ubuntu server配置mysql并实现远程连接的操作方法

发布时间:2018-04-15 10:09:20   

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

# 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”);

# 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

# 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

8 rows in set (0.00 sec)

新建远程登录用户并授权

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:

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

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

重启服务器

# 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

# eric @ ray in ~ [14:37:13] C:1
$ mysql -h 192.168.122.58 -u eric -p #
Enter password:

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");
