When installing Drupal on Centos 7, having your database installed on a separate server, most likely you have not installed the mysql or mariadb client tools required by drush. The following one liner will correct your problem.
yum install mariadb -y

grep ' 404 ' /var/log/nginx/access.log* | awk '{print $7}' | sort -n | uniq -c | sort -rn > /root/top404.txt
This will find, group, count and sort by count descending for all non compressed log files. Note that the print $7 is the column number delineated by spaces. You may have to experiment with the index number based on log settings.
Navigate to the folder that you want to operate on. Then execute the following line.
find . -depth |while read LONG; do SHORT=$( basename "$LONG" | tr '[:upper:]' '[:lower:]' ); DIR=$( dirname "$LONG" ); if [ "${LONG}" != "${DIR}/${SHORT}" ]; then mv "${LONG}" "${DIR}/${SHORT}" ; fi; done
Most of the cloud service provider disable swap on their systems to better isolate resources at the server level. There is a way around this, you can create your own swap file and configure the system to use the file. This has a bit more overhead than a swap partition so use it wisely.
You can set swappiness while running: sysctl vm.swappiness=10
To retain the settings when rebooting: vi /etc/sysctl.conf and add or edit; vm.swappiness = 10
To query for the current swappiness setting: cat /proc/sys/vm/swappiness
The setting range is 0 to 100. The higher the number the sooner swap is used preserving RAM. A swappiness setting of zero means that the disk will be avoided unless absolutely necessary (you run out of memory), while a swappiness setting of 100 means that programs will be swapped to disk almost instantly.
