遠端連線ubuntu系統的mysql服務時發生錯誤 error no. 2003 can't connect to mysql server on '10.15.92.131' (10065)
進入終端命令，輸入
nmap localhost -p3306結果為
starting nmap 5.21 ( ) at 2013-01-09 18:04 cst
nmap scan report for localhost (127.0.0.1)
host is up (0.000037s latency).
port state service
3306/tcp open mysql
以訪問的ip的替代localhost
nmap 10.15.92.131 -p3306結果為
starting nmap 5.21 ( ) at 2013-01-09 18:04 cst
nmap scan report for 10.15.92.131
host is up (0.000045s latency).
port state service
3306/tcp closed mysql
兩相對比可以看出直接用ip連線的3306/tcp is closed
之後進入mysql命令列後，檢視登入使用者有無遠端連線的許可權
use mysql
select host,user from user
+------------------------+------------------+
| host | user |
+------------------------+------------------+
| % | lace |
| % | root |
| 10.15.92.131 | root |
| baowp-work-lenovo-b460 | |
| localhost | debian-sys-maint |
+------------------------+------------------+
退出mysql命令列，再編輯mysql的配置檔案my.cnf
sudo vi /etc/mysql/my.cnf修改 bind-address = 127.0.0.1 為 bind-address = 0.0.0.0
最後重啟mysql
sudo /etc/init.d/mysql restart再檢視 nmap 10.15.92.131 -p3306時看到3306/tcp open mysql，此時可以遠端登入
starting nmap 5.21 ( ) at 2013-01-09 18:04 cst
nmap scan report for 10.15.92.131
host is up (0.000045s latency).
port state service
3306/tcp closed mysql
ubuntu12 04 配置mysql允許遠端訪問
首先，修改 etc mysql目錄下面的my.cnf檔案，把其中的bind address設定為你的ip,假設為192.168.0.240 bash bind address 192.168.0.240 bash 我的mysql 版本如下 bash mysql ver 14.14 distrib 5...
