One, SELinux configurationIn order for Cloudstack to work properly, we must set the SELinux to permissive. It needs to be available in the current system running state and after it has been started, with the following configuration.To set SELinux to permissive while the system is running, execute the following command:Setenforce 0Configure the/etc/selinux/config file according to the following Lezilai to ensure that the current SELinux status is permissive.

Article Title: system time synchronization and ntp service provision. Linux is a technology channel of the IT lab in China. Some basic classification computers, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems, will experience errors soon if they are left blank. This error is reflected in the time s

Time synchronization in a cluster can cause big data applications to run into confusion, causing unpredictable problems, such as HBase, which hangs when time differences are too large, so in a big data cluster, the NTP service should serve as a basic service, as shown below in the CentOS 7.2 Procedures for configuring NTP
