确保端口可用性

确保所需的端口可用。

Redis 企业软件

在安装 Redis Enterprise Software 之前，请确保所有必需的端口都可用。

如果 Redis 分配给数据库的端口正在作系统或其他进程使用，则安装将失败。

按照相关部分配置所需的端口。

有关推荐和可选的端口配置，请参阅网络端口配置。

更新sysctl.conf避免端口冲突

为避免端口冲突，请更新/etc/sysctl.conf包括：

net.ipv4.ip_local_port_range = 30000 65535

OS conflicts with port 53

If port 53 is in use, the installation fails. This issue can occur in default installations of certain operating systems in which systemd-resolved (DNS server) is running.

To prevent this issue, change the system configuration to make this port available before installation.

  1. Edit /etc/systemd/resolved.conf:

    sudo vi /etc/systemd/resolved.conf

  2. Add DNSStubListener=no as the last line in the file and save the file.

  3. Rename the current /etc/resolv.conf file:

    sudo mv /etc/resolv.conf /etc/resolv.conf.orig

  4. Create a symbolic link for /etc/resolv.conf:

    sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
    Note:
    You might encounter a temporary name resolution error (sudo: unable to resolve host {hostname}: Temporary failure in name resolution), which should be fixed when you restart systemd-resolved in the next step.

  5. Restart the DNS service:

    sudo service systemd-resolved restart
