linux下安装letscertbot生成域名证书

linux下安装letscertbot生成域名证书

1.下载安装 certbot

1.1.使用 snap 方式安装certbot

# 安装 snap （jumpserver 会报警）
apt install snapd

# 卸载其他形式安装的 certbot
sudo apt-get remove certbot
sudo dnf remove certbot
sudo yum remove certbot

# install snap
sudo snap install --classic certbot
ln -s /snap/bin/certbot /usr/bin/
certbot --version

# 出现以下返回即可
------------------------
root@zuiyoujie:/opt# certbot --version
certbot 1.7.0
------------------------

1.2.使用脚本自动安装 certbot

  • 不容易成功
# get certbot install scripts
cd /opt/scripts
mkdir -p certbot-auto
wget https://dl.eff.org/certbot-auto
mv certbot-auto /usr/local/bin/certbot-auto
chown root /usr/local/bin/certbot-auto
chmod 0755 /usr/local/bin/certbot-auto
/usr/local/bin/certbot-auto --help

# import certbot key
wget -N https://dl.eff.org/certbot-auto.asc
gpg2 --keyserver pool.sks-keyservers.net --recv-key A2CFB51FA275A7286234E7B24D17C995CD9775F2
gpg2 --trusted-key 4D17C995CD9775F2 --verify certbot-auto.asc /usr/local/bin/certbot-auto

# 实例演示：
----------------------------------
root@zuiyoujie:/opt/scripts/certbot# gpg2 --keyserver pool.sks-keyservers.net --recv-key A2CFB51FA275A7286234E7B24D17C995CD9775F2
gpg: keybox '/root/.gnupg/pubring.kbx' created

gpg: /root/.gnupg/trustdb.gpg: trustdb created
gpg: key 4D17C995CD9775F2: public key "Let's Encrypt Client Team <letsencrypt-client@eff.org>" imported
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:               imported: 1

root@zuiyoujie:/opt/scripts/certbot-auto# gpg2 --trusted-key 4D17C995CD9775F2 --verify certbot-auto.asc /usr/local/bin/certbot-auto
gpg: Signature made Wed 05 Aug 2020 02:33:02 AM CST

gpg: next trustdb check due at 2027-11-22
gpg: Good signature from "Let's Encrypt Client Team <letsencrypt-client@eff.org>" [ultimate]            #  出现这个信息表示可以正常使用
-----------------------------------

# install certbot 
/usr/local/bin/certbot-auto

# 最后一步是创建 python 虚拟环境，比较耗时，且如果主机内存较小会报错
internal compiler error: Killed (program cc1)

# 执行以下命令，使用交换空间解决
sudo fallocate -l 1G /tmp/swapfile
sudo chmod 600 /tmp/swapfile
sudo mkswap /tmp/swapfile
sudo swapon /tmp/swapfile

# 之后清理掉交换空间
sudo swapoff /tmp/swapfile
sudo rm /tmp/swapfile

1.3.容器安装 certbot

sudo docker run -it --rm --name certbot \
            -v "/etc/letsencrypt:/etc/letsencrypt" \
            -v "/var/lib/letsencrypt:/var/lib/letsencrypt" \
            certbot/certbot certonly

1.4.apt 安装 certbot

# add PPA 
sudo apt-get install software-properties-common -y
sudo add-apt-repository universe
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update

# install certbot
sudo apt-get install certbot python3-certbot-nginx
certbot --version

# 如果是Apache 可以安装以下插件
sudo apt-get install python-certbot-apache

2.下载安装 letscertbot

cd /opt/scripts
git clone https://github.com/jinhucheung/letscertbot.git

## 修改aksk
cd letscertbot
cp config.json.example config.json
vim config.json
--------
your_email=
your_access_key_id=
your_access_key_secret=
--------

sed -i "s#your_email#$your_email#g" config.json
sed -i "s#your_access_key_id#$your_access_key_id#g" config.json
sed -i "s#your_access_key_secret#$your_access_key_secret#g" config.json

grep email config.json
grep access_key_id config.json
grep access_key_secret config.json

3.检测 DNS 的 API 配置

  • 测试是否可以正常修改阿里云的DNS解析配置
cd /opt/scripts/letscertbot
sudo python ./bin/manual.py --test --domain letscertbot.zuiyoujie.com --dns aliyun

---------------- 正确的返回----------------- 可以正常生成证书
root@zuiyoujie:/opt/scripts/letscertbot# sudo python ./bin/manual.py --test --domain letscertbot.zuiyoujie.com --dns aliyun
start to test letscertbot.zuiyoujie.com in DNS aliyun API
add TXT record(domain=zuiyoujie.com, rr=_acme-challenge.letscertbot, value=uJqSmGygc6iH3ApZ) to aliyun DNS
added TXT record
waiting 20 seconds...
remove above TXT record
removed TXT record
tested letscertbot.zuiyoujie.com in DNS aliyun API
-----------------------------------------------------

------------------  错误的返回 ----------- AKSK配置的权限有问题无法正确添加解析记录
root@zuiyoujie:/opt/scripts/letscertbot# sudo python ./bin/manual.py --test --domain letscertbot.zuiyoujie.com --dns aliyun
start to test letscertbot.zuiyoujie.com in DNS aliyun API
add TXT record(domain=zuiyoujie.com, rr=_acme-challenge.letscertbot, value=juXeSRP9mfC14Dop) to aliyun DNS
ERROR:logger:aliyun#__request raise urllib2.HTTPError: HTTP Error 400: Bad Request
HTTP Error 400: Bad Request
--------------------------------------------

4.生成域名证书

# 证书生成目录，软链接
ll /etc/letsencrypt/live/

# 证书文件目录
ll /etc/letsencrypt/archive/

python ./bin/obtain.py -d www.zuiyoujie.com --cert www.zuiyoujie.com 
python ./bin/obtain.py -d *.zuiyoujie.com --cert all.zuiyoujie.com

python ./bin/obtain.py -d *.39sky.com --cert all.39sky.com

python ./bin/obtain.py -d *.zuiyoujie.com --cert all.zuiyoujie.com --dns aliyun --challenge-alias _acme-challenge.zuiyoujie.com


-d 指定申请证书的域名
--cert 指定生成的证书文件的名称
  • 实例演示
-----------------------------------
root@zuiyoujie:/opt/scripts/letscertbot# python ./bin/obtain.py -d *.zuiyoujie.com --cert all.zuiyoujie.com
