1. centos安装
1. 环境准备¶
#克隆虚拟机：192.168.178.151
#配置：1C2G
#快照！
2. 安装¶
1.配置宿主机网卡转发¶
## 配置网卡转发,看值是否为1
$ sysctl -a |grep -w net.ipv4.ip_forward
net.ipv4.ip_forward = 1
## 若未配置，需要执行如下
$ cat <<EOF > /etc/sysctl.d/docker.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward=1
EOF
$ sysctl -p /etc/sysctl.d/docker.conf
## 再次查看网卡转发
$ sysctl -a |grep -w net.ipv4.ip_forward
[root@151 ~]# sysctl -a |grep -w net.ipv4.ip_forward
sysctl: reading key "net.ipv6.conf.all.stable_secret "
sysctl: reading key "net.ipv6.conf.default.stable_se cret"
sysctl: reading key "net.ipv6.conf.ens33.stable_secr et"
sysctl: reading key "net.ipv6.conf.lo.stable_secret"
net.ipv4.ip_forward = 0
[root@151 ~]#
[root@151 ~]# cat <<EOF > /etc/sysctl.d/docker.conf
> net.bridge.bridge-nf-call-ip6tables = 1
> net.bridge.bridge-nf-call-iptables = 1
> net.ipv4.ip_forward=1
> EOF
[root@151 ~]#
[root@151 ~]# sysctl -p /etc/sysctl.d/docker.conf
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No such file or directory
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory
net.ipv4.ip_forward = 1
[root@151 ~]#
[root@151 ~]# sysctl -a |grep -w net.ipv4.ip_forward
net.ipv4.ip_forward = 1
sysctl: reading key "net.ipv6.conf.all.stable_secret"
sysctl: reading key "net.ipv6.conf.default.stable_secret"
sysctl: reading key "net.ipv6.conf.ens33.stable_secret"
sysctl: reading key "net.ipv6.conf.lo.stable_secret"
[root@151 ~]#
2.Yum安装配置docker¶
## 下载阿里源repo文件
$ curl -o /etc/yum.repos.d/Centos-7.repo http://mirrors.aliyun.com/repo/Centos-7.repo
$ curl -o /etc/yum.repos.d/docker-ce.repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
$ yum clean all && yum makecache
## yum安装
$ yum install -y docker-ce
## 查看源中可用版本
$ yum list docker-ce --showduplicates | sort -r
## 安装指定版本
##yum install -y docker-ce-18.09.9
## 配置源加速
## https://cr.console.aliyun.com/cn-hangzhou/instances/mirrors
mkdir -p /etc/docker
vi /etc/docker/daemon.json
{
"registry-mirrors" : [
"https://8xpk5wnt.mirror.aliyuncs.com",
"https://dockerhub.azk8s.cn",
"https://registry.docker-cn.com",
"https://ot2k4d59.mirror.aliyuncs.com/"
]
}
## 设置开机自启
systemctl enable docker
systemctl daemon-reload
## 启动docker
systemctl start docker
## 查看docker信息
docker info
## docker-client
which docker
## docker daemon
ps aux |grep docker
