Ubuntu环境编译Squid 5¶

准备¶

备注

我的编译工作是在私有云架构的私有云KVM环境进行的，采用 ref:libvirt_lvm_pool 中 clone虚拟机 脚本构建的编译虚拟机。

编译Squid需要大量磁盘空间，默认clone出来虚拟机6G磁盘(实际空闲空间不足3G)因容量不足，首次编译失败。所以，采用在libvirt LVM卷管理存储池中扩展虚拟机磁盘将虚拟机磁盘扩展到 16GB 以完成编译工作。

升级操作系统:

sudo apt update && sudo apt upgrade -y && sudo reboot

安装编译所需的工具:

sudo apt -y install devscripts build-essential fakeroot debhelper dh-autoreconf dh-apparmor cdbs

安装squid 5需要的的头文件包:

sudo apt -y install \
    libcppunit-dev \
    libsasl2-dev \
    libxml2-dev \
    libkrb5-dev \
    libdb-dev \
    libnetfilter-conntrack-dev \
    libexpat1-dev \
    libcap-dev \
    libldap2-dev \
    libpam0g-dev \
    libgnutls28-dev \
    libssl-dev \
    libdbi-perl \
    libecap3 \
    libecap3-dev \
    libsystemd-dev \
    libtdb-dev

编译Squid 5¶

源代码包是从 http://http.debian.net/debian/pool/main/s/squid/ 获取，所以查看该目录下可以确定最新版本是 5.2

创建配置文件 squid.ver :

编译squid 5脚本配置 squid.ver¶

#!/usr/bin/env bash

# set squid version
SQUID_VER="5.2"
SQUID_PKG="${SQUID_VER}-1"

编译脚本 build_squid.sh :

编译squid 5脚本: build_squid.sh¶

#!/bin/bash

if [[ $EUID -eq 0  ]]; then
      echo "This script must NOT be run as root" 1>&2
        exit 1
fi

# drop squid build folder
rm -R build/squid

# we will be working in a subfolder make it
mkdir -p build/squid

# set squid version
source squid.ver

# decend into working directory
pushd build/squid

# get squid from debian experimental
wget http://http.debian.net/debian/pool/main/s/squid/squid_${SQUID_PKG}.dsc
wget http://http.debian.net/debian/pool/main/s/squid/squid_${SQUID_VER}.orig.tar.xz
wget http://http.debian.net/debian/pool/main/s/squid/squid_${SQUID_VER}.orig.tar.xz.asc
wget http://http.debian.net/debian/pool/main/s/squid/squid_${SQUID_PKG}.debian.tar.xz

# unpack the source package
dpkg-source -x squid_${SQUID_PKG}.dsc

# build the package
cd squid-${SQUID_VER} && dpkg-buildpackage -rfakeroot -b -us -uc

# and revert
popd

执行编译:
```
./build_squid.sh
```
安装脚本 install_squid.sh :

安装squid 5脚本: install_squid.sh¶

#!/bin/bash

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

# set squid version
source squid.ver

# decend into working directory
pushd build/squid

# install squid packages
sudo apt-get install squid-langpack
dpkg --install squid-common_${SQUID_PKG}_all.deb
dpkg --install squid-openssl_${SQUID_PKG}_amd64.deb
dpkg --install squidclient_${SQUID_PKG}_amd64.deb

# and revert
popd

# verify the installed squid binary
systemctl stop squid && systemctl start squid && systemctl status squid && /usr/sbin/squid -v

执行安装:
```
./install_squid.sh
```
