Linux Tricks

Linux stuff I often have to lookup. Just my personal list of things.

shutdown -rF now
xauth add `hostname`/unix:0 . `openssl rand -hex 32`
  • yum versionlock - allows to lock an rpm
  • install faster random for dns etc.
yum install haveged;
systemctl enable haveged;
systemctl start haveged
sudo visudo -f /mnt/etc/sudoers
netstat -tulpn
xargs yum -y install < file
  • Create Default Home Directory
mkhomedir_helper username
use tmpfiles.d and have your package create at startup or boot a file or directory /usr/lib/tmpfiles.d/mydaemon.conf :
man tmpfiles.d

#Type Path            Mode UID      GID    Age Argument
d     /run/mydaemon   0755 myuser myuser   -   -
rpm -Uvh --nodeps $(repoquery --location <module>)
  sudo journalctl --vacuum-time=3weeks

MySQL

  • UTF8
  • Get a list of processes to kill
 SELECT GROUP_CONCAT(CONCAT('KILL ',id,';') SEPARATOR ' ') 
 'Paste the following query to kill all processes' 
 FROM information_schema.processlist 
 WHERE user<>'system user'
 
  • install latest MariaDB
curl -sS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash
  • Move/Rename a DB to another
mysql -u username -ppassword old_db -sNe 'show tables' | while read table; \ 
   do mysql -u username -ppassword -sNe "rename table old_db.$table to new_db.$table"; done
  • database dump without charset
  mysqldump -u <user> -p --skip-add-locks --skip-set-charset <DB> <tables ...>
  • Disable foreign key checks in a session
SET FOREIGN_KEY_CHECKS=0;

SSL Certificates

Version Control

  git update-index --chmod=+x filename.sh

Oracle

SC Backup

Matricom gBox Q

KVM

QNAP

Zend Framework

Video ffmpeg

Convert wmv to mp4

ffmpeg -i <input> -c:v libx264 -c:a aac -strict -2 -q:a 100 -crf 23 <output>

Zimbra

Working with the following for chain.pem:
