hj_服务器操作记录
~~~阿里云云服务器(1核2G1M带宽40G云盘.centos8.3 64位 华南1区 2022-12-19到期)
服务器暴露端口设置(3301-3309, 6001-6999, 8001-8999, 9001-9999 10240-10245全部暴露 )
1 创建用户组.添加用户并给管理员权限:
创建组: groupadd hj_manager_group 查看组: cat /etc/group
添加用户: useradd -g hj_manager_group -m hj 查看单用户: id hj 查看所有用户: cat /etc/passwd | grep hj
创建密码: passwd hj 设置root权限: sudo vim /etc/sudoers root ALL=(ALL) ALL <--> hj ALL=(ALL) ALL
事实证明.这个没啥用,还是没有权限~~~还是root用户才好玩.
2 安装docker/podman
查看是否安装过: yum list installed |grep docker
安装: yum -install docker -y ps: 需要root权限,可加sudo~ -y表示不询问安装，直到安装成功，安装完后再次查看安装列表
docker --version Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet ms这是因为与podman冲突.
podman是一个跟docker差不多的容器,语句也基本想通,可以理解为docker升级版,是centos8自带的不需要下载,如果再去下载docker会被放在podman下
所以移除docker安装~ sudo：yum remove docker
安装 podman , yum list installed | grep podman , sudo yum install podman -y , podman --version 显示: podman version 3.3.1
设置别名: alias docker=podman docker images podman images 一样的效果. ps:非一次设置一直有效..
