Start created CT, login as root and excute following commands to install needed programs and OxOOL Community edition:
```Shell
yum install vim openssh* net-tools unzip wget -y
cd /etc/yum.repos.d
wget http://www.oxoffice.com.tw/rpm/el/oxool-community-v4-centos7.repo
yum upgrade -y
yum groupinstall "OxOOL Community Group" -y
```
Start OxOOL Community edition service when booting and reboot
```Shell
systemctl enable oxoolwsd
reboot
```
Check if OxOOL Community edition starts normally
```Shell
netstat -tlnp
```
You should get some results like this:
```Shell
tcp6     0    0    :::9980		      :::*   	LISTEN   644/oxool
```
P. S. When steps above are finished, you can use "More"→"Convert to template" to generate new LXC template that contains OxOOL Community edition.
