System

The system page provides management features for basic server configuration, including DNS, SWAP, hostname, and time settings.

DNS

Configure the system's DNS servers.

Configuration Items

• DNS1: Primary DNS server address
• DNS2: Secondary DNS server address

Common DNS Servers

Provider	DNS1	DNS2
Alibaba Cloud	223.5.5.5	223.6.6.6
Tencent Cloud	119.29.29.29	119.28.28.28
114 DNS	114.114.114.114	114.114.115.115
Google	8.8.8.8	8.8.4.4
Cloudflare	1.1.1.1	1.0.0.1

SWAP

Manage the system's SWAP space.

The page displays current SWAP usage:

• System total
• Used
• Available

Configure Panel SWAP

Set the size of the SWAP file managed by the panel (unit: MB).

• Setting to 0 disables panel SWAP
• It is recommended to set based on server memory size, typically 1-2 times the memory

Tip

SWAP can provide additional virtual memory when physical memory is insufficient, but performance is lower than physical memory. For servers with sufficient memory, SWAP may not need to be enabled.

Host

Configure system hostname and Hosts file.

System Hostname

Modify the server's hostname, such as myserver, web-01, etc.

Hosts

Edit the system's /etc/hosts file for configuring local domain name resolution.

Common uses:

• Block specific domains
• Configure local development domains
• Speed up resolution of specific domains

Time

Configure system timezone and time synchronization.

Select Timezone

Select the server's timezone from the dropdown list, such as Asia/Shanghai.

Modify Time

Manually set the system time.

Note

After manually changing the time, automatic system time synchronization may still override the settings.

NTP Server

Configure the NTP time synchronization server. Leave empty to use the system default server.

Common NTP servers:

• ntp.aliyun.com - Alibaba Cloud
• ntp.tencent.com - Tencent Cloud
• cn.pool.ntp.org - China NTP Pool

Action Buttons

• Configure Default Server: Restore to using the system default NTP server
• Save: Save timezone and time settings
• Sync Time: Immediately synchronize time with the NTP server
