功能

  1. https证书,免费版,每三个月续签一次,可以用过脚本自动续签

安装

  1. ssh登录到域名配置所在的主机(nginx,apache等)
  2. 安装git yum -y install git
  3. 输入 git clone https://github.com/letsencrypt/letsencrypt
  4. cd letsencrypt
  5. chmod +x letsencrypt-auto
  6. 安装证书:
    • ./letsencrypt-auto certonly –email 86533019@qq.com -d jenkins.jetbrains.org.cn
    • d参数后面对应的是域名,在执行的过程中,我遭遇了下面的报错: Total size: 44 M Downloading Packages: Running rpm_check_debug ERROR with rpm_check_debug vs depsolve: libgdbm.so.2()(64bit) is needed by python-libs-2.6.6-66.el6_8.x86_64 ** Found 7 pre-existing rpmdb problem(s), 'yum check' output follows: 4:perl-5.10.1-141.el6_7.1.x86_64 has missing requires of libgdbm.so.2()(64bit) 4:perl-devel-5.10.1-141.el6_7.1.x86_64 has missing requires of gdbm-devel polkit-0.96-5.el6_4.x86_64 has missing requires of libeggdbus-1.so.0()(64bit) 2:postfix-2.6.6-6.el6_5.x86_64 has missing requires of libmysqlclient.so.16()(64bit) 2:postfix-2.6.6-6.el6_5.x86_64 has missing requires of libmysqlclient.so. 16(libmysqlclient_16)(64bit) 2:postfix-2.6.6-6.el6_5.x86_64 has missing requires of mysql-libs python-libs-2.6.6-52.el6.x86_64 has missing requires of libgdbm.so.2()(64bit) Your transaction was saved, rerun it with: yum load-transactiontmp/.yum_save_tx-2017-04-07-22-1798AqLE.yumtx Could not install OS dependencies. Aborting bootstrap!
    • centos 6 需要安装 libgdbm.so.2:
      • wget http://mirror.centos.org/centos/6/os/x86_64/Packages/gdbm-1.8.0-39.el6.x86_64.rpm
      • yum localinstall gdbm-1.8.0-39.el6.x86_64.rpm
    • 完成后,重新执行上面的命令行:
  7. 即为安装完成

    配置

    1. web服务器,为这里是nginx,在nginx中添加代码:

       listen 443 ssl;
       ssl on;
       ssl_certificate /etc/letsencrypt/live/XXX.com/fullchain.pem;
       ssl_certificate_key /etc/letsencrypt/live/XXX.com/privkey.pem;
       ssl_protocols TLSv1 TLSv1.1 TLSv1.2; 
      
    2. 重启nginx,就可以放了https了 ##续约
    3. linux中执行 crontab -e
    4. 添加代码

      06 06 * * * /www/web/test/lets/certbot-master/certbot-auto renew --force-renewal --pre-hook "/etc/init.d/nginx stop" --post-hook "/etc/init.d/nginx start" >> /www/web_logs/letsencry.log 2>&1
