Configuring Cloud-Init
Scenarios
You need to configure Cloud-Init after it is installed.
Prerequisites
- Cloud-Init has been installed.
- An EIP has been bound to the ECS.
- You have logged in to the ECS.
- The ECS uses DHCP to obtain IP addresses.
Procedure
The following operations are required:
- Configure Cloud-Init.
For details, see Configure Cloud-Init.
- Check whether Cloud-Init is successfully configured.
For details, see Check the Cloud-Init Configuration.
Configure Cloud-Init
- Configure the user permissions for logging in to the ECS. If you select user root, enable the SSH permissions of user root and enable remote login to the ECS using a password.
- If you inject a password, use it to log in to the ECS remotely using SSH or noVNC.
- If you inject a key, use it to log in to the ECS remotely using SSH.
- Enable remote login using the password of user root and enable the SSH permissions of user root.
Take CentOS 6.7 as an example. If the value of disable_root in the /etc/cloud/cloud.cfg file is 0, the permissions are enabled. (In some OSs, value true indicates that the permissions are disabled, and false indicates that the permissions are enabled). Set ssh_pwauth to 1, and lock_passwd to False (indicating that user passwords are not locked).
users: - name: root lock_passwd: False disable_root: 0 ssh_pwauth: 1
- Prevent Cloud-Init from taking over the network in /etc/cloud/cloud.cfg.
If the Cloud-Init version is 0.7.9 or later, add the following content to /etc/cloud/cloud.cfg:
Figure 1 Preventing Cloud-Init from taking over the networkNOTE:
The added content must be in the YAML format.
- Enable the agent to access the IaaS OpenStack data source.
Add the following information to the last line of /etc/cloud/cloud.cfg:
datasource_list: [ OpenStack ] datasource: OpenStack: metadata_urls: ['http://169.254.169.254'] max_wait: 120 timeout: 5 apply_network_config: false
NOTE:
- You can decide whether to set max_wait and timeout. The values of max_wait and timeout in the preceding command output are only for reference.
- If the OS version is earlier than Debian 8 or CentOS 5, you cannot enable the agent to access the IaaS OpenStack data source.
- The default zeroconf route must be disabled for CentOS and EulerOS ECSs for accurate access to the IaaS OpenStack data source.
- apply_network_config: false is only requited by users who use Cloud-Init 18.3 or later.
- Add the following content to /etc/cloud/cloud.cfg:
manage_etc_hosts: localhost
This prevents the system from staying in the Waiting for cloudResetPwdAgent state for a long time during ECS startup.
Figure 2 Adding manage_etc_hosts: localhost - Run the vi /etc/ssh/sshd_config command to open the /etc/ssh/sshd_config file using the vi editor.
Change the value of PasswordAuthentication in the sshd_config file to yes.
NOTE:
For SUSE and openSUSE, change the values of the following parameters in the sshd_config file to yes:
- PasswordAuthentication
- ChallengeResponseAuthentication
- Modify cloud_init_modules in the cloud.cfg configuration file.
- Move ssh from the bottom to the top to speed up the SSH login.
- Enable the hostname update. Do not comment out or delete the -update_hostname statement.
cloud_init_modules: - ssh - migrator - bootcmd - write-files - growpart - resizefs - set_hostname - update_hostname - update_etc_hosts - rsyslog - users-groups
- Modify the configuration so that the hostname of the ECS created from the image does not contain the .novalocal suffix and can contain a dot (.).
- Run the following command to modify the __init__.py file:
vi /usr/lib/python*.*/site-packages/cloudinit/sources/__init__.py
The Python version varies depending on the OS.
Press i to enter editing mode. Modify the file content as follows based on the keyword toks:
if toks: toks = str(toks).split('.') else: #toks = ["ip-%s" % lhost.replace(".", "-")] # Comment out this line. toks = lhost.split(".novalocal") # Add this line. if len(toks) > 1: hostname = toks[0] #domain = '.'.join(toks[1:]) # Comment out this line. else: hostname = toks[0] if fqdn and domain != defdomain: #return hostname # Comment out this line. return "%s.%s" % (hostname, domain) # Add this line. else: return hostname
After the modification is complete, press Esc to exit the editing mode and enter :wq! to save the settings and exit.
- Run the following command to switch to the cloudinit/sources folder:
cd /usr/lib/python*.*/site-packages/cloudinit/sources/
The Python version varies depending on the OS.
- Run the following commands to delete the __init__.pyc file and the optimized __init__.pyo file:
rm -rf __init__.pyc
rm -rf __init__.pyo
- Run the following commands to clear the logs:
rm -rf /var/log/cloud-init*
- Run the following command to modify the __init__.py file:
- Run the following command to edit the /etc/cloud/cloud.cfg.d/05_logging.cfg file to use cloudLogHandler to process logs:
vim /etc/cloud/cloud.cfg.d/05_logging.cfg
[logger_cloudinit] level=DEBUG qualname=cloudinit handlers=cloudLogHandler propagate=1
- Delete user linux and the /home/linux directory from the image template.
userdel linux
rm -fr /home/linux
- Ensure that Cloud-Init is enabled.
Delete the /etc/cloud/cloud-init.disabled file by running cloud-init clean --machine-id. If there is no such a file, skip this step.
Check the Cloud-Init Configuration
Run the following command to check whether Cloud-Init has been properly configured:
cloud-init init --local
(Optional) Run the following command to set the password validity period to the maximum:
chage -M 99999 $user_name
user_name is a system user, such as user root.
You are advised to set the password validity period to 99999.
