晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 sh-3ll

Note: The included SELinux policy files can be used for MariaDB Galera cluster.
However, since these policies had been tested for a limited set of scenarios,
it is highly recommended that you run mysqld in "permissive" mode even with
these policies installed and report any denials on mariadb.org/jira.


How to generate and load the policy module of MariaDB Galera cluster ?
  * Generate the SELinux policy module.
    # cd <source>/policy/selinux/
    # make -f /usr/share/selinux/devel/Makefile mariadb-server.pp

  * Load the generated policy module.
    # semodule -i /path/to/mariadb-server.pp

  * Lastly, run the following command to allow tcp/4568 and udp/4567.
    # semanage port -a -t mysqld_port_t -p tcp 4568
    # semanage port -a -t mysqld_port_t -p udp 4567

How to run mysqld in permissve mode ?
  # semanage permissive -a mysqld_t
