centos7.5上面安装docker-ce
目前大家用的最多的还是docker 的社区版本,这里简单的意思就是用yum进行安装部署,主要是前期的docker环境配置
- 安装的主要步骤
关闭selinux
[root@localhost ~]# vi /etc/selinux/config #修改selinux配置文件,修改完这个配置文件后需要重启服务器生效的,但是如果说不想重启服务器的话,用下面的那个命令
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@localhost ~]# setenforce 0 #不重启服务器,临时关闭selinux关闭防火墙
[root@localhost ~]# systemctl stop firewalld #关闭防火墙
[root@localhost ~]# systemctl disable firewalld #关闭防火墙开机自启
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.配置阿里源和加速项
[root@localhost ~]# yum -y install wget #安装wget服务,下载repo文件,配置阿里yum源

出现上面的相关信息,代表着我们的docker已经部署完了,是不是很简单哈
