容器化 SUSE Multi-Linux Manager Proxy 设置
为 SUSE Multi-Linux Manager Proxy 容器准备好容器主机后,需要额外执行几步容器设置才能完成配置。
-
生成 SUSE Multi-Linux Manager Proxy 配置归档文件
-
将配置归档传输到在安装步骤中准备的容器主机并解压缩
-
Start the proxy sevices with
mgrpxy
1. 生成代理配置
SUSE Multi-Linux Manager 代理的配置归档由 SUSE Multi-Linux Manager 服务器生成。每个附加代理都需要自身的配置归档。
对于容器化 SUSE Multi-Linux Manager 代理,您必须构建新的代理配置文件,然后重新部署容器以使更改生效。此流程适用于更新设置(包括 SSL 证书)。
|
对于 Podman 部署,在生成此代理配置之前,必须将 SUSE Multi-Linux Manager 代理的容器主机作为客户端注册到 SUSE Multi-Linux Manager 服务器。 |
If a proxy FQDN is used to generate a proxy container configuration that is not a registered client (as in the Kubernetes use case), a new system entry will appear in system list. This new entry will be shown under previously entered Proxy FQDN value and will be of Foreign system type.

外围服务器始终使用第三方 SSL 证书。如果中心服务器已为外围服务器生成证书,则还需为外围数据库生成证书。在中心服务器上,为每台待迁移的外围服务器运行以下命令。
需要使用的文件包括:

1.1. 使用 Web UI 生成代理配置
在 Web UI 中,导航到,然后填写所需数据。
In the
Proxy FQDNfield type fully qualified domain name for the proxy.In the
Parent FQDNfield type fully qualified domain name for the SUSE Multi-Linux Manager Server or another SUSE Multi-Linux Manager Proxy.In the
Proxy SSH portfield type SSH port on which SSH service is listening on SUSE Multi-Linux Manager Proxy. Recommended is to keep default 8022.In the
Max Squid cache size [MB]field type maximal allowed size for Squid cache. Recommended is to use at most 80% of available storage for the containers.
2 GB 表示默认的代理 squid 缓存大小。需要根据您的环境调整此大小。
In the
SSL certificateselection list choose if new server certificate should be generated for SUSE Multi-Linux Manager Proxy or an existing one should be used. You can consider generated certificates as SUSE Multi-Linux Manager builtin (self signed) certificates.+
然后根据所做的选择提供用于生成新证书的签名 CA 证书的路径,或者要用作代理证书的现有证书及其密钥的路径。
+
The CA certificates generated by the server are stored in the
/var/lib/containers/storage/volumes/root/_data/ssl-builddirectory.+
有关现有或自定义证书的详细信息以及企业和中间证书的概念,请参见 导入 SSL 证书。
Click Generate to register a new proxy FQDN in the SUSE Multi-Linux Manager Server and generate a configuration archive (
config.tar.gz) containing details for the container host.片刻之后,系统会显示文件可供下载。请将此文件保存在本地。
1.2. Generate Proxy Configuration With spacecmd and Self-Signed Certificate
You can generate a Proxy configuration using spacecmd.
通过 SSH 连接到您的容器主机。
执行以下命令(替换其中的服务器和代理 FQDN):
mgrctl exec -ti 'spacecmd proxy_container_config_generate_cert -- dev-pxy.example.com dev-srv.example.com 2048 email@example.com -o /tmp/config.tar.gz'从服务器容器复制生成的配置:
mgrctl cp server:/tmp/config.tar.gz .
1.3. Generate Proxy Configuration With spacecmd and Custom Certificate
You can generate a Proxy configuration using spacecmd for custom certificates rather than the default self-signed certificates.
通过 SSH 连接到您的服务器容器主机。
执行以下命令(替换其中的服务器和代理 FQDN):
for f in ca.crt proxy.crt proxy.key; do mgrctl cp $f server:/tmp/$f done mgrctl exec -ti 'spacecmd proxy_container_config -- -p 8022 pxy.example.com srv.example.com 2048 email@example.com /tmp/ca.crt /tmp/proxy.crt /tmp/proxy.key -o /tmp/config.tar.gz'如果您的设置使用中间 CA,请同时复制该证书,并在命令中通过
-i选项(可根据需要多次提供)包含该证书:mgrctl cp intermediateCA.pem server:/tmp/intermediateCA.pem mgrctl exec -ti 'spacecmd proxy_container_config -- -p 8022 -i /tmp/intermediateCA.pem pxy.example.com srv.example.com 2048 email@example.com /tmp/ca.crt /tmp/proxy.crt /tmp/proxy.key -o /tmp/config.tar.gz'从服务器容器复制生成的配置:
mgrctl cp server:/tmp/config.tar.gz .
2. 传输 SUSE Multi-Linux Manager 代理配置
Both spacecmd command and generating via Web UI ways create a configuration archive. This archive needs to be made available on container host. Transfer this generated archive to the container host.
3. 启动 SUSE Multi-Linux Manager 代理容器
Container can be started with the mgrpxy command.
-
运行以下命令:
mgrpxy start uyuni-proxy-pod
-
调用以下命令检查所有容器是否都已按预期启动:
podman ps
Five SUSE Multi-Linux Manager Proxy containers should be present and should be part of proxy-pod container pod.
-
proxy-salt-broker
-
proxy-httpd
-
proxy-tftpd
-
proxy-squid
-
proxy-ssh
