# lxc_manager_node
|
|
This has been tested on **clean** install of ubuntu 14.04 64bit.
|
|
|
|
## install
|
|
Update you system to the newest packages and reboot. You may need to do this several times:
|
|
```bash
|
|
sudo apt-get update && sudo apt-get upgrade && sudo reboot
|
|
```
|
|
|
|
Once there are no more updates, add the `virt` user:
|
|
```bash
|
|
sudo adduser virt
|
|
```
|
|
Make the password something strong, and remember it.
|
|
|
|
Now you can install the packages we need:
|
|
```bash
|
|
sudo apt-get install git nodejs npm lxc redis-server
|
|
```
|
|
|
|
remap `nodejs` to `node`:
|
|
```bash
|
|
sudo ln -s /usr/bin/nodejs /usr/bin/node
|
|
```
|
|
|
|
And install the node packages:
|
|
```bash
|
|
sudo npm install -g forever
|
|
```
|
|
give the `virt` user network access:
|
|
```bash
|
|
echo "virt veth lxcbr0 1024" | sudo tee -a /etc/lxc/lxc-usernet
|
|
```
|
|
|
|
lets set up the config file for the `virt` user, first switch users:
|
|
```bash
|
|
su virt
|
|
```
|
|
|
|
The lines below will add the proper config file:
|
|
```bash
|
|
mkdir -p ~/.config/lxc
|
|
echo "lxc.id_map = u 0 `grep -oP '^virt:\K\d+' /etc/subuid` `grep -oP '^virt:\d+:\K\d+' /etc/subuid`" > ~/.config/lxc/default.conf
|
|
echo "lxc.id_map = g 0 `grep -oP '^virt:\K\d+' /etc/subgid` `grep -oP '^virt:\d+:\K\d+' /etc/subgid`" >> ~/.config/lxc/default.conf
|
|
echo "lxc.network.type = veth" >> ~/.config/lxc/default.conf
|
|
echo "lxc.network.link = lxcbr0" >> ~/.config/lxc/default.conf
|
|
```
|
|
Its safer at this point to reboot the system, `exit` back to the privlaged user and `reboot`
|
|
|
|
**SSH or log dercily into the `virt` user!!!** this will not if you use su!
|
|
|
|
Now you can can create a test container:
|
|
```bash
|
|
lxc-create -t download -n test-ubuntu -- -d ubuntu -r trusty -a amd64
|
|
```
|
|
start and attach the container to make sure everthing is ok:
|
|
```bash
|
|
lxc-start -n test-ubuntu -d
|
|
lxc-attach -n test-ubuntu
|
|
```
|
|
If everything worked you can stop and delete the container
|
|
```bash
|
|
lxc-stop -n test-ubuntu
|
|
lxc-destroy -n test-ubuntu
|
|
```
|
|
|
|
|
|
```bash
|
|
sudo add-apt-repository ppa:ubuntu-lxc/daily
|
|
sudo add-apt-repository ppa:ubuntu-lxc/cgmanager-stable
|
|
```
|
|
# auto start
|
|
## crontab
|
|
```bash
|
|
@reboot forever start -c '/usr/bin/nodemon -e js,ejs' -a -o /home/virt/manager/proxy.out.log -e /home/virt/manager/proxy.err.log /home/virt/manager/bin/www
|
|
@reboot /usr/bin/forever start -o /home/virt/manager/proxy.out.log -e /home/virt/manager/proxy.err.log /home/virt/manager/app.js
|
|
```
|
|
|
|
##rc.local
|
|
```bash
|
|
sudo cgm create all virt
|
|
sudo cgm chown all virt $(id -u virt) $(id -g virt)
|
|
```
