[Subtask]: update website documentation install guide

Parent Issue

Update server commands on MacOS: https://ragflow.io/docs/dev/

Documented commands do not work on Mac.

/etc/sysctl.conf folder/path do not exist on newer mac systems. To fix the same job, using the /Library/LaunchDaemons directory is needed.

Describe implementation you've considered

Change vm.max_map_count: docker run --rm --privileged --pid=host alpine sysctl -w vm.max_map_count=262144

The above command is not persistent and will reset at each reboot. To make it persistent, add new file with proper setting.

First create the file: sudo nano /Library/LaunchDaemons/com.user.vmmaxmap.plist

Open file to add settings: sudo launchctl load /Library/LaunchDaemons/com.user.vmmaxmap.plist

Adding XML configuration into file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>com.user.vmmaxmap</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/sbin/sysctl</string>
        <string>-w</string>
        <string>vm.max_map_count=262144</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
</dict>
</plist>

After saving the file, load the new daemon with the following command: sudo launchctl load /Library/LaunchDaemons/com.user.vmmaxmap.plist

In case it's useful, I found here another solution to use a container. I haven't tried it yet, but might be a nice way to implement without having to manually edit Mac system settings (if it works).

  fixsysctl:
    restart: "no"
    privileged: true
    deploy:
      replicas: 1
      resources:
        limits:
          memory: 25m
    image: centos:7
    command: "sysctl -w vm.max_map_count=262144"
