InnoDB is insanely picky about it's config; if something's not right, it'll just give up and go home. To make a change to the log file size without data loss:
Adds a DrupalAdminToolbar cookie that is needed server-side to prevent "slow load JS flicker"
Most users won't have access to the admin toolbar, so this is probably a moot point
See this exchange with module's maintainer, yhahn, on #open-atrium:
First create respective subdomains like ns1.mydomain.com and ns2.mydomain.com:
To close port #3306 from outside networks add this to /etc/my.cnf' under the [mysqld] section:
then run 'service mysqld restart' and then 'netstat -tln' to see if the port comes up in the list of open ports:
root@my:/var/named# netstat -tln Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN
Some server that I am working with has no swap space mounted in the server. Swap is necessary as backup of our physical memory in case system needs more memory than what it has at that time and also increase application loading speed especially when starting and closing application.
Swap space can be setup in 2 ways, as partition or as a file. Since this server is already online and I have many free partition left in “/” partition, so it may good for me just to create swap file rather than swap partition.
My variables as below:
OS: RHEL 5.7 64bit (Tikanga)
First, install the stock Centos kernel via yum. Write down the version it installs!
yum install kernel
Check in /boot if the files are there:
ls -al /boot
You should see "vmlinuz-2.6.32-279.19.1.el6.x86_64" and "initramfs-2.6.32-279.19.1.el6.x86_64.img"
Then, check your root partition, and write it down. Look for "/", and write down the filesystem (/dev/md1 in this example)
df Filesystem 1K-blocks Used Available Use% Mounted on rootfs 20317384 997168 18296272 6% /
1. Type "parted /dev/", usually "parted /dev/sda".
2. Once inside parted type "mktable":
-> Table type: msdos
-> Destroy data: yes
3. GPT should now be removed.
The /proc/sys/dev/raid/speed_limit_min is config file that reflects the current "goal" rebuild speed for times when non-rebuild activity is current on an array. The speed is in Kibibytes per second, and is a per-device rate, not a per-array rate . The default is 1000.
The /proc/sys/dev/raid/speed_limit_max is config file that reflects the current "goal" rebuild speed for times when no non-rebuild activity is current on an array. The default is 100,000.
To see current limits, enter:
# sysctl dev.raid.speed_limit_min # sysctl dev.raid.speed_limit_max
If you’ve just installed CentOS 6 on software RAID and it won’t boot off /dev/md0, try the following:
1. Using your CentOS install media, boot in to rescue mode
2. Once you are booted in to rescue mode, select the “start shell” option
3. Enter the following command:
1. Install Rkhunter
yum install -y rkhunter file
2. Update Rkhunter
3. Run a Test Scan (help to prevent false positives):
4. Setup a daily scan report:
vi /etc/cron.daily/rkhunter -----------------//-------------- #!/bin/bash ( /usr/bin/rkhunter --versioncheck --nocolors /usr/bin/rkhunter --update --nocolors /usr/bin/rkhunter --checkall --nocolors --skip-keypress ) | /bin/mail -s 'rkhunter Daily Run ' email@example.com exit 0 -----------------//--------------
