LXC (LinuX Containers) is an operating system\u2013level virtualization method for running multiple isolated Linux systems (containers) on a single control host. In this blog, we will explain, how to host a WordPress site in LXC & migrate it to another server<\/p>\n
Installing LXC<\/p>\n
To downloads the package lists from the repositories and “updates” them to get information on the newest versions of packages and their dependencies,<\/p>\n
[js]
\napt-get update
\n[\/js]<\/p>\n
To install LXC ,<\/p>\n
[js]
\napt-get install lxc -y
\n[\/js]<\/p>\n
To create a container name application,<\/p>\n
[js]
\nlxc-create -n application -t ubuntu
\n[\/js]<\/p>\n
-n : Name of Container
\n-t : LXC template. In our case, we’re using ubuntu template<\/p>\n
It will take a while to create a container, once it has been created, it will give you username and password to login into your container.<\/p>\n
To list running status of containers,<\/p>\n
[js]
\nlxc-ls \u2013fancy
\n[\/js]<\/p>\n
[js]<\/p>\n
root@ip-172-31-34-48:~# lxc-ls –fancy
\nNAME STATE IPV4 IPV6 AUTOSTART
\n——————————————-
\napplication STOPPED – – NO
\nroot@ip-172-31-34-48:~# <\/p>\n
[\/js]<\/p>\n
To start a container,<\/p>\n
[js]
\nlxc-start -n application -d
\n[\/js]<\/p>\n
It will give you a login prompt, login with the user credentials that you’ve got above.<\/p>\n
Installing WordPress Site<\/p>\n
Install all the necessary packages,<\/p>\n
[js]
\napt-get install mysql-server php5-mysql nginx php5-fpm php5-gd libssh2-php -y
\n[\/js]<\/p>\n
Create a Database,<\/p>\n
[js]
\nmysql -u root -p
\nCREATE DATABASE wordpress;
\nCREATE USER user@localhost IDENTIFIED BY ‘user123’;
\nGRANT ALL PRIVILEGES ON wordpress.* TO user@localhost;
\n[\/js]<\/p>\n
Download and untar wordpress<\/p>\n
[js]
\ncd \/tmp\/
\nwget http:\/\/wordpress.org\/latest.tar.gz
\ntar xzvf latest.tar.gz
\n[\/js]<\/p>\n
Configure wordpress<\/p>\n
[js]
\ncd \/tmp\/wordpress
\nmv wp-config-sample.php wp-config.php
\n[\/js]<\/p>\n
Make below changes in wp-config.php<\/p>\n
[js]<\/p>\n
\/\/ ** MySQL settings – You can get this info from your web host ** \/\/
\n\/** The name of the database for WordPress *\/
\ndefine(‘DB_NAME’, ‘wordpress’);<\/p>\n
\/** MySQL database username *\/
\ndefine(‘DB_USER’, ‘user’);<\/p>\n
\/** MySQL database password *\/
\ndefine(‘DB_PASSWORD’, ‘user123’);<\/p>\n
[\/js]<\/p>\n
copy files to document root<\/p>\n
[js]
\nsudo rsync -avP \/tmp\/wordpress\/ \/usr\/share\/nginx\/html
\n[\/js]<\/p>\n
Add an iptables rule to the prerouting table of host machine, to forward packets on port 80 to our nginx container’s port 80.<\/p>\n
[js]
\niptables -t nat -A PREROUTING -i eth0 -p tcp –dport 80 -j DNAT –to 10.0.3.245:80
\n[\/js]<\/p>\n
Now you can access your site, by
\nhttp:\/\/your-public-ipaddress ( host machine )<\/p>\n
Migrating Your lxc container to another host<\/p>\n
Install LXC on destination host and stop LXC on your source host<\/p>\n
[js]
\nrsync -va \/var\/lib\/lxc\/container-name destination-host-ip:\/var\/lib\/lxc\/
\n[\/js]<\/p>\n
start container on your destination host.<\/p>\n
Once you’re done with your containers, you can stop it<\/p>\n
[js]
\nlxc-stop -n application
\n[\/js]<\/p>\n
or if you want to terminate your container, you can destroy it<\/p>\n
[js]
\nlxc-destroy -n application
\n[\/js]<\/p>\n
