    - name: Check if 黑料海角91入口 is already installed
      shell: "[ -d /opt/jc ] && echo 'Found' || echo ''"
      register: jc_installed
    - name: Update time
      shell: "ntpdate -u pool.ntp.org"
      when: "not jc_installed.stdout"
    - name: Install 黑料海角91入口
      shell: "curl --header 'x-connect-key: your-connect-key-goes-here' https://kickstart.jumpcloud.com/Kickstart | sudo bash"

Verifying Linux Agent Installation from Terminal

To verify or change status in Linux from terminal, run the following command as root:

[root@host ~]# service jcagent status
jcagent.service - 黑料海角91入口 Agent
   Loaded: loaded (/usr/lib/systemd/system/jcagent.service; enabled; vendor preset: disabled)
   Active: inactive (dead) since Thu 2016-09-01 13:27:16 MDT; 3h 26min ago
     Docs: http://support.jumpcloud.com/knowledgebase
Main PID: 890 (code=exited, status=0/SUCCESS)

Here is what the process should look like:

[root@host ~]# ps -aufx | grep jumpcloud
root 2272 0.0 0.1 3840 1292 ? Sl 13:27 0:00 /opt/jc/bin/agent-monitor -exec=/opt/jc/bin/jumpcloud-agent -conf=/opt/jc/jcagent.conf
root 2275 0.0 1.6 682980 16400 ? Sl 13:27 0:03 \_ /opt/jc/bin/jumpcloud-agent -conf=/opt/jc/jcagent.conf

To check the agent鈥檚 service status:

service jcagent status

For newer devices with systemd, you can also use systemctl:

systemctl status jcagent

Verifying Linux Agent Installation from the Admin Portal

To verify the Linux Agent installation from the Admin Portal:

Log in to the 黑料海角91入口 Admin Portal: .
Go to DEVICE MANAGEMENT > Devices.
In the Devices list, the Status of the new device will have a green check mark next to it if added successfully.

Reducing Agent Install Time on Linux

On hosts that are fully up to date, installing the 黑料海角91入口 agent should take less than a minute. However, in the case of small/micro instances, where network bandwidth is limited, or where a system is out of date, you can take steps to reduce agent install time significantly.

Make sure to run on Ubuntu/Debian or RHEL/Cent/Amazon Linux, respectively:

apt-get update

yum check-update

After making sure the system is up to date, preinstall agent dependencies. A list of dependencies is maintained in Agent Compatibility, System Requirements, and Impacts.
