相关文章: centos 7.8.2003版本docker安装失败问题记录

出现的原因是因为我修改了/etc/systemd/system.conf, 随后在重启后发现 Docker 无法启动, 查看对应日志:

[root@jh-java ~]# systemctl start docker
Job for docker.service failed because the control process exited with error code. See “systemctl status docker.service” and “journalctl -xe” for details.
[root@jh-java ~]# systemctl status docker
● docker.service - Docker Application Container Engine

在经过查询后得知是因为 open file 限制的问题, 需要修改/lib/systemd/system/<服务名>.serviceLimitNOFILE=unlimitedLimitNOFILE=<对应上限>即可解决
