6 mysqld_safe_selinux - Security Enhanced Linux Policy for the
7 mysqld_safe processes
8
10 Security-Enhanced Linux secures the mysqld_safe processes via flexible
11 mandatory access control.
12 The mysqld_safe processes execute with the mysqld_safe_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep mysqld_safe_t
20
24 The mysqld_safe_t SELinux type can be entered via the
25 mysqld_safe_exec_t file type.
26 The default entrypoint paths for the mysqld_safe_t domain are the fol‐
28 lowing:
29 /usr/bin/mysqld_safe, /usr/bin/mariadbd-safe, /usr/libexec/mysqld_safe-
31 scl-helper
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 mysqld_safe policy is very flexible allowing users to setup their
41 mysqld_safe processes in as secure a method as possible.
42 The following process types are defined for mysqld_safe:
44 mysqld_safe_t
46 Note: semanage permissive -a mysqld_safe_t can be used to make the
48 process type mysqld_safe_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required.
55 mysqld_safe policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run mysqld_safe with the tight‐
57 est access possible.
58 If you want to dontaudit all daemons scheduling requests (setsched,
62 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
63 Enabled by default.
64 setsebool -P daemons_dontaudit_scheduling 1
66 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71 setsebool -P fips_mode 1
73 If you want to allow system to run with NIS, you must turn on the
77 nis_enabled boolean. Disabled by default.
78 setsebool -P nis_enabled 1
80
84 The SELinux process type mysqld_safe_t can manage files labeled with
85 the following file types. The paths listed are the default paths for
86 these file types. Note the processes UID still need to have DAC per‐
87 missions.

158 SELinux requires files to have an extended attribute to define the file
159 type.
160 You can see the context of a file using the -Z option to ls
162 Policy governs the access confined processes have to these files.
164 SELinux mysqld_safe policy is very flexible allowing users to setup
165 their mysqld_safe processes in as secure a method as possible.
166 STANDARD FILE CONTEXT
168 SELinux defines the file context types for the mysqld_safe, if you
170 wanted to store files with these types in a different paths, you need
171 to execute the semanage command to specify alternate labeling and then
172 use restorecon to put the labels on disk.
173 semanage fcontext -a -t mysqld_safe_exec_t '/srv/mysqld_safe/con‐
175 tent(/.*)?'
176 restorecon -R -v /srv/mymysqld_safe_content
177 Note: SELinux often uses regular expressions to specify labels that
179 match multiple files.
180 The following file types are defined for mysqld_safe:
182 mysqld_safe_exec_t
186 - Set files with the mysqld_safe_exec_t type, if you want to transition
188 an executable to the mysqld_safe_t domain.
189 Paths:
192 /usr/bin/mysqld_safe, /usr/bin/mariadbd-safe,
193 /usr/libexec/mysqld_safe-scl-helper
194 Note: File context can be temporarily modified with the chcon command.
197 If you want to permanently change the file context you need to use the
198 semanage fcontext command. This will modify the SELinux labeling data‐
199 base. You will need to use restorecon to apply the labels.
200
203 semanage fcontext can also be used to manipulate default file context
204 mappings.
205 semanage permissive can also be used to manipulate whether or not a
207 process type is permissive.
208 semanage module can also be used to enable/disable/install/remove pol‐
210 icy modules.
211 semanage boolean can also be used to manipulate the booleans
213 system-config-selinux is a GUI tool available to customize SELinux pol‐
216 icy settings.
