systemctl start vsftpd报错

一、环境： centos7
二、过程：
yum install vsftpd 之后显示安装成功
然后systemctl start vsftpd报错

[root@VM_0_2_centos /]# systemctl start vsftpd
Job for vsftpd.service failed because the control process exited with error code. See “systemctl status vsftpd.service” and “journalctl -xe” for details.
按照提示查看 systemctl status vsftpd

[root@VM_0_2_centos /]# systemctl status vsftpd
vsftpd.service - Vsftpd ftp daemon
Loaded: loaded (/usr/lib/systemd/system/vsftpd.service; enabled; vendor preset: disabled)

三、解决： 首先查看端口是否被占用：

[root@VM_0_2_centos /]# lsof -i:21
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
pure-ftpd 16235 root 4u IPv4 1014289 0t0 TCP *:ftp (LISTEN)
pure-ftpd 16235 root 5u IPv6 1014290 0t0 TCP *:ftp (LISTEN)
[root@VM_0_2_centos /]# kill -9 16235
[root@VM_0_2_centos /]# lsof -i:21
再接下来查看配置文件 IPv4 ipv6 不能同时listen. 再启动

[root@VM_0_2_centos /]# systemctl start vsftpd
[root@VM_0_2_centos /]# systemctl status vsftpd
