Linux升级lib64中的libc.so.6导致所有命令失效

jerry-892024-08-21 14:46

ls: relocation error: libpthread.so.0: symbol __libc_dl_error_tsd, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

升级Glibc后出现所有shell命令都不可用

复制代码

# systemctl status
systemctl: relocation error: /lib64/libpthread.so.0: symbol __libc_vfork version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference
# systemctl status kubelet
systemctl: relocation error: /lib64/libpthread.so.0: symbol __libc_vfork version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference
# ps
ps: relocation error: /lib64/libpthread.so.0: symbol __libc_vfork version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference
# ps -elf
ps: relocation error: /lib64/libpthread.so.0: symbol __libc_vfork version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference
# ls
ls: relocation error: /lib64/libpthread.so.0: symbol __libc_vfork version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

解决方法

原因是因为升级过程删除了soft link

此时，sln命令还是可以用的

复制代码

# sln /usr/lib64/libc-2.28.so /lib64/libc.so.6 
# sln /usr/lib64/ld-2.28.so /usr/lib64/ld-linux-x86-64.so.2

系统恢复正常

复制代码
