RStudio Server: Unable to connect to service

centos 8 安装好Rstudio server后，登陆 IP:8787 网址显示：

命令行状态报错显示如下：

[root@localhost yangl]# rstudio-server status

这个是因为目前Rstudio server 与SELinux不兼容导致，但SELinux 在 RedHat/CentOS/Fedora 及其衍生系统中默认开启导致，解决办法：
默认是开启状态：

[root@localhost yangl]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /sys/fs/selinux
SELinux root directory:         /etc/selinux
Loaded policy name:             targeted
Current mode:                   enforcing
Mode from config file:          enforcing
Policy MLS status:              enabled
Policy deny_unknown status:     allowed
Memory protection checking:     actual (secure)
Max kernel policy version:      32

关闭SELinux:

[root@localhost yangl]# vi /etc/sysconfig/selinux
将SELINUX=enforcing 改为 SELINUX=disabled

然后重启电脑解决问题！
