环境 系统平台Linux x86-64 Red Hat Enterprise Linux 7 版本14 文档用途 本文主要介绍Patroni架构中如何开启etcd的ssl证书认证。
详细信息
一、前提说明
patroni版本3.0.2
etcd版本3.5.7
数据库版本14.4
OS版本redhat7.7
二、自签名CA证书及私钥
1、私钥生成
[rootpatroni8 ssl]# openssl genrsa -out ca-key.pem 2048
Generating RSA private key, 2048 bit long modulus
.....................................
.............................
e is 65537 (0x10001)2、自签名证书生成
填写以下内容其余的回车跳过
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:SD
Locality Name (eg, city) [Default City]:JN
Common Name (eg, your name or your server’s hostname) []:etcd
[rootpatroni8 ssl]# openssl req -new -x509 -key ca-key.pem -out ca.pem -days 365
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter ., the field will be left blank.
-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:SD
Locality Name (eg, city) [Default City]:JN
Organization Name (eg, company) [Default Company Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (eg, your name or your servers hostname) []:etcd
Email Address []:
[rootpatroni8 ssl]# ls
ca-key.pem ca.pem3、etcd私钥生成
[rootpatroni8 ssl]# openssl genrsa -out server-key.pem 2048
Generating RSA private key, 2048 bit long modulus
.....

e is 65537 (0x10001)4、编辑配置文件生成etcd证书
[rootpatroni8 ssl]# vi openssl.cnf
[req]
distinguished_name req_distinguished_name
req_extensions v3_req
prompt no
[req_distinguished_name]
C CN
ST SD
L JN
CN etcd
[v3_req]
subjectAltName alt_names
[alt_names]
IP.1 192.168.11.16
IP.2 192.168.11.17
IP.3 192.168.11.185、生成etcd证书
[rootpatroni8 ssl]# openssl req -new -key server-key.pem -out server.csr -subj /CNetcd-server -config openssl.cnf
[rootpatroni8 ssl]# ls
ca-key.pem ca.pem openssl.cnf server.csr server-key.pem
[rootpatroni8 ssl]# openssl x509 -req -in server.csr -CA ca.pem -CAkey ca-key.pem -CAcreateserial -out server.pem -days 365 -extensi ons v3_req -extfile openssl.cnf
Signature ok
subject/CCN/STSD/LJN/CNetcd
Getting CA Private Key
[rootpatroni8 ssl]# ls
ca-key.pem ca.pem ca.srl openssl.cnf server.csr server-key.pem server.pem
[rootpatroni8 ssl]# ls -lrth
total 28K
-rw-r--r--. 1 root root 1.7K May 15 11:20 ca-key.pem
-rw-r--r--. 1 root root 1.3K May 15 11:28 ca.pem
-rw-r--r--. 1 root root 1.7K May 15 11:29 server-key.pem
-rw-r--r--. 1 root root 255 May 15 11:33 openssl.cnf
-rw-r--r--. 1 root root 1001 May 15 11:33 server.csr
-rw-r--r--. 1 root root 17 May 15 11:34 ca.srl
-rw-r--r--. 1 root root 1.2K May 15 11:34 server.pem6、将私钥证书复制到其他节点
[rootpatroni8 ssl]# scp ca-key.pem ca.pem server.pem server-key.pem root192.168.11.17:/opt/etcd/ssl
[rootpatroni8 ssl]# scp ca-key.pem ca.pem server.pem server-key.pem root192.168.11.16:/opt/etcd/ssl7、修改各节点etcd配置文件将http换为https
编辑/opt/etcd/etcd.yaml文件
debug: false
name: etcd03
data-dir: /opt/etcd/data
initial-advertise-peer-urls: https://192.168.11.18:2380

[rootpatroni8 ssl]# systemctl start etcd
验证etcd开启tls
[rootpatroni6 etcd]# etcdctl --endpointshttps://192.168.11.16:2379,https://192.168.11.17:2379,https://192.168.11.18:2379 --cacert/opt/etcd/ssl/ca.pem --cert/opt/etcd/ssl/server.pem --key/opt/etcd/ssl/server-key.pem endpoint health

cluster is healthy三、patroni配置ssl
1、配置patroni文件中的etcd部分
etcd:#配置etcd所有节点的访问IP及端口hosts: 192.168.11.16:2379,192.168.11.17:2379,192.168.11.18:2379protocol: httpscert: /opt/etcd/ssl/server.pemkey: /opt/etcd/ssl/server-key.pemcacert: /opt/etcd/ssl/ca.pem
# username: root
# password: 1234562、启动patroni
systemctl start patroni四、注意事项
1、如果报错是CA是自签名的不可信需要将证书添加到可信存储中每个节点都执行
cp ca.pem /etc/pki/ca-trust/source/anchors/update-ca-trust
