1. OS installation
2. Proxy Setting
在一般公司的環境下Client端都需要設定Proxy才可以對外連線
假設Proxy的IP:192.168.1.10 , port:8080
編輯 .bash_profile (root目錄下) ,新增以下(紅字)：
http_proxy=192.168.1.10:8080
ftp_proxy=192.168.1.10:8080
export http_proxy
export ftp_proxy
執行
[root@Server ~]# source .bash_profile
看看是否設定成功
[root@Server ~]# echo $http_proxy
192.168.1.10:8080
如果要讓這台主機的所有 http / https 都走 proxy 就設定在 /etc/profile
|
|
$ echo "export http_proxy=http://proxy.example.com" >> /etc/profile
$ echo "export https_proxy=https://proxy.example.com" >> /etc/profile
|
2.1 For Yum proxy setting
/etc/yum.conf
add line proxy=http://192.160.1.1:8080
$ vim /etc/apt/apt.conf
Acquire::http::Proxy "http://proxy.example.com";
2.2 Docker Hub Proxy setting [
Refer]
mkdir /etc/systemd/system/docker.service.d
vim /etc/systemd/system/docker.service.d/http-proxy.conf
[Service]
Environment="HTTP_PROXY=http://10.1.107.222:8080"
systemctl daemon-reload
systemctl show --property Environment docker
設定永久變數
永久變數可以寫在登入後會讀取的 ~/.bash_profile , ~/.bashrc
|
|
$ echo "export http_proxy=http://proxy.example.com" >> ~/.bashrc
$ echo "export https_proxy=https://proxy.example.com" >> ~/.bashrc
|
如果要讓這台主機的所有 http / https 都走 proxy 就設定在 /etc/profile
|
|
$ echo "export http_proxy=http://proxy.example.com" >> /etc/profile
$ echo "export https_proxy=https://proxy.example.com" >> /etc/profile
|
|
|
# YUM setting
$ vim /etc/yum.conf
proxy=http://proxy.example.com
# APT setting
$ vim /etc/apt/apt.conf
Acquire::http::Proxy "http://proxy.example.com";
|
3. Yum install OpenSSH server
$ sudo yum install openssh openssh-server
4. Edit /etc/ssh/sshd_config
Port 22 -> xxx
PermitRootLogin no
Protocol 2
sudo systemctl restart sshd.service
sudo systemctl enable sshd.service
sudo systemctl status sshd.service
5. Config Firewall
