El semanaje el comando es un SELinux (Seguridad –Linux mejorado ) herramienta de administración que se utiliza para configurar elementos específicos sin realizar ningún ajuste o volver a ensamblar desde fuentes de políticas. Semanage consiste en mapear desde el nombre de usuario de Linux a las identidades de usuario de SELinux y también incluye mapear el contexto de seguridad para numerosos tipos de objetos como interfaz, puerto de red, etc.
Necesitas usar yum proporciona , esta opción para averiguar el paquete que proporciona el archivo consultado se llama /usr/sbin/semanage .

Complete!Intente ejecutar el comando semanage de nuevo, funcionará como magia.
También puede usar los siguientes comandos para obtener la página del manual en semanage command opciones y uso.
# man semanage
# semanage --helpTambién puedo verificar eso ejecutando mi setup-web.sh guión de nuevo.
[root@unixcop ~]# /usr/pgadmin4/bin/setup-web.sh
