5.3. 使用默认 SSL 证书配置剩余的 Capsule 服务器以进行负载均衡

流程

1. 在 Satellite 服务器上，为 Capsule 服务器生成 Katello 证书：

   # capsule-certs-generate \
   --certs-tar "/root/capsule.example.com-certs.tar" \
   --foreman-proxy-cname loadbalancer.example.com \
   --foreman-proxy-fqdn capsule.example.com

   保留由 capsule-certs-generate 命令输出的示例 satellite-installer 命令的副本，用于安装 Capsule 服务器证书。

2. 将证书存档文件从 Satellite 服务器复制到 Capsule 服务器：

   # scp /root/capsule.example.com-certs.tar root@capsule.example.com:/root/capsule.example.com-certs.tar

3. 在 Capsule 服务器上，安装 puppetserver 软件包：

   # satellite-maintain packages install puppetserver

4. 在 Capsule 服务器上，为 puppet 证书创建目录：

   # mkdir -p /etc/puppetlabs/puppet/ssl/certs/ \
   /etc/puppetlabs/puppet/ssl/private_keys/ \
   /etc/puppetlabs/puppet/ssl/public_keys/

5. 在 Capsule 服务器上，从配置胶囊服务器的系统中复制此胶囊服务器的 Puppet 证书，以签署 Puppet 证书：

   # scp root@capsule-ca.example.com:/etc/puppetlabs/puppet/ssl/certs/capsule.example.com.pem /etc/puppetlabs/puppet/ssl/certs/capsule.example.com.pem
   # scp root@capsule-ca.example.com:/etc/puppetlabs/puppet/ssl/certs/ca.pem /etc/puppetlabs/puppet/ssl/certs/ca.pem
   # scp root@capsule-ca.example.com:/etc/puppetlabs/puppet/ssl/private_keys/capsule.example.com.pem /etc/puppetlabs/puppet/ssl/private_keys/capsule.example.com.pem
   # scp root@capsule-ca.example.com:/etc/puppetlabs/puppet/ssl/public_keys/capsule.example.com.pem /etc/puppetlabs/puppet/ssl/public_keys/capsule.example.com.pem

6. 在 Capsule 服务器上，将 /etc/puppetlabs/puppet/ssl/ 目录所有权改为用户 puppet 和组 puppet ：

   # chown -R puppet:puppet /etc/puppetlabs/puppet/ssl/

7. 在 Capsule 服务器上，为 /etc/puppetlabs/puppet/ssl/ 目录设置 SELinux 上下文：

   # restorecon -Rv /etc/puppetlabs/puppet/ssl/

8. 将以下选项附加到您从 capsule-certs-generate 命令的输出中获取的 satellite-installer 命令中：

   --certs-cname "loadbalancer.example.com" \
   --enable-foreman-proxy-plugin-remote-execution-script \
   --foreman-proxy-puppetca "false" \
   --puppet-ca-server "capsule-ca.example.com" \
   --puppet-dns-alt-names "loadbalancer.example.com" \
   --puppet-server-ca "false"

9. 在 Capsule 服务器上，输入 satellite-installer 命令：

   # satellite-installer --scenario capsule \
   --certs-cname "loadbalancer.example.com" \
   --certs-tar-file "capsule.example.com-certs.tar" \
   --enable-foreman-proxy-plugin-remote-execution-script \
   --foreman-proxy-foreman-base-url "https://satellite.example.com" \
   --foreman-proxy-oauth-consumer-key "oauth key" \
   --foreman-proxy-oauth-consumer-secret "oauth secret" \
   --foreman-proxy-puppetca "false" \
   --foreman-proxy-register-in-foreman "true" \
   --foreman-proxy-trusted-hosts "satellite.example.com" \
   --foreman-proxy-trusted-hosts "capsule.example.com" \
   --puppet-ca-server "capsule-ca.example.com" \
   --puppet-dns-alt-names "loadbalancer.example.com" \
   --puppet-server-ca "false"
