域名添加HTTPS

准备

需要python版本为2.7以上,所以centos6需要把2.6升级成2.7

升级python

###安装python2.7
tar -xvf Python-2.7.5tar.bz2
cd Python2.7
./configure --prefix=/usr/local/python2.7 &&  make && make install

###安装python2.7对应的pip
wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-20.3.1.tar.gz
tar -xvf setuptools-20.3.1.tar.gz
cd setuptools-20.3.1
/usr/local/python2.7/bin/python2.7 setup.py install --prefix=/usr/local/python2.7
wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.1.tar.gz
tar -xvf pip-8.0.1.tar.gz
cd pip-8.0.1
/usr/local/python2.7/bin/python2.7 setup.py install --prefix=/usr/local/python2.7

迁移python

步骤:

把/usr/bin/python和pip改名为python2.6和pip2.6

mv /usr/bin/python /usr/bin/python2.6
mv /usr/bin/pip /usr/bin/pip2.6

修改yum配置文件指定python版本为python2.6

vim /usr/bin/yum
 #!/usr/bin/python 改为 #!/usr/bin/python2.6

把/usr/bin/python2.7和pip2.7改名为python和pip

ln -s  /usr//local/python2.7/bin/python2.7 /usr/bin/python
ln -s  /usr/local/python2.7/bin/pip2.7 /usr/bin/pip2.7

解释:因为yum需要依赖原来的python2.6

更改pip源

mkdir ~/.pip
cat > ~/.pip/pip.conf << EOF
[global]
trusted-host=mirrors.aliyun.com
index-url=http://mirrors.aliyun.com/pypi/simple/
EOF

利用Let's Encrypt 免费生成HTTPS证书

1. 下载安装certbot(Let's Encrypt )
2. 利用certbot生成证书
3. 配置nginx的https证书

安装cerbot

[root@hz1 ~]# wget https://dl.eff.org/certbot-auto
[root@hz1 ~]# chmod a+x certbot-auto
[root@hz1 ~]#./certbot-auto　　

利用certbot生成证书

给一个域名生成证书

[root@hz1 certbot]# ./certbot-auto certonly --email  zhai.junming@timecash.cn --agree-tos --webroot -w  /alidata1/www/timecash22/api3  -d  xxxx.zjm.cn
/root/.local/share/letsencrypt/lib/python2./site-packages/cryptography/__init__.py:: DeprecationWarning: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of cryptography will drop support for Python 2.6

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/xxx.zjm.cn/fullchain.pem. Your
   cert will expire on --. To obtain a new or tweaked version
   of this certificate in the future, simply run certbot-auto again.
   To non-interactively renew *all* of your certificates, run
   "certbot-auto renew"
 - If you like Certbot, please consider supporting our work by:

-w:指定域名的根目录
-d:指定域名

Note:证书已经生成到了/etc/letsencrypy/live/xxx.zjm.cn下

Nginx配置https证书

server {
    listen  ssl;
    ....
    ssl_certificate /etc/letsencrypt/live/xxx.zjm.cn/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/xxx.zjm.cn/privkey.pem;
    ssl_dhparam /etc/nginx/ssl/dhparam.pem;

}

ssl_certificate和ssl_certificate_key分别对应fullchain.pem,privkey.pem

ssl_dhparam通过以下命令生成

$ sudo mkdir /etc/nginx/ssl
$ sudo openssl dhparam -out /etc/nginx/ssl/dhparam.pem 

给多个域名生成一个证书,也就是多个域名使用一个ssl证书

./certbot-auto certonly --email admin@laobuluo.com --agree-tos --webroot -w /var/www/laozuo -d laozuo.org -d www.laozuo.org -w /var/www/laobuluo -d laobuluo.com -d www.laobuluo.com

迁移证书

需求:需要域名的解析IP变到另一台服务器了,需要把证书迁移过去

在原来服务器上吊销证书

 ./certbot-auto    revoke   --cert-path /etc/letsencrypt/live/app.wl.aaa.cn/fullchain.pem
#直接指定域名的证书路径就能吊销证书,千万不能直接删除

在新的服务器上重新申请证书

略

自动更新https证书

由于这个免费的证书只有90天的使用时间,所以遇到定时更新以下证书,这里是利用certbot每隔一段时间自动更新证书

手动执行更新

./certbot-auto  renew --dry-run

结合crontab每隔一段时间自动更新证书

  * *  ./certbot-auto  renew  >> /var/log/le-renew.log
