先执行以下命令（因为我在另一个终端执行，所以history的编号有重复）
7 wget https://pypi.python.org/packages/source/p/pycurl/pycurl-7.19.3.1.tar.gz --no-check-
8 tar -zxvf pycurl-7.19.3.1.tar.gz
9 cd pycurl-7.19.3.1/
10 ls
11 yum install python-devel gcc* libcurl-devel openssl-libs-1.0.2k-8.el7.x86_64 -y
12 kill -9 3688 #因为我yum被锁了
13 yum install python-devel gcc* libcurl-devel openssl-libs-1.0.2k-8.el7.x86_64 -y

1 ifconfig
2 ping www.baidu.com

4 systemctl restart network
5 ifconfig|grep 'inet '
6 ping 10.0.3.14
7 wget http://curl.haxx.se/download/curl-7.36.0.tar.gz
8 tar -zxvf curl-7.36.0.tar.gz
9 cd curl-7.36.0/
10 ls
11 ./configure
12 make && make install
13 export LD_LIBRARY_PATH=/usr/local/lib #这里也是关键，否则会报错ImportError: pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (none/other) 注意export，也就是说只能在当前终端有效，另开一个终端会失效
14 cd ..
15 cd pycurl-7.19.3.1/
16 ls
17 python setup.py install --curl-config=/usr/local/bin/curl-config
