I am trying to get mysql to start at boot without any success.
The mysqld scripts works fine when run from the command line, but it does not work when i use the links created by chkconfig. I checked the boot.log and found that mysql starts but then it stops or gets shutdown. This is the log message:
Starting mysqld daemon with databases from /data/mysql [ OK ]
Starting cups: [ OK ]
STOPPING server from pid file /var/run/mysqld/mysqld.pid
starting DenyHosts: /usr/bin/denyhosts.py --daemon --config=/usr/share/denyho
sts/denyhosts.cfg
090727 04:35:47 mysqld ended
The same init script works fine in Ubuntu.
I am not able to start mysql server...when i type command sevice mysqld start it saysMySQL Daemon failed to start.Starting mysqld: [FAILED]so how to solve this problem ?

I just installed a brand new ubuntu server 10.04 32-bit, choosing the LAMP option on install. Upon reboot I couldn't connect to mysql from another machine, so on this new server I changed the file at /var/mysql/my.cnf
[Code]...
Ubuntu server 10.04 comes with a new event based startup system, and I wonder if that can be responsible for this problem. The server has been upgraded from 9.10. On reboot mysql does not always manage to start... /var/log/mysql/error.log has info similar to this:
100511 19:05:00 [ERROR] Can't start server: Bind on TCP/IP port: Cannot assign requested address
100511 19:05:00 [ERROR] Do you already have another mysqld server running on port: 3306 ?
100511 19:05:00 [ERROR] Aborting
So apparently port 3306 is not 100% unused when mysql tries to open it or somehow network connections are not ready, even if mysql start is supposed to wait for 'net-device-up' and 'local-filesystems' according to /etc/init/mysql.conf. This does not happen on all reboots. I am supposed to be able to start it manually with command 'start mysql' but that does not seem to work also. When I try start it again, it says mysql is running but no databases can be reached and mysqld is not active, reboot and good luck is all that helps...
As far as I know there are no firewalls installed, at least none I have manually configured and it has worked with no problems on 9.10. So this new upstart thing seems responsible. It simply does not let mysql wait until it can start in good way. That also explains why it's a random problem. If all starts happen when and if there is free processor time, it does not always start things in the same order on every reboot. The key here is port 3306, or whatever port mysql is configured to use. The upstart system simply needs delay the start until the port is 100% free and available for the system to use.
Recently, few days or maybe a week ago I updated mysql and now mysql service do not start at boot. I must start it manualy, before this update it start automaticly.

I just compiled mysql apache and php from source and I have apache to start up from boot but I don't exactly know how to get mysql to do the same.
Edit: Also how do I add mysql to path? Should I just symlink it to somewhere thats in the path or what? And if that is the case wheres the best place to symlink it too.

View 9 Replies View RelatedCurrently when the system boots, It boots jabberd2 before mysql. So jabber fails. Then, later mysql is loaded. I either want to force jabber to load mysql first, or make the system boot mysql first. I've tried changing /etc/init.d/jabberd2 to say "# Required-Start:
mysql $network $named $remote_fs"...
However, insserv says that mysql service has to be enabled... so I assume that's an issue because mysql is an upstart script.
mysqld not running on boot, I can start it manually with
Code:
sudo -u mysql mysqld
If I attempt to start it with Upstart I get

How to make sure mysql process comes up automatically after every reboot
Since /etc/rc2.d/S19mysql does not exists anymore, and then init.d/mysql uses /sbin/start, I am unable to use mysql server anymore: me@mycomputer~#start mysql [ret] ...... for hours this command never returns so that ^C aborts...
me@mycomputer~#ps axw |grep mysql ( no results, no mysql!!! ) me@mycomputer~#stop mysql [ret] no returns either!!! This upstart [start|stop] thing seems a total failure for mysql!!!

I thought that the problem is in the phpMyAdmin not in the mysql. But now i think different. It seems that the problem is right in the mysql. I think that there was no root user, when mysql was freshly installed. Unfortunately i did everything i can find on internet (some tutorials) but they don`t helped me at all, maybe i fu**ed up the mysql service. So i reinstalled it, and when i want to start it there is no file mysql.sock and i get the following:
linux-nepg:~ # service mysql restart
Restarting service MySQL
Shutting down service MySQL done
Starting service MySQL warning: /var/lib/mysql/mysql.sock didn't appear within 30 seconds
Basically, i have a clustered filesystem using GlusterFS. This is ultimately going to host a very large number of files.
It is mainly used as a storage destination for backups, and historical copies of files.
Remote servers sync using unison every few minutes. A local script will run over the whole filesystem once per hour looking for new files/folders, and files that have been updated based on their timestamp.
99% of filesystem access is browsing the directory structure, listing directory contents and checking the modification times of files. Access to the actual content of a file is minimal. Only a tiny fraction of the filesystem is actually modified from hour to hour.
GlusterFS alone is quite slow when browsing the directory structure. (ie. "ls -Rl /data") The speed of things for actually transferring file content is sufficient for my requirements.
What I need is to vastly improve performance when running operations such as "ls -Rl /data". (/data is the mount point)
I believe the best way to do this is to implement caching. The cache options within GlusterFS are simply not sufficient here.
My first thought was to re-export the GlusterFS mount with NFS, and then mount the NFS share and set the cache on the client to a very long expiry. (like 86400 = 24 hours) It is my understanding that any change made to a file using the mount point will invalidate the cache entry for that file. (it is only mounted in one place, so no changes possible at the back end.)
I did this using the kernel based NFS server, but ran into major problems with the "Stale NFS" errors which from reading is due to a problem related to FUSE that doesnt sound like its going to be fixed soon. Aside from the Stale errors, this did provide a suitable boost in performance.
I tried the beta of GlusterFS that has the integrated NFS server (so presumably, no FUSE) but I could not get this to compile properly on our servers.
Finally, I tried using the Gluster patched version of unfs3 that uses boost to talk to Gluster instead of FUSE. Now this works, but for some reason the NFS client cache doesnt seem to cache anymore.
One last thing that I was looking at is the possibility of running a simple cache layer in front of either GlusterFS or NFS. I believe Cache-FS is the tool for the job but I have been unable to get that to work - I believe it is disabled in my kernel or something. (mount command says cachefs is unknown)
I am running Ubuntu 8.04 on most servers, but have upgraded one to 10.04 to try and get around Kernel limitations. My servers are all 32 bit (I know, not recommended for GlusterFS) and its very difficult for me to change this. (its a live system)
I quite simply need to add a cache for the directory structure information, and then maybe export this with NFS so that it can be mounted on a *single* server. (the cache can be on the server where it is mounted if required, but due to the large size of the cache - it may be better to have a server dedicated for the cache)
I am running GlusterFS 3.0.5 in a replicate/distribute manner.
