I have two issues - sql and received mail

Hello, I have minikvm128 - Debian 7 32bit with I-mscp 1.2.9 cpanel and cloudflare
 
1- All my sites down. I face this error more than twice a week [SQL error: No such file or directory ].after I restart mysql sites up and running.

service mysql restart


    [ ok . Stopping MySQL database server: mysqld
    [ ok . Starting MySQL database server: mysqld .
    [info] Checking for tables which need an upgrade, are corrupt or were
    not closed cleanly..

I tried to fix all Database tables via phpmyadmin. all Database fixed and all goes good for day or so. how I can fix this error definitively?

2- I'm able to send mail from my domain [email protected] but not able to receive mail. my cloudflare DNS Records are

AAAA  example.com    points to 6:5:6:5::a1    Automatic   
   
AAAA  mail                    points to 6:5:6:5::a1    Automatic   
   
AAAA  webmail            points to 6:5:6:5::a1    Automatic   
   
AAAA  www                 points to 6:5:6:5::a1    Automatic   
   
MX     example.com    mail handled by mail.example.com  Automatic  [ Server  mail.example.com  - Priority 5 ]

same value via  I-mscp 1.2.9 cpanel

Thank you in advance.

Re: I have two issues - sql and received mail

perhaps you are running out of ram, what do your logs say?

Re: I have two issues - sql and received mail

Totally depends how far in to your term you are, you will see upgrade/downgrade options in the client area.

It wont be more than the difference between the 2 packages on the website http://littlehappycloud.net/

Re: I have two issues - sql and received mail

Upgrade is done, when your server comes up it will have more ram, while your at it you might want to post your /etc/my.cnf file if you want some tips on keeping mysql in check.

If you want to take advantage of the extra 3GB disk space you will need to mount the rescue/gparted ISO and resize your partition.

Re: I have two issues - sql and received mail

do you have anything setup in /etc/mysql/conf.d/ ?

Other than that I would suggest the following:

key_buffer              = 512K
max_allowed_packet      = 512K
thread_stack            = 128K
thread_cache_size       = 8
max_connections         = 30
myisam-recover         = BACKUP

query_cache_limit       = 3M
query_cache_size        = 3M

expire_logs_days        = 5
max_binlog_size         = 5M

[mysqldump]
quick
quote-names
max_allowed_packet      = 6M

[mysql]

[isamchk]
key_buffer              = 1M

Also disable innodb, that will bring your mysql footprint down to around 20mb during standard use, standard use being this forum for example, gets around 30k p/month impressions, however its been well tuned and the software has been selected for being light weight, so it runs on 64mb, used to be the whole thing on 64mb now I have a pure mysql 64mb box and a web server on 64mb to keep it fast (on the same pysical node)

If your trying to run multiple wordpress sites or other heavy CMS though with plugins etc and no backend optimization then your just going to need more ram.

Re: I have two issues - sql and received mail

InnoDB is eating up memory is due to the buffer_pool_size default to 128MB

If you like to have InnoDB running, you can tune InnoDB to use lesser amount of ram:

[mysqld]
innodb_buffer_pool_size=5M
innodb_log_buffer_size=256K
#max_connections=10
key_buffer_size=8
innodb_additional_mem_pool_size=512K

Ref: http://dev.mysql.com/doc/refman/5.5/en/ … _pool_size

Re: I have two issues - sql and received mail

@ Anthony
I have multiple wordpress sites all gets around 1k v/month and site needs innodb to run gets around 3k v/month.

@ guyz92 If
I change InnoDB setting can slowdown my site or other ?


Is changing mysql to mariaDB  and/or Increase swap size can help. BTW what is best value for swap size?

Re: I have two issues - sql and received mail

swap is not a replacement for ram, relying on it will slow down your sites for sure, the issue with your mysql settings, it will use as much ram as it can even to the point of killing itself because your essentially instructing it to pour 2 pints in to a 1 pint glass.

Changing your innodb buffers wont slow down your sites, unless they simply need more ram to operate (unlikely with that volume), again this is a pure ram issue, your literally instructing mysql to use more ram than you have, change them as guyz92 suggested, monitor your server during peak times if it still has plenty of free ram then increase your buffers a bit.

It shouldn't be slowing down that much.

That is just a RAMDISK that InnoDB use.

Since you are using Wordpress, you should enable WP Super Cache to generate static HTML to decrease the load and speed up the blog.

Re: I have two issues - sql and received mail

2nd issue

I'm able to send mail from my domain [email protected] but not able to receive mail.

My cloudflare DNS Records are

AAAA  example.com    points to 6:5:6:5::a1    Automatic   
   
AAAA  mail                    points to 6:5:6:5::a1    Automatic   
   
AAAA  webmail            points to 6:5:6:5::a1    Automatic   
   
AAAA  www                 points to 6:5:6:5::a1    Automatic   
   
MX     example.com    mail handled by mail.example.com  Automatic  [ Server  mail.example.com  - Priority 5 ]

Same value via  I-mscp 1.2.9 cpanel.

What's correct DNS Records on both I-mscp 1.2.9 cpanel and cloudflare?

Re: I have two issues - sql and received mail

can you telnet in to port 25 on your IPv6 address?

have you confirmed your mail server is listening on port 25 over ipv6 with netstat?

Re: I have two issues - sql and received mail

Lets say :

Server A (IPv4: 222.111.222.111, IPv6: None) trying to send email to your IPv6 SMTP Server, it will not be able to send at all.
You should check and see if that email is on hold on the SMTP Server.
