示例配置

创建目录

$ sudo mkdir /etc/custodia /var/lib/custodia /var/log/custodia /var/run/custodia
$ sudo chown USER:GROUP /var/lib/custodia /var/log/custodia /var/run/custodia
$ sudo chmod 750 /var/lib/custodia /var/log/custodia

创建服务帐户和keytab

$ kinit admin
$ ipa service-add custodia/$HOSTNAME
$ ipa service-allow-create-keytab custodia/$HOSTNAME --users=admin
$ mkdir -p /etc/custodia
$ ipa-getkeytab -p custodia/$HOSTNAME -k /etc/custodia/ipa.keytab
$ chown custodia:custodia /etc/custodia/ipa.keytab

IPA证书请求插件需要其他权限

$ ipa privilege-add \
    --desc="Create and request service certs with Custodia" \
    "Custodia Service Certs"
$ ipa privilege-add-permission \
    --permissions="Retrieve Certificates from the CA" \
    --permissions="Request Certificate" \
    --permissions="Revoke Certificate" \
    --permissions="System: Modify Services" \
    "Custodia Service Certs"
# for add_principal=True
$ ipa privilege-add-permission \
    --permissions="System: Add Services" \
    "Custodia Service Certs"
$ ipa role-add \
    --desc="Create and request service certs with Custodia" \
    "Custodia Service Cert Adminstrator"
$ ipa role-add-privilege \
    --privileges="Custodia Service Certs" \
    "Custodia Service Cert Adminstrator"
$ ipa role-add-member \
    --services="custodia/$HOSTNAME" \
    "Custodia Service Cert Adminstrator"

创建/etc/custodia/ipa.conf

# /etc/custodia/ipa.conf

[global]
debug = true
makedirs = true

[auth:ipa]
handler = IPAInterface
keytab = ${configdir}/${instance}.keytab
ccache = FILE:${rundir}/ccache

[auth:creds]
handler = SimpleCredsAuth
uid = root
gid = root

[authz:paths]
handler = SimplePathAuthz
paths = /. /secrets

[store:vault]
handler = IPAVault

[store:cert]
handler = IPACertRequest
backing_store = vault

[/]
handler = Root

[/secrets]
handler = Secrets
store = vault

[/secrets/certs]
handler = Secrets
store = cert

运行custodia服务器

$ systemctl start custodia@ipa.socket

IPA证书请求

ipacertrequest存储插件在上生成或撤消证书 苍蝇。它使用备份存储来缓存证书和私钥。这个 插件可以自动创建服务主体。但是主人必须 已经存在。ipacertrequest不在 需求。

像GET /path/to/store/HTTP/client1.ipa.example这样的请求生成 服务HTTP/client1.ipa.example的私钥和csr DNS使用者替代名称^{TT5}$。企业社会责任就是 转发给IPA并由Dogtag签名。结果证书及其信任 链作为pem包与私钥一起返回。

$ export CUSTODIA_INSTANCE=ipa
$ custodia-cli get /certs/HTTP/client1.ipa.example
-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----

delete请求将证书/密钥对从备份存储中删除，并 同时撤消证书。
