General :: Some Pointers Required For Configuration Of MySQL On RHEL
Feb 8, 2010
I am new to mysql can some one provide me the documentation or some recommended links to start the configuration of mysql server on RHEL. Also if I get the database schema, how can I replicate the same in my machine. Any documentation for this?
I have a linux database server (ver 2.6.18-92.el5xen) which i want to configure for sending mails as and when some errors are written into some log files by an oracle process.when i just try to run this command mailx -s "test.it just does n't show any output and kind of hang.Pls tell me the step by step process for configuring the server so as to send mails from it. Also I am not aware if the required rpm are installed in the machine or not.
I have installed bluez.4.81....but when i install /home/george/Desktop/obexd-0.37.tar.gz,a configuration error occurs telling that libbluetooth is required. Is there any solution??
We are planning to migrate our LINUX server from RHEL 3to RHEL 5. What are the configuration difference between RHEL 3 to RHEL 5 for webserver installations?
I have few doubts regarding fonts configuration in RHEL 5.4.
Code:
[vinay@linuxcoe4 fonts]$ cd /usr/share/X11/fonts [vinay@linuxcoe4 fonts]$ ls 100dpi 75dpi encodings misc TTF Type1 util
[code]....
Also there is no fonts.dir file, which describes fonts under a specific fonts directory in /usr/share/fonts tree. But we can find fonts.dir or fonts.scale file under /usr/share/X11/fonts/ tree. Does files under /usr/share/fonts tree are not dependent on fonts.dir ?
I am trying to install and configure nagios on RHEL 5. I have apache 2 installed and php all working as exepected. When i install nagios following the these steps [URL]. The nagios folder that is suppossed to be placed under apache2's httpd is no where to be seen. So when I try to open localhost/nagios/. It says: The requested URL /nagios/ was not found on this server. What can I do for the nagios to work on this system. The apache and php are working fine.
One monitor is working fine but the display is not coming on other monitor. I guess no problem in monitor because I swapped the cable to check the individual monitor. When I try to install the new driver its giving GCC-VERSION-CHECK while installing. And I do not think I have to install the new driver because it has already one. What should I do to configure the dual monitor. Do I have to edit any configuration file.
My system configuration details are below. Redhat version : Redhat Enterprise Linux WS release 3 (Taroon update 4) Driver in SRBC 26: NVIDIA-LINUX-x86_64-1.0-7664-pkg2.run Nvidia card model : Quadro fx p171 Bios version of Nvidia : 4.35.20.23.07 p/n : 900-50171-0400-0000K 600-50171-0002-201J
I need to tune the mysql and apache server for the comparatively busy webserver. My scenario is like this.
1. The Web request is around 2000 request at a time or more. 2. Each web request will generate one mysql query. 3. The query to database is all read. 4. This server load will be at peak for around 3-4 hours after that the load will subside. As the task will be published, around 300,000 will be viewing the page.
5 quad servers are deployed, load is balanced via DNS but performance is not as expected. Centos 5.5 is used as OS. Top command shows The mysql process is around 185%!
Currently I'm using RHEL 5.3 in my server. Last time I install MySQl Server and it working fine.Then i facing a problem with my server and i reinstall back RHEL. But i didnt use MySql package inside the CD to install MySQL. i install MySQl separately. I download from MySql website. My problem is, i success install MySql in my server. The service also running. But when i type.
I am having no luck configuring ProFTPd on a Debian Lenny production server we use to host our MySQL databases and a few websites. I had originally set it up so I could login and manage our internal sites, but I have the need to allow a few clients in to access their sites that we host. I am trying to root the users in their site directory, which would be "/sites/www.whatever.com/".
It just hit me while typing this. Is it possible to create a user without a shell to prevent login via SSH and set the home folder to /sites/whatever instead of /home/username? That would allow me to continue operating with my current configuration and root them in their site while preventing SSH logins.
i am using liferay5.2(mysql included in the download pack) on fedora. while liferay is working fine but i cannot connect to mysql.i am getting the error
[ [root@localhost ~]# ln -s /var/lib/mysql/mysql.sock /tmp [root@localhost ~]# /etc/init.d/mysqld start Timeout error occurred trying to start MySQL Daemon.
[code]....
i didnt find the mysql.sock file in the location /var/lib/mysql/mysql.sock. i cannot find the portal-ext.properties file also to make intial settings.
I'm trying to list some information of my database. To do that I'm using a class(MyClassDao) that will do all the SQL stuff and returns to me a list of objects with the content of my table (each row = one object). The problem is: my list gets only the first object... on the second index I'm getting 'segfault'.Can someone post something to help me (link, reference or example)?The call for the list function is:
Code: MyClassDao* mcd = new MyClassDao(); MyClass** myClassList;
I am trying to use the sakis3G, i choose the option connect 3G, it asks me about username required by APN?? I have no usernames, and I don't know what APN is? I prefer using the sakis3G since it looks simpler than using USB_ModeSwitch which I didn't manage to understand it from the sites you posted.
I'm using an external USB drive to perform system backups. The script I'm using has a mount command - mount /dev/sdcx /systembak, it works fine until the external drive is mounted into a different USB port which causes the device path to change and the script needs to be modified to reflect that change. Looking in the /dev/disk/ directory I see ./by-id ./by-label ./by-path ./by-uuid. I've been able to mount the disk using one of the device pointers in those directories; are any of those device pointers static or do they change every time the USB disk is plugged into a different USB port.
After having problems with lxde crashing while running Jessie, and re-installing Wheezy, I am not able to mount my WinXP drive. In the past I was able to run pcmanfm and mount the drive from there. It would ask for my root password and then would mount the drive. Now, however, when I click on the drive icon it gives me an error message saying authentication required.
One thing is that when I installed Wheezy I had the WinXP drive disconnected so as to not inadvertently install Wheezy on the wrong drive (I have two identical drives). After installing I connected the WinXP drive and then did a grub update. I can boot either drive, as expected, but I can not mount the WinXP drive from pcmanfm. Do I need to change the Policykit?
I've recently installed a RedHat Enterprise Linux server and am attempting to get PHP/MySQL installed on it. It cannot load the dynamic php mysql module, giving me an error (in /var/log/error_log) that reads as follows:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mysql.so' - /usr/lib/php/modules/mysql.so: undefined symbol: executor_globals in Unknown on line 0
(In fact, it fails to load ALL of the dynamic php modules, either with the "undefined symbol: executor_global" or "undefined symbol: core_globals" I DO NOT WANT to compile anything -- I want to stay with stock RedHat released software.

can not ping from host (RHEL 6) to RHEL 5 in (virtual)? I have stopped iptables on both machines. But still not able to ping from host machine to virtual.
I am trying to download RHEL 5.4 AS version for testing..But under [URL] There is no specific link for AS version or ES version..How can I detect which iso is for AS and which one for ES..? There are separate links for AS and ES version for RHEL 4.x version but why is it not available for RHEL 5.x versions?
Friends i got an opertunity to configure ddns in my office.I already configured staic dns in linux, but this is the first time iam configuring ddns.I just configured ddns in rhel 5.2 in my office.So far every thing working fine,dhcp is giving ip address to the clients and both forward and reverse dns database is updating.
1) In windows we can use flushdns and registerdns commands to update the dns database, like this any command is in linux to update client details in dns database?
2)how to restrict multiple client entries keeping in dhcp database.
3)if i change client hostname it is not updating the dns database,it is keeping the old one.
I have few doubts regarding fonts configuration in RHEL 5.4.
Code: [vinay@linuxcoe4 fonts]$ cd /usr/share/X11/fonts [vinay@linuxcoe4 fonts]$ ls 100dpi 75dpi encodings misc TTF Type1 util [vinay@linuxcoe4 fonts]$ cd /usr/share/fonts/
[Code].....
What is the difference between fonts in /usr/share/X11/fonts and /usr/share/fonts
Also there is no fonts.dir file, which describes fonts under a specific fonts directory in /usr/share/fonts tree.
But we can find fonts.dir or fonts.scale file under /usr/share/X11/fonts/ tree. Does files under /usr/share/fonts tree are not dependent on fonts.dir ?
I believe that SU log messages are supposed to be appended to /var/log/messages but I'm not getting any log entries. I edited the /etc/syslog.conf and added the line below
su.* /var/log/sulog
Then ran /etc/rc.d/init.d/syslog restart (I also ran this prior to editing the syslog.conf file just in case). I'm still not getting any SU log messages.
I have and RHEL5.4 conecceted to an SAN HSV200. When I present a LUN to it, In system-confg-lvm gui appears a device like /dev/mapth/mapth0 (that�s the correct device to multipath) and other like /dev/sda or /dev/dm-N, as uninitialized entities. How could I configure to not display this device (/dev/sda) and prevent human errors?
This is the things I need:
1- I want (if it is posible...) to disappear the part where it says "uninitialized entities"
2- Is It necesary mantain the partitioning done to default (like /dev/mapper/mpath0p1) with device-mapper-multipath (kpartx command)? or Can I delete it without future problems?
