Adding new users and admins to Linux server

Check Installing CentOS 6.2 on VMware post.

Using admin user avoids common mistakes done when logging as root, instead use sudo to run root commands.

mkdir /server
 
#adding web-server user www
adduser www -d /server -s /sbin/nologin
 
#adding admins group to use instead of root
groupadd admins
visudo
#add
%admins ALL=(ALL)       NOPASSWD: ALL
 
#add new admin 
adduser admin -g admins
#set password
passwd admin
 
#add email for user admin
vi /etc/aliases
#add
admin: admin@example.com
#rebuild data
newaliases

ulimit -n unlimited - www
#check default number of concurrently open file descriptors

#set the number to high value depending on server config
echo '1773914' > /proc/sys/fs/file-max

mounting partitions with noatime

Check Installing CentOS 6.2 on VMware and increase linux file descriptors posts.

This should help reduce disk IO by telling the system not to update inode access times. more here

vi /etc/fstab
#add noatime to the options of the / file system ex:
/dev/mapper/vg_centos6-lv_root /                       ext4    defaults,noatime         1 1

- remount file system

mount -o remount /
#check
cat /proc/mounts | grep noatime
