docker 運行報錯：/bin/bash: error while loading shared libraries: libtinfo.so.6: cannot open shared object file: Permission denied

轉自：https://www.cnblogs.com/wangzy-Zj/p/12797536.html

現象：啟動docker容器時，啟動不成功。顯示沒有權限

 

報錯如下：

 

 原因：共享庫沒有權限導致，如果是普通用戶，則嘗試切換到root用戶嘗試，如果是root用戶還是提示這個錯誤，就要檢查防火牆和SElinux

 

[root@localhost opt]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)
[root@localhost opt]# getenforce 
Enforcing

由此可知是SEliunx沒有關閉導致容器啟動失敗，臨時開發SELinux

[root@localhost opt]# setenforce 0
[root@localhost opt]# docker run -it centos /bin/bash
[root@eff214edebe5 /]#     #表明成功進入到容器中

啟動成功。建議永久關閉

[root@localhost ~]# vi /etc/selinux/config
....
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled    #改成disabled
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
....

修改后需重啟服務器。
