ubuntu 20升级glibc版本到2.33做法(危险！请勿尝试，可能导致kernel panic)
查看glibc当前版本：
# ldd --version
# ls -l /lib/x86_64-linux-gnu/libc.so.6
lrwxrwxrwx 1 root root 12 Dec 16 2020 /lib/x86_64-linux-gnu/libc.so.6 -> libc-2.31.so
# strings /lib/x86_64-linux-gnu/libc.so.6 |grep GLIBC_
查看各发行本glibc最高版本
https://pkgs.org/download/glibc
https://www.ubuntuupdates.org/package/core/hirsute/universe/base/glibc
https://tracker.debian.org/pkg/glibc
警告：Please do not attempt to update glibc outside of yum or using foreign, non-CentOS, packages. You will break your system to the reinstall point if you try.
# ln -s /usr/include/x86_64-linux-gnu/asm /usr/include/asm
# wget
http://ftp.gnu.org/gnu/glibc/glibc-2.33.tar.gz
# tar -xvf glibc-2.33.tar.gz
# cd glibc-2.33
# mkdir build; cd build
# ../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
# make
# make install （危险！，参考
https://sourceware.org/glibc/wiki/Testing/Builds）
执行新ldconfig（Inconsistency detected by ld.so: dl-call-libc-early-init.c: 37: _dl_call_libc_early_init: Assertion `sym != NULL' failed!）
# /sbin/ldconfig
查看版本，发现已升级到2.33版本
# ldd --version
ldd (GNU libc) 2.33
# ldconfig -p|grep libc.so.6
libc.so.6 (libc6,x86-64, OS ABI: Linux 3.2.0) => /lib64/libc.so.6
# ls -l /lib64/libc.so.6
lrwxrwxrwx 1 root root 12 Jul 19 12:06 /lib64/libc.so.6 -> libc-2.33.so
# strings /lib64/libc-2.33.so |grep GLIBC_
# ls -l /lib64/libc-2.33.so
