Squid5.2/5.6 https proxy Ubuntu20 中间人 代理折腾大全

系统是ubuntu-20.04.4-live-server-amd64，Openssl版本是OpenSSL 1.1.1f 31 Mar 2020。VM虚拟机记得到配置文件写入 disk.EnableUUID = "TRUE"

1，把如下代码保存成sh可执行文件，并执行。自行生成证书文件

openssl req -new -newkey rsa:2048 -sha256 -days 365 -nodes -x509 -extensions v3_ca -keyout squid-ca-key.pem -out squid-ca-cert.pem

cat squid-ca-cert.pem squid-ca-key.pem >> squid-ca-cert-key.pem
#!/bin/bash

# all packages are installed as root
if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

# add diladele apt key
wget -qO - https://packages.diladele.com/diladele_pub.asc | sudo apt-key add -

# add new repo
echo "deb https://squid52.diladele.com/ubuntu/ focal main" \
    > /etc/apt/sources.list.d/squid52.diladele.com.list

# and install
apt-get update && apt-get install -y \
    squid-common \
    squid-openssl \
    squidclient \
    libecap3 libecap3-dev
systemctl daemon-reload

2，查看是否包含–enable-ssl-crtd。执行 squid -v

3，配置 squid.conf

acl localnet src 172.16.0.0/12  # RFC1918 possible internal network

http_access deny manager

# Deny requests to certain unsafe ports

# Deny CONNECT to other than secure SSL ports
http_access deny CONNECT !SSL_ports


http_access allow localnet
http_access allow localhost
# And finally deny all other access to this proxy
http_access deny all

# Squid normally listens to port 3128

# Uncomment the line below to enable disk caching - path format is /cygdrive/<full path to cache folder>, i.e.

# Leave coredumps in the first cache dir
coredump_dir /squid/dump

# Add any of your own refresh_pattern entries above these.

dns_nameservers 8.8.8.8 8.8.4.4

4，启动前先初始化一个项目，否则无法启动

sudo /usr/lib/squid/security_file_certgen -c -s /var/spool/squid/ssl_db -M 4MB

5，这里就可以完全启动了。自行测试下用如下命令

curl --proxy http://127.0.0.1:3218 --cacert squid-ca-cert.pem https://www.baidu.com

这时候，你可以vi打开squid-ca-cert.pem，复制里面的内容到 查错网 转换下证书格式为 cer，下载到Windows。双击打开安装到“可信任的证书颁发机构”，设置 Internet选项-连接-局域网代理 设置代理地址为这个Ubuntu机器的IP地址，端口设置为 3128 。至此打开百度，你可以在/var/log/syslog看到你访问的日志记录了。

6,尴尬了，这个5.2的容易崩溃。看下面编译5.6的
