mysql.te compilation

Postby naina_emmanuel » Wed Mar 23, 2016 5:37 am

Scenario: I had mysql policy module and in mysql.te file made some changes (commented some allow rules, bold in the code below) and then tried to reload it through <semodule. -R mysql.pp> but everytime I get the failed message. "failed on mysql.pp"
Even in my own created modules I get the failed message (not a base module) and i am using centos 7.
Please guide me through this.

Thanks in advance

Hi,

I tested this. Its reload without any issues.

Code: Select all
# echo "policy_module(mysql, 0.0.1)" > mysql.te;
# make -f /usr/share/selinux/devel/Makefile mysql.pp
# semodule -i mysql.pp
# semodule -l | grep mysql
mysql 0.0.1


In case you dont have Makefile;

Code: Select all
yum install selinux-policy-devel
CentOS
