==CentOS==

===Add EPEL repository===

http://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/

 ## RHEL/CentOS 7 64-Bit ##
 wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
 rpm -ivh epel-release-7-5.noarch.rpm


===Install LXC===
 yum install lxc lxc-templates

===Other install===
 yum install bridge-utils 

 yum install -y libvirt
 systemctl start libvirtd
 brctl show
bridge name bridge id       STP enabled interfaces
virbr0      8000.fea2866efadb   yes     veth7ATCJK



===Config Autostart===

 vi /var/lib/lxc/centos1/config

The startup related values that are available are:
 lxc.start.auto = 0 (disabled) or 1 (enabled)
 lxc.start.delay = 0 (delay in second to wait after starting the container)
 lxc.start.order = 0 (priority of the container, higher value means starts earlier)
 lxc.group = group1,group2,group3,… (groups the container is a member of)


When running the following command this container will autostart
 lxc-autostart

Enable the service to autostart on boot
 systemctl enable lxc.service

====Prevent excess journald activity====
By default, lxc symlinks /dev/kmsg to /dev/console, this leads to journald running at 100% CPU usage all the time. To prevent the symlink, use:

 vi /var/lib/lxc/centos1/config

 lxc.kmsg = 0

===Image creation===
 lxc-create -n centos1 -t centos
 lxc-start -n centos1
Login to Container: The root password is set in the lxc template.


===Normal operations===

====Start====
 lxc-start -n centos1

====Attach====
 lxc-attach -n centos1

====Stop====
To stop:
 lxc-stop -n centos1 

To kill:
 lxc-stop -n centos1 -k

===LAMP installation===

 yum install httpd
 systemctl enable httpd

only before Centos7:
 sudo yum install mysql-server
 sudo service mysqld start
 sudo /usr/bin/mysql_secure_installation

On Centos7 install MariaDB: https://downloads.mariadb.org/mariadb/repositories/#mirror=host-europe&distro=CentOS&distro_release=centos7-amd64--centos7&version=10.1

Here is your custom MariaDB YUM repository entry for CentOS. Copy and paste it into a file under /etc/yum.repos.d/ (we suggest naming the file MariaDB.repo or something similar).
 # MariaDB 10.1 CentOS repository list - created 2016-02-29 20:27 UTC
 # http://mariadb.org/mariadb/repositories/
 [mariadb]
 name = MariaDB
 baseurl = http://yum.mariadb.org/10.1/centos7-amd64
 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
 gpgcheck=1
After the file is in place, install MariaDB with:
 sudo yum install MariaDB-server MariaDB-client



 sudo yum install php php-mysql
 yum search php-
 yum info  name of the module
 yum install php-fpm

 sudo chkconfig httpd on
 sudo chkconfig mysqld on

====Fix for Apache====
https://www.marc.info/?l=lxc-users&m=142483647735314&w=2
I have trouble updating httpd in my containers.

Look for /usr/share/lxc/config/fedora.common.conf (or whatever it is on
fedora, try "rpm -ql lxc"), then comment out this line

 vi /usr/share/lxc/config/centos.common.conf
 lxc.cap.drop = setfcap
