How To Install and Secure Memcached on Ubuntu 16/18.04 ?

How to Install Redis on Ubuntu 16/18/20 LTS ?

With the new transactional file locking in place, we felt it was time to get rid of APCu and replace our cache with Redis instead. APCu is kind of old, and from our understanding, it doesn’t work well with the new Laravel locking system. Redis cache is the preferred way to go. Update APT and Install Development Tools First:   # apt update && apt upgrade # sudo apt install build-essential -y # apt-get install autoconf automake gdb git libffi-dev zlib1g-dev libssl-dev Install and Enable Redis Server # sudo apt install redis-server # sudo systemctl enable redis-server Change Redis configuration in file /etc/redis/redis.conf # vi /etc/redis/redis.conf bind 127.0.0.1 ::1 maxmemory 500mb maxmemory-policy volatile-lru port 6379 and after change the system configuration: (for redis use) # echo 1 > /proc/sys/vm/overcommit_memory add at file /etc/sysctl.conf (for redis use) vm.overcommit_memory = 1 [at end of the line] and update the system configuration: # sysctl -p Restart Red

How to remove exim mail server from VestaCP on Ubuntu ?

Of all MTAs we’re reviewing, Postfix has the strongest emphasis on security. The likely reason is that it was created by Wietse Zweitze Venema , a prolific freeware security specialist. Sendmail cannot be considered a secure MTA. Moreover, Postfix was originally designed to mitigate the vulnerabilities associated with Sendmail. Exim is quite secure for most cases but loses to Postfix. A proper configuration of your Postfix MTA provides improved defenses against spam, abuse, and leakage of sensitive data. So i don't want to use EXIM as a MTA with VestaCP on Ubuntu. I want to remove exim  completely from my VestaCP control panel. I want to use Postfix/Dovecot RSPAMD as a AntiSPAM solutions . I will publish details in next tutorials  Check Exim Status # systemctl status exim # systemctl status exim4 Remove Frozen mail # exim -bp # exim -bpc # exim -bp | awk '/^ *[0-9]+[mhd]/{print "exim -Mrm " $3}' | bash Remove Completely  # sudo apt remove --auto-remove exim4 #
