This topic describes how to install, update, and uninstall Logtail on a Linux server.

Prerequisites

  • At least one Linux server is available.
  • The type of the network that is required to collect logs is determined. You can determine the network type based on the type of the server on which you want to install Logtail and the region where the server resides. For more information, see Select a network type.

Supported operating systems

You can install Logtail on servers that run one of the following x86-64 Linux operating systems:
  • Alibaba Cloud Linux 2
  • Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, and Red Hat Enterprise Linux 8
  • CentOS Linux 6, CentOS Linux 7, and CentOS Linux 8
  • Debian GNU/Linux 8, Debian GNU/Linux 9, and Debian GNU/Linux 10
  • Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04, and Ubuntu 20.04
  • SUSE Linux Enterprise Server 11, SUSE Linux Enterprise Server 12, and SUSE Linux Enterprise Server 15
  • openSUSE Leap 15.1, openSUSE Leap 15.2, and openSUSE Leap 42.3
  • Linux operating systems based on GNU C Library version 2.5 or later

Usage notes

  • If your Logtail version is V0.0, such as Logtail V0.16.x, you can run the installation command in this topic to install Logtail on a Linux server. If you want to install Logtail V1.0 or update the Logtail version to Logtail V1.0, you must add the version number to the installation or update command. For example, if you want to install Logtail V1.0, you must run the ./logtail.sh install cn-hangzhou -v v1 command. If you want to update the Logtail version to Logtail V1.0, you must run the sudo ./logtail.sh upgrade -v v1 command.
  • If you run the installation command on a server on which Logtail is installed, the installer uninstalls Logtail from the server, deletes the /usr/local/ilogtail directory, and then reinstalls Logtail. If the installation is successful, Logtail automatically runs and is added as a startup program.
  • If the installation fails, submit a ticket.
  • If you install Logtail on an Elastic Compute Service (ECS) instance that resides in the classic network and then change the network type from classic network to Virtual Private Cloud (VPC), you must update the Logtail configuration. For more information, see Do I need to update Logtail settings after the network type is changed?

Installation methods

The installation command varies based on the network type of the server on which you want to install Logtail.
Before you run the installation command, you must replace the ${your_region_name} variable in the command with the value for the region where your project resides. The following table describes the value of the ${your_region_name} variable for each region.

Alibaba Cloud internal network (classic network or VPC)

  • If you cannot identify the region where your ECS instance resides, you can use the auto parameter in the Logtail installation script to install Logtail.
    After you configure the auto parameter in the installation command, the Logtail installation script obtains and uses the metadata of the ECS instance to identify the region where your ECS instance resides. For more information about the metadata of ECS instances, see Overview of ECS instance metadata.
    1. Download the Logtail installation script over the Internet.

      The download consumes approximately 10 KB of Internet traffic. 

      wget http://logtail-release-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/linux64/logtail.sh -O logtail.sh;chmod 755 logtail.sh
    2. Install Logtail by using the auto parameter.

      The Logtail installation package for the region is automatically downloaded. The download does not consume Internet traffic. 

      ./logtail.sh install auto
  • If you can identify the region where your ECS instance resides, you can specify the region in the installation command.
    The Logtail installation script is downloaded over an internal network, and Logtail is manually installed. The download does not consume Internet traffic.
    1. Obtain the value of the ${your_region_name} variable for the region where your Log Service project resides.

      For more information about the value of the ${your_region_name} variable for each region, see Table 1. For example, the value of the ${your_region_name} variable for the China (Hangzhou) region is cn-hangzhou.

    2. Replace the ${your_region_name} variable in the command with the value for the region where your project resides, and then run the installation command. 
      wget http://logtail-release-${your_region_name}.oss-${your_region_name}-internal.aliyuncs.com/linux64/logtail.sh -O logtail.sh; chmod 755 logtail.sh; ./logtail.sh install ${your_region_name}
