# Tips and tricks RHCE:

While preforming the RHCE exam reboot your system after configuring each service to check that everything is persistent.
After reboot, check that selinux, firewall-cmd, and service is running ( may not be so obvious with ntp/cron/etc ) 

# Using /root/pre-made-kickstart.ks, serve this file from /ks/ using httpd or nfs to allow remote kickstarting.
kickstart server
	$ yum install httpd
	$ systemctl enable httpd
	$ firewall-cmd --permanent --add-port=80/tcp
	$ firewall-cmd --reload
	$ mkdir /var/www/kickstart
	$ cp /root/anaconda-ks.cfg /var/www/kickstart/
	$ chcon --type httpd_sys_content_t /var/www/kickstart/*
	$ semanage fcontext -a -t httpd_sys_content_t "/custom(/.*)?"
	$ chown -R apache:apache /var/www/kickstart
	$ cp /etc/httpd/conf.d/welcome.conf /etc/httpd/conf.d/kickstart.conf
	$ # Alias /kickstart /var/www/kickstart
	$ # <Directory /var/lib/kickstart>
	$ # DirectoryIndex disabled
	$ systemctl start httpd
	$ grub add: ks=http://192.168.122.57/kickstart/anaconda-ks.cfg append ip=192.168.122.58 netmask=255.255.255.0

nfs server
	$ yum -y install nfs-utils
	$ vi /etc/idmapd.conf
	## line 5: uncomment and change to your domain name
	## Domain = srv.world
	$ man exports | grep 192
	$ vi /etc/exports
	# /home 192.168.122.0/24(rw)
	$ systemctl enable rpcbind nfs-server 
	$ systemctl start rpcbind nfs-server 
	$ firewall-cmd --add-service=nfs --permanent 
	$4 firewall-cmd --reload 

samba server
	$ # Setup a samba server to serve directory /myshare to a user called micky with password 12345678. The workgroup should be called myshare. 
	$ # micky should have read access to /myshare/* and write access to /myshare/write/*
	$ yum install -y samba samba-client samba-common
	$ mkdir /myshare
	$ touch /myshare/test
	$ semanage fcontext -a -t samba_share_t "/myshare(/.*)?"
