[SOLVED] Mysql in a different host inaccessible I am following Falko's wonderful tutorial: 1) http://www.howtoforge.com/kvm-and-openvz-virtualization-and-cloud-computing-with-proxmox-ve to create VEs, and 2) http://www.howtoforge.com/perfect-server-debian-lenny-ispconfig3 to install different services in the different VEs. eg. a) VE101 hosts web services like http, ftp (netftp), 1st dns and ispconfig3 (a wonderful product b) VE102 hosts db services like mysql c) VE103 hosts mail services like postfix, courier, squirrelmal/roundcube d) VE104 hosts 2nd dns server 5) VE105 hosts a telephone server Installation of web, ftp and dns services were successful except quota (as there is nothing in VE1's /etc/fstab under openvz???), but when I try to install ispconfig3 in VE101, I could not access the db server in VE102 to create the dbispconfig database with an error message: Code: Unable to connect to mysql server Host '192.168.1.101' is not allowed to connect to this MySQL server I tried to open mysql port 3306 on the VE2 (db server) with: Code: #/sbin/iptables -A INPUT -i venet0 -s 192.168.1.0/24 -p tcp --destination-port 3306 -j ACCEPT Still I get to the same error. :-( In the meantime, I did the following in the VE2 db server: Code: #mysql -u root -p #grant all on *.* to [email protected] identified by 'password'; It let me go beyond the selection of db, but I got the the following error in next step: And the last solution mentioned here (http://www.howtoforge.com/forums/showthread.php?t=43701&highlight=mysql+server) does not apply to my case as I am yet to install the ispconfig3 and there is any links as mentioned to the clientdb. And I am just confused whether I have to install everything [including the webservers in the db server (VE102 in my case] in case I try to go after Till's advice: Please suggest. Thanks!!! z
tried this too I tried as stated here, too: http://how2forge.org/forums/showthread.php?t=30009 by installing mysql-client on VE101 (web server) and unsuccesful. I can connect using 'mysql -h 192.168.1.102 -u root -p' where the IP is my db server VE. Then I tried to do as instructed here: http://sudhaker.com/linux-unix/openvz/isolated-mysql-installation-openvz-cluster.html Still, I am getting : Has anyone encountered such a problem?
Works with others, but not ispconfig3 3.0.2 installation In order to check whether this problem is dbserver-side or ispconfig3 installation script, I downloaded icebb to the VE101 (webserver where I want to install ispconfig 3) and installed the db in VE102. The installation went smoothly without any hitches. The following is the output from the VE102 (db server) Code: mysql> show grants for [email protected]; +--------------------------------------------------------------------------------------------------------------------------+ | Grants for [email protected] | +--------------------------------------------------------------------------------------------------------------------------+ | GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.101' IDENTIFIED BY PASSWORD '*E1TB0C38323EC954FM1908F585476Q42037713J6' | | GRANT ALL PRIVILEGES ON `dbispconfig`.* TO 'root'@'192.168.1.101' | | GRANT ALL PRIVILEGES ON `icebb`.* TO 'root'@'192.168.1.101' | +--------------------------------------------------------------------------------------------------------------------------+ 3 rows in set (0.00 sec) If I could install icebb with the same database and permissions, then there could be something with the ispconfig3 installer that prevents me installing ispconfig3 on a remote db host (in my case 192.168.1.102). Likewise, I can access the db server (in VE102) after making necessary changes in the /etc/phpmyadmin/config.inc.php in VE101as of below: Code: $i++; $cfg['Servers'][$i]['host'] = '192.168.1.102'; $cfg['Servers'][$i]['port'] = ''; // MySQL port - leave blank for default port $cfg['Servers'][$i]['socket'] = ''; // Path to the socket - leave blank for default socket $cfg['Servers'][$i]['connect_type'] = 'tcp'; // How to connect to MySQL server ('tcp' or 'socket') $cfg['Servers'][$i]['extension'] = 'mysql'; // The php MySQL extension to use ('mysql' or 'mysqli') $cfg['Servers'][$i]['compress'] = FALSE; // Use compressed protocol for the MySQL connection (requires PHP >= 4.3.0) $cfg['Servers'][$i]['auth_type'] = 'config'; $cfg['Servers'][$i]['user'] = 'root'; $cfg['Servers'][$i]['password'] = 'password'; Thus, it seems like it is the problem with the ISPConfig3 installer. I am struggling to install ISPConfig3 for some 36 hours in such a setup, but in vain. Any inputs will be highly appreciated. I really like and need ISPConfig. Thanks! zenny
[SOLUTION] Mysql in a different host inaccessible Just whining for a day and half and found a solution by executing the following command at mysql prompt on the VE running db-server: Code: #mysql -u root -p <ENTER> mysql> GRANT ALL PRIVILEGES ON * . * TO 'root'@'192.168.1.101' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ; However, once the ispconfig3 gets installed, the ispconfig@localhost user in the db-server should be renamed to [email protected] to get rid of the error that is encountered while login to ISPconfig3 gui. all previous tweaks were reverted back. However, I am trying to figure out how can I configure the mail server in VE103 as I installed without configuring mail while installing ISPConfig3. Any hints will be appreciated. z
