1、更新yum  这里可能更新时间有点长,,稳住~别急
yum -y upgrade
2、安装 epel-release 这个必须先安装,因为: python-pip 和 privoxy 都在EPEL源里面,, 有的小伙伴可能已经换了国内的源,所以请先检查安装这两个包,以防不测(万一你换的源里没有呢()^_^)
yum install -y epel-release
3、安装 python-pip
yum install -y python-pip

#安装完成后需要更新一下

pip install --upgrade pip
4、安装 shadowsocks 、安装
#install ss
pip install shadowsocks
#install privoxy
yum install -y privoxy

vim /etc/shadowsocks.json
添加以下内容
{
    "server": "156.12.22.29",
    "server_port": "55555",
    "local_address": "127.0.0.1",
    "local_port": "6666",
    "password": "service_password",
    "method": "aes-256-cfb",
    "timeout": "300",
    "workers": "1"
}

每个字段解释

  server :: shadowsocks服务器的ip   server_port :: shadowsocks服务器端口   local_address :: 本机监听地址,不需要修改   local_port :: 本机监听端口,不要和正在使用的端口冲突   password :: shadowsocks服务器密码   method :: shadowsocks服务器的加密方式   6、配置 privoxy
vim /etc/privoxy/config
# 确认下面这一行没有被注释掉 listen-address 127.0.0.1:8118 ## 默认端口是8118,不需要修改
# 新增一行 forward-socks5t / 127.0.0.1:6666 .
## 端口必须与 /etc/shadowsocks.json 中 local_port 字段的值相同,
## 注意:行尾有一个英文句号(.)

 

7、启动 shadowsocks+ 测试
# 以 daemon 模式启动 
[root@centos-linux ~]# sslocal -c /etc/shadowsocks.json -d start
INFO: loading config from /etc/shadowsocks.json
2019-02-26 23:30:12 INFO loading libcrypto from libcrypto.so.10
started
# 确认 sslocal 已监听在预设端口 lsof -i | grep sslocal
[root@centos-linux ~]# lsof -i | grep sslocal
sslocal 24367 root 4u IPv4 53001198 0t0 TCP localhost:ircu-2 (LISTEN)
sslocal 24367 root 5u IPv4 53001199 0t0 UDP localhost:ircu-2
[root@centos-linux ~]# curl --socks5 127.0.0.1:6666 http://httpbin.org/ip
{
"origin": "156.12.22.29, 156.12.22.29" # 注意 :: 必须与 /etc/shadowsocks.json 中 server 字段的值相同
}
  8、启动 privoxy +测试
systemctl start privoxy
[root@centos-linux ~]# curl --proxy https://127.0.0.1:8118 -Is https://google.com | grep -w 200
HTTP/1.1 200 Connection established
9、设置开机启动
sh -c 'echo "sudo /usr/bin/sslocal -c /etc/shadowsocks.json -d start" >> /etc/rc.d/rc.local' # 如果 rc.local 没有可执行权限就给它加上
systemctl enable privoxy
10、测试是否能科学上网  
#启用代理
export http_proxy='127.0.0.1:8118'
export https_proxy='127.0.0.1:8118'

# 停用代理
export http_proxy=''
export https_proxy=''
curl -I https://golang.org/
#执行命令后出现如下信息,说明成功
[root@centos-linux ~]# curl -I https://golang.org/
HTTP/1.1 200 Connection established
 
HTTP/1.1 200 OK

  11、为了更方便使用,启动和停用写成一个shell脚本
#创建文件 /etc/profile.d/vm-proxy.sh,文件内容如下
[root@centos-linux ~]# cat /etc/profile.d/vm-proxy.sh
function cmd-proxy-on {
export no_proxy="127.0.0.1,localhost,localaddress,.localdomain.com,tencentyun.com";
export http_proxy='127.0.0.1:8118';
export https_proxy=$http_proxy;
echo 'HTTP proxy started.'
}
export -f cmd-proxy-on

# 第二种声明函数的方式
cmd-proxy-off() {
unset http_proxy;
unset https_proxy;
echo 'HTTP proxy stopped.'
}
export -f cmd-proxy-off
#source 脚本
chmod +x /etc/profile.d/vm-proxy.sh
source /etc/profile.d/vm-proxy.sh
  最后测试脚本
[root@centos-linux ~]# vim /etc/profile.d/vm-proxy.sh
[root@centos-linux ~]# chmod +x /etc/profile.d/vm-proxy.sh
[root@centos-linux ~]# source /etc/profile.d/vm-proxy.sh
[root@centos-linux ~]# cmd-proxy-on
HTTP proxy started.
[root@centos-linux ~]# curl -I https://golang.org/
HTTP/1.1 200 Connection established
 
HTTP/1.1 200 OK

[root@centos-linux ~]# cmd-proxy-off
HTTP proxy stopped.
[root@centos-linux ~]# curl -I https://golang.org/
 
curl: (7) Failed connect to golang.org:443; 拒绝连接
