What is the connection between httpd and mariadb server? Is it Unix
socket file? Or TCP socket?
In the case of TCP socket (port + host), it looks weird for httpd
going to read /var/lib/mysql/

Hi all,
I have a question about mysql relocation.
I already created an equivalency rule such as "semanage fcontext --list -C"
returns the following:
SELinux Local fcontext Equivalence
/mnt/lv_data/var/lib/mysql = /var/lib/mysql
Then I created a symlink in /var/lib:
system_u:object_r:mysqld_db_t:s0 26 May 17 14:39 mysql ->
/mnt/lv_data/var/lib/mysql
However, httpd/php can not connect to the database. The following message is
logged in audit.log:
type=AVC msg=audit(1684352064.936:232): avc: denied { read } for pid=8558
comm="httpd" name="mysql" dev="sda4" ino=147925
scontext=system_u:system_r:httpd_t:s0
tcontext=system_u:object_r:mysqld_db_t:s0 tclass=lnk_file permissive=0
My understanding is that httpd can not read the symlink. I expected to find
a boolean to allow this kind of access, to no avail.
So my question is: can I allow httpd symlink access without manually
modifying the actual policy (ie: using audit2allow and the likes)?
Thanks.
