+## 一、修改root密码
+```
+passwd root
+```
+
+## 二、添加可sudo的管理员用户并设置密码
+Redhat/CentOS系：
+```
+useradd -m -g wheel -s /bin/bash "username" && passwd "username"
+```
+Debian/ubuntu系：
+```
+useradd -m -g sudo -s /bin/bash "username" && passwd "username"
+```  
+
+## 三、清理无用账号（如有）
+
+- 进入指定账户home目录，备份文件至/tmp下
+```
+cd /home/"username"
+mv *  /tmp
+```
+- 删除账号及目录
+```
+userdel -rf "username"
+```
+
+
+## 四、修改SSH安全配置
+
+编辑SSH配置文件:
+```
+vi /etc/ssh/sshd.config
+```
+将下列语句加入文件最后:  
+```
+PermitRootLogin no
+Ciphers aes256-ctr,aes192-ctr,aes128-ctr
+MACs hmac-sha2-512,hmac-sha2-256
+```
+
+添加完成后重启ssh服务：
+```
+systemctl restart sshd
+```
+
+## 五、添加软件源，更新所有应用程序
+阿里云服务器参考[深圳国家基因库开源镜像站](https://gitlab.genomics.cn/tianjing/faq/-/wikis/%E5%9B%BD%E5%AE%B6%E5%9F%BA%E5%9B%A0%E5%BA%93%E5%BC%80%E6%BA%90%E9%95%9C%E5%83%8F%E7%AB%99)  
+集团横岗&盐田虚拟化平台参考[华大集团开源镜像站](https://gitlab.genomics.cn/yangjiewei/platformops-faq/-/wikis/%E5%8D%8E%E5%A4%A7%E9%9B%86%E5%9B%A2%E5%BC%80%E6%BA%90%E9%95%9C%E5%83%8F%E7%AB%99)  
+其他地区参考华为云或阿里云软件源进行互联网更新。  
+
+
+Redhat/CentOS系软件更新：
+```
+sudo yum update -y
+```
+Debian/ubuntu系软件更新：
+```
+sudo apt update
+sudo apt upgrade
+```
+## 六、检查是否安装HIDS，如未安装先安装HIDS客户端
+
+参考[HIDS安装指南](https://gitlab.genomics.cn/moshengan/issmkd/-/wikis/%E4%B8%BB%E6%9C%BA%E5%85%A5%E4%BE%B5%E6%A3%80%E6%B5%8B%E7%B3%BB%E7%BB%9F(HIDS)Agent%E5%AE%89%E8%A3%85%E6%8C%87%E5%8D%97)
+
+## 七、配置时区和时钟同步
+
+设置时区：
+```
+timedatectl set-timezone Asia/Shanghai
+```
+
+<details><summary>RHEL9时钟同步服务：</summary>
+
+```
+#编辑配置文件，加上ntp server
+sudo vim /etc/chrony.conf
+
+#时钟源
+server ntp.genomics.cn
+server ntp.ntsc.ac.cn
+
+#重启服务
+systemctl restart chronyd
+
+#查看同步状态
+chronyc sources
+```

+
+
+</details>
+
+<details><summary>Debian/ubuntu安装ntp服务：</summary>
+
+```
+sudo apt install ntpsec -y
+```
+编辑ntp服务配置文件：
+```
+vim /etc/ntpsec/ntp.conf
+```
+#将原来的pool和server全部注释，然后增加内网NTP Server和中科院备用NTP Server  
+![image](uploads/e455867333b06263987263585df7536d/image.png)  
+
+重启NTP服务:
+```
+systemctl restart ntpsec
+```
+查看服务状态：
+```
+systemctl status ntpsec
+```
+```
+#查看时钟同步状态
+ntpq -p
+```
