max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

To increase the `vm.max_map_count` value to at least `262144`, you can follow these steps:

1. Open a terminal and log in as the root user or use sudo for the following commands.
2. Edit the sysctl.conf file using a text editor such as vi or nano:

   sudo vi /etc/sysctl.conf

3. Add or modify the line `vm.max_map_count=262144` in the file.
4. Save and exit the file.
5. Apply the changes by running the following command:

   sudo sysctl -p

6. Verify that the value has been updated by running:

   sysctl vm.max_map_count

This will increase the `vm.max_map_count` value to the desired minimum value of `262144`.

max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144

这个错误信息是在启动Elasticsearch时出现的，它表示虚拟内存区域的最大映射数太低了，需要至少增加到262144。这个错误通常是由于操作系统的限制引起的，因为Elasticsearch需要更多的虚拟内存来运行。要解决这个问题，可以按照以下步骤进行操作：
1. 打开终端并以root用户身份登录。
2. 运行以下命令以永久性地增加vm.max_map_count的值：

   sysctl -w vm.max_map_count=262144

3. 如果您想在不重启系统的情况下立即更改vm.max_map_count的值，请运行以下命令：

   sysctl -w vm.max_map_count=262144

4. 如果您使用的是Docker容器，请在启动容器时添加以下参数：

   --sysctl vm.max_map_count=262144

这将在容器内部设置vm.max_map_count的值。

docker max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

To increase the `vm.max_map_count` value specifically for Docker, you can follow these steps:

1. Open a terminal and log in as the root user or use sudo for the following commands.
2. Create or edit the Docker daemon configuration file using a text editor such as vi or nano:

   sudo vi /etc/docker/daemon.json

3. Add the following configuration to the file:

   {
     "default-ulimits": {
       "memlock": {
         "Name": "memlock",
         "Hard": -1,
         "Soft": -1
       }
     }
   }

This configuration sets the memlock limit to unlimited, which is required to increase `vm.max_map_count` for Docker.
4. Save and exit the file.
5. Restart the Docker daemon to apply the changes:

   sudo systemctl restart docker

Once Docker restarts, it should have the increased `vm.max_map_count` value. You can verify this by running:

docker run --rm busybox sysctl vm.max_map_count

It should now show a value of at least `262144`.
