甲骨文云主机ubuntu系统设置

首先需要搞定root用密码登录

sudo -i
echo root:admin |chpasswd root
sed -i 's/^#\?PermitRootLogin.*/PermitRootLogin yes/g' /etc/ssh/sshd_config;
sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication yes/g' /etc/ssh/sshd_config;
service sshd restart

关闭防火墙

iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -F
apt-get purge netfilter-persistent

申请SSL证书

apt update -y
apt install -y curl
apt install -y socat
curl https://get.acme.sh | sh
~/.acme.sh/acme.sh --register-account -m XXXX@XXX.com
~/.acme.sh/acme.sh --issue -d xxx.xxx.xxx --standalone
~/.acme.sh/acme.sh --installcert -d xxx.xxx.xxx --key-file /root/private.key --fullchain-file /root/cert.crt
