@Kefu Chai, I think you were looking for way to recreate httpd denial issue, it looks to be reproducible on atleast one of the config in ceph-deploy

There appear to be two problems here and I am only seeing the second in my runs.
This is a possible solution which works in my testing.

Let me know if you'd like me to create PRs for this patch.

SELinux is preventing /usr/bin/ceph-mgr from search access on the directory httpd. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that ceph-mgr should be allowed search access on the httpd directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'ceph-mgr' --raw | audit2allow -M my-cephmgr # semodule -i my-cephmgr.pp Additional Information: Source Context system_u:system_r:ceph_t:s0 Target Context system_u:object_r:httpd_config_t:s0 Target Objects httpd [ dir ] Source ceph-mgr Source Path /usr/bin/ceph-mgr Port <Unknown> Host <Unknown> Source RPM Packages ceph-mgr-14.2.7-437.geae77db.el7.x86_64 Target RPM Packages Policy RPM selinux-policy-3.13.1-252.el7_7.6.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name smithi093 Platform Linux smithi093 3.10.0-1062.12.1.el7.x86_64 #1 SMP Tue Feb 4 23:02:59 UTC 2020 x86_64 x86_64 Alert Count 1 First Seen 2020-02-10 03:15:07 UTC Last Seen 2020-02-10 03:15:07 UTC Local ID 2d39378a-4d3e-4733-aae2-a850a715f03c Raw Audit Messages type=AVC msg=audit(1581304507.733:6186): avc: denied { search } for pid=10709 comm="ceph-mgr" name="httpd" dev="sda1" ino=8790 scontext=system_u:system_r:ceph_t:s0 tcontext=system_u:object_r:httpd_config_t:s0 tclass=dir permissive=1 type=SYSCALL msg=audit(1581304507.733:6186): arch=x86_64 syscall=stat success=no exit=ENOENT a0=55f44cc957a0 a1=7fffe79dd0d0 a2=7fffe79dd0d0 a3=0 items=0 ppid=1 pid=10709 auid=4294967295 uid=167 gid=167 euid=167 suid=167 fsuid=167 egid=1 67 sgid=167 fsgid=167 tty=(none) ses=4294967295 comm=ceph-mgr exe=/usr/bin/ceph-mgr subj=system_u:system_r:ceph_t:s0 key=(null) Hash: ceph-mgr,ceph_t,httpd_config_t,dir,search
