export http_proxy="http://172.16.13.14:10811/"
export https_proxy="http://172.16.13.14:10811/"
export ftp_proxy="http://172.16.13.14:10811/"
export no_proxy="127.0.0.1,localhost,172.16.13.*"
# For curl
export HTTP_PROXY="http://172.16.13.14:10811/"
export HTTPS_PROXY="http://172.16.13.14:10811/"
export FTP_PROXY="http://172.16.13.14:10811/"
export NO_PROXY="127.0.0.1,localhost,172.16.13.*"

添加执行权限

sudo chmod +x  /etc/profile.d/proxy.sh
