On some of the Linux distribution SELinux is enabled by default, which may cause some unwanted issues, if you don’t understand how SELinux works and the fundamental details on how to configure it.
I strongly recommend that you understand SELinux and implement it on your environment. But, until you understand the implementation details of SELinux you may want to disable it to avoid some unnecessary issues.
To disable SELinux you can use any one of the 4 different methods mentioned in this article. The SELinux will enforce security policies including the mandatory access controls defined by the US Department of Defence using the Linux Security Module (LSM) defined in the Linux Kernel. Every files and process in the system will be tagged with specific labels that will be used by the SELinux. You can use Is -Z and view those labels as shown below:
# ls -Z /etc/ -rw-r--r-- root root system_u:object_r:etc_t:s0 a2ps.cfg -rw-r--r-- root root system_u:object_r:adjtime_t:s0 adjtime -rw-r--r-- root root system_u:object_r:etc_aliases_t:s0 aliases drwxr-x--- root root system_u:object_r:auditd_etc_t:s0 audit drwxr-xr-x root root system_u:object_r:etc_runtime_t:s0 blkid drwxr-xr-x root root system_u:object_r:bluetooth_conf_t:s0 bluetooth drwx------ root root system_u:object_r:system_cron_spool_t:s0 cron.d -rw-rw-r-- root disk system_u:object_r:amanda_dumpdates_t:s0 dumpdates See more suggestions on disabling here hope this helps! Still having problems then I will help but have a look. It comes defult so there's no way of blacking from installing.
