如何让Gitweb使用SELinux（在CentOS 6.5上，使用gitolite v3）

Question

I have installed gitolite and gitweb according to the tutorial in this blog post . The whole thing runs really good. I am able to clone and commit to the server.

However, Gitweb shows no project with the error code 404 - No projects found . I discovered that SELinux denied gitweb.cgi from accessing some files. Gitweb is able to show the repositories only after putting SELinux into permissive mode.

# setenforce 0

I have already tried many solutions from a few sites, but I found none of them work for me. For example, I have tried the solution introduced in this blog post .

# semanage fcontext -a -t httpd_sys_content_t /var/lib/gitolite/projects.list
# restorecon -v /var/lib/gitolite/projects.list

I have the following SELinux log but I really have no ideas what to do with it. I have already messing with this problem for a whole day, any suggestions are appreciated. Thanks in advance

You would change the default context for any of files or subdirectories in '/var/lib/gitolite', not only projects.list.

# semanage fcontext -a -t httpd_sys_content_t "/var/lib/gitolite(/.*)?"
# restorecon -v /var/lib/gitolite
