mongodb install error: mongod: error while loading shared libraries: liblzma.so.0: cannot open shared object file: No such file or directory
Screeshots:

Solution:
1. Modify the /etc/profile file
Check the environment variables, however, no error was found
2. Modify the /etc/ld.so.conf file

1. After adding /usr/local/lib to /etc/ld.so.conf, I found that there is no liblzma.so.0 in this directory, only liblzma.so.5

2. At the command line, type sudo find / -name liblzma.so.0* -type f and find that liblzma.so.0 is not found

3. Type yum install xz-compat-libs on the command line to download liblzma.so.0

4. OK!
