Segmentation fault

It is possible that zlib was manually compiled and installed, and /etc/ld.so.conf was modified to include /usr/local/lab

The system has two versions of zlib, use ldconfig -v|grep libz to see the two versions of zlib.

 

[root@CMS-BAK:/usr/local/lib]# ldconfig -v|grep libz
ldconfig: Can’t stat /usr/local/lab/libevent-2.0.21-stable/lib: No such file or directory
libz.so.1 -> libz.so.1.2.5
libz.so.1 -> libz.so.1.2.3
[root@CMS-BAK:/usr/local/lib]# find/-name ‘libz.so.1’
/lib64/libz.so.1
/usr/local/lib/libz.so.1
/usr/local_bak/lib/libz.so.1
/usr/local_source/zlib-1.2.5/lib/libz.so.1

So, comment out the zlib in /etc/ld.so.conf.
[root@CMS-BAK:/data/mysql_data]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf

Execute ldconfig once

Execute yum clean all

yum install screen -y

Done!
