起因
近期买了个新域名：屑.cc，一开始挂到了我在腾讯云的主服务器上，不过因为没备案，导致被腾讯云阻断。因为用的是tls加密，所以是直接重置链接，没有任何提示。
于是乎我想起了我那台搬瓦工的机器，挂在那里应该可以。当我尝试在宝塔面板后台安装php，他却报错了，显示如下：
checking for the location of libpng... yes
checking for the location of libXpm... no
checking for FreeType 2... /usr/local/freetype
checking whether to enable JIS-mapped Japanese font support in GD... no
configure: error: webp/decode.h not found.
make: *** No targets specified and no makefile found. Stop.
make: *** No rule to make target 'install'. Stop.

ERROR: php-7.3.17 install failed.
安装失败，请截图以上报错信息发帖至论坛www.bt.cn/bbs求助
初步尝试
一开始觉得很简单，不就少个库嘛，那装一下就好了
sudo apt-get install libwebp-dev
结果返回了个报错
root@ban-cn2:~# apt install libwebp-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libwebp-dev : Depends: libwebpdemux1 (= 0.4.4-1) but it is not going to be installed
linux-image-generic : Depends: linux-image-4.4.0-178-generic but it is not going to be installed or
linux-image-unsigned-4.4.0-178-generic but it is not going to be installed
Recommends: thermald but it is not going to be installed
linux-modules-extra-4.4.0-178-generic : Depends: linux-image-4.4.0-178-generic but it is not going to be installed or
linux-image-unsigned-4.4.0-178-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
尝试修复内核
这报错应该就是某次更新内核到一半停了？那修复下就好了嘛：
sudo apt --fix-broken install
结果又来了个报错

那就慢慢清理吧。。
先看看当前内核版本，然后把其他的都rm掉

又报错
这次报错是编译途中报错了，看看打印：
recipe for target 'Zend/zend_execute.lo' failed
看样子应该是内存不足，那就加1G的swap呗：
dd if=/dev/zero of=/swapfile bs=1024 count=1048576
mkswap /swapfile
swapon /swapfile
chown root:root /swapfile
chmod 0600 /swapfile
继续安装
最后当然装好了

清理战场
把前面新建的swap文件删了，释放空间，毕竟服务器就只剩2G可用空间了
swapoff /swapfile
rm -rf /swapfile
