   sometimes in linux do not know what services service, for example, you want to restart the mysql service, but I do not know whether this service mysql on linux, you can use this method to do

   service service name status
   example you want to see if this service mysql on linux, two-step process:

   step 1:
   see if this process mysql

   -ef PS | grep MySQL
   the STEP 2:
   Check the status of the service:

   service mysqld status
   if they can see the service status, it shows there is this Service

2. The step of modifying vsftpd complete configuration file (root user):

   service vsftpd stop
   vim /etc/vsftpd.conf
   service xinetd restart
   service vsftpd start

   Note that vsftpd configuration file required user groups and owners are root, so if not, you need to modify the following command:

   sudo chown root /etc/vsftpd.conf
   sudo chgrp root /etc/vsftpd.conf

3. vsftpd law two operation modes

   Source: https://www.cnblogs.com/tuteng/articles/2953034.html

   Like other daemons, like, vsftpd provides standalone and inetd (inetd or xinetd) two modes of operation. Briefly explain, standalone one-time activation, during operation has been resident in memory, the advantage of quick access signal response, the disadvantage is the loss of a certain amount of system resources, so often applied to real-time response requirements of high professional FTP server . inetd On the contrary, because the process is called only when the FTP connection request is sent externally, and therefore not suitable for connecting a larger number of systems at the same time. In addition, inetd mode does not take up system resources. In addition to the two effects of reaction speed and footprint, vsftpd also provides some additional advanced features such as inetd mode support per_IP (single IP) restrictions, while standalone mode is more conducive to the application of PAM authentication functions.

4. java can not be achieved by deleting - file is modified directly on the way to achieve the replacement update files, but I have not tried. Common delete - whether alternatives should pay attention to 1. The user group and owner of the file and the source file with the same file permissions are the same 2

5. Specifies the version of the source and target maven bytecode

           <maven.compiler.source>8</maven.compiler.source>
           <maven.compiler.target>8</maven.compiler.target>

   And not related to the IDEA set provided in IDEA IDEA is in the run or debug the application will be, but if you use mvn build, then you need to set up in pom.xml
