANT ALL ON *.* TO 'eric'@'%';

但是用这些命令授权的用户不能再给其他用户授权，如果要让该用户有权限，则使用

?

1	GRANT privileges ON databasename.tablename TO 'username'@'host' WITH GRANT OPTION;

重启服务器

?

1 2 3 4 5 6 7

# eric @ userver in ~ [14:35:49] $ /etc/init.d/mysql restart [....] Restarting mysql (via systemctl): mysql.service==== AUTHENTICATING FOR org.freedesktop.systemd1.manage-units === Authentication is required to restart 'mysql.service'. Authenticating as: eric,,, (eric) Password: ==== AUTHENTICATION COMPLETE ===

客户端

安装mysql客户端

?

# eric @ ray in ~ [14:32:12] C:127 $ sudo apt install mysql-client [sudo] password for eric: Reading package lists... Done

连接mysql服务器

?

1 2 3 4 5 6 7 8 9 10 11 12

# eric @ ray in ~ [14:37:13] C:1 $ mysql -h 192.168.122.58 -u eric -p # Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

关于直接用root用户连接报错问题

?

# eric @ ray in ~ [14:35:22] C:1 $ mysql -h 192.168.122.58 -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'192.168.122.1' (using password: YES)   #如果刚开始，直接用root用户登录，则会报错，可修改root密码解决该问题 mysql>SET PASSWORD FOR 'root'@'%' = PASSWORD("123456");
