如果你运行的是大型 Linux 环境,那么你可能已经将 Red Hat 与 Satellite 集成了。如果是的话,你不必担心补丁合规性报告,因为有一种方法可以从 Satellite 服务器导出它。
2019-11-16 10:14:32 +08:00
但是,如果你运行的是没有 Satellite 集成的小型 Red Hat 环境,或者它是 CentOS 系统,那么此脚本将帮助你创建该报告。
2019-11-16 10:14:32 +08:00
补丁合规性报告通常每月创建一次或三个月一次,具体取决于公司的需求。根据你的需要添加 cronjob 来自动执行此功能。
2019-11-14 08:51:30 +08:00
此 [bash 脚本][1] 通常适合于少于 50 个系统运行,但没有限制。

保持系统最新是 Linux 管理员的一项重要任务,它使你的计算机非常稳定和安全。

此教程中包含四个 [shell 脚本][5],请选择适合你的脚本。
2019-11-14 08:51:30 +08:00
### 方法 1为 CentOS / RHEL 系统上的安全修补生成补丁合规性报告的 Bash 脚本
2019-11-14 08:51:30 +08:00
此脚本只会生成安全修补合规性报告。它会通过纯文本发送邮件。
```
# vi /opt/scripts/small-scripts/sec-errata.sh
#!/bin/sh
/tmp/sec-up.txt
SUBJECT="Patching Reports on "date""
MESSAGE="/tmp/sec-up.txt"
TO="[email protected]"
echo "+---------------+-----------------------------+" >> $MESSAGE
echo "| Server_Name | Security Errata |" >> $MESSAGE
echo "+---------------+-----------------------------+" >> $MESSAGE
for server in `more /opt/scripts/server.txt`
do
sec=`ssh $server yum updateinfo summary | grep 'Security' | grep -v 'Important|Moderate' | tail -1 | awk '{print $1}'`
echo "$server $sec" >> $MESSAGE
done
echo "+---------------------------------------------+" >> $MESSAGE
mail -s "$SUBJECT" "$TO" < $MESSAGE
```
2019-11-14 08:51:30 +08:00
添加完上面的脚本后运行它。
```
# sh /opt/scripts/small-scripts/sec-errata.sh
```
2019-11-14 08:51:30 +08:00
你会看到下面的输出。
```
# cat /tmp/sec-up.txt
+---------------+-------------------+
| Server_Name | Security Errata |
+---------------+-------------------+
server1
server2
server3 21
server4
+-----------------------------------+
```
2019-11-16 10:14:32 +08:00
添加下面的 cronjob 来每个月得到一份补丁合规性报告。
```
# crontab -e
@monthly /bin/bash /opt/scripts/system-uptime-script-1.sh
```
2019-11-14 08:51:30 +08:00
### 方法 1a为 CentOS / RHEL 系统上的安全修补生成补丁合规性报告的 Bash 脚本
2019-11-14 08:51:30 +08:00
脚本会为你生成安全修补合规性报告。它会通过 CSV 文件发送邮件。
```
# vi /opt/scripts/small-scripts/sec-errata-1.sh
#!/bin/sh
echo "Server Name, Security Errata" > /tmp/sec-up.csv
for server in `more /opt/scripts/server.txt`
do
sec=`ssh $server yum updateinfo summary | grep 'Security' | grep -v 'Important|Moderate' | tail -1 | awk '{print $1}'`
echo "$server, $sec" >> /tmp/sec-up.csv
done
echo "Patching Report for `date +"%B %Y"`" | mailx -s "Patching Report on `date`" -a /tmp/sec-up.csv [email protected]
rm /tmp/sec-up.csv
```
2019-11-14 08:51:30 +08:00
添加完上面的脚本后运行它。
```
# sh /opt/scripts/small-scripts/sec-errata-1.sh
```
2019-11-14 08:51:30 +08:00
你会看到下面的输出。
![][6]
2019-11-14 08:51:30 +08:00
### 方法 2为 CentOS / RHEL 系统上的安全修补、bugfix、增强生成补丁合规性报告的 Bash 脚本
2019-11-14 08:51:30 +08:00
脚本会为你生成安全修补、bugfix、增强的补丁合规性报告。它会通过纯文本发送邮件。
```
# vi /opt/scripts/small-scripts/sec-errata-bugfix-enhancement.sh
#!/bin/sh
/tmp/sec-up.txt
SUBJECT="Patching Reports on "`date`""
MESSAGE="/tmp/sec-up.txt"
TO="[email protected]"
echo "+---------------+-------------------+--------+---------------------+" >> $MESSAGE
echo "| Server_Name | Security Errata | Bugfix | Enhancement |" >> $MESSAGE
echo "+---------------+-------------------+--------+---------------------+" >> $MESSAGE
for server in `more /opt/scripts/server.txt`
do
sec=`ssh $server yum updateinfo summary | grep 'Security' | grep -v 'Important|Moderate' | tail -1 | awk '{print $1}'`
bug=`ssh $server yum updateinfo summary | grep 'Bugfix' | tail -1 | awk '{print $1}'`
enhance=`ssh $server yum updateinfo summary | grep 'Enhancement' | tail -1 | awk '{print $1}'`
echo "$server $sec $bug $enhance" >> $MESSAGE
done
echo "+------------------------------------------------------------------+" >> $MESSAGE
mail -s "$SUBJECT" "$TO" < $MESSAGE
```
2019-11-14 08:51:30 +08:00
添加完上面的脚本后运行它。
```
# sh /opt/scripts/small-scripts/sec-errata-bugfix-enhancement.sh
```
2019-11-14 08:51:30 +08:00
你会看到下面的输出。
```
# cat /tmp/sec-up.txt
+---------------+-------------------+--------+---------------------+
| Server_Name | Security Errata | Bugfix | Enhancement |
+---------------+-------------------+--------+---------------------+
server01 16
server02 5 16
server03 21 266 20
server04 16
+------------------------------------------------------------------+
```
2019-11-14 08:51:30 +08:00
添加下面的 cronjob 来每三个月得到补丁合规性报告。该脚本计划在一月、四月、七月、十月的 1 号运行。
```
# crontab -e
0 0 01 */3 * /bin/bash /opt/scripts/system-uptime-script-1.sh
```
