Custom Asset Discovery Java
方法论
通过find获取java安装路径并执行java -version得到版本。由于find可能获得多行输出，需要考虑如何将多行输出，作为参数以loop方式传递给“-version”命令处理。 或也可使用xargs（但通过time对此测试发现，效率差不多?）
[root@localhost tmp]# time for bar in `timeout 60s find / -not -path "/proc/*" -executable -type f -name java 2>/dev/null`; do $bar -version 2>&1; done

Custom Asset Discovery WebLogic
针对Weglogic自定义安装的检测方法(全盘文件检索60秒timeout),最后列出所有registry.xml路径
原始xml文件样例
version 10.x raw
<component name="WebLogic Server" Version"10.3.4.0" InstallDir="/app/wls11g/bea/wlserver_10.3">
version 12.x raw
<distribution status="installed" name="WebLogic Server for FMW" version="12.1.3.0.0">
脚本
cd /tmp && foo=`timeout 60s find / -not -path "/proc/*" -type f -size -10M -maxdepth 8 -name "registry.xml" 2>/dev/null`; if [ $? -eq 124 ]; then echo "WebLogic not found (Timeout)"; else touch assetemp.log; for bar in $foo; do grep "WebLogic Server" $bar | awk -F '=' '{ print $4 }'| cut -c 2- | sed 's/..$//' >>assetemp.log; done; for bar in $foo; do grep -i 'component name="WebLogic Server" Version' $bar | awk -F '"' '{ print $4 }' >>assetemp.log; done; for ver in `uniq assetemp.log 2>/dev/null`; do echo "WebLogic Version: $ver"; done; echo $foo; fi; rm -f assetemp.log*
输出样例
WebLogic Version: 12.1.3.0.0_fake
WebLogic Version: 12.1.3.0.0
WebLogic Version: 12.2.1.0_fake
WebLogic Version: 10.3.4.0
/root/registry.xml /tmp/registry.xml /tmp/wlstest/registry.xml
Custom Asset Discovery Tomcat
同时对自定义及标准安装Tomcat进行检测(全盘文件检索30秒timeout)
脚本
cd /tmp && foo='for bar in `timeout 30s find / -not -path "/proc/*" -type f -size -10M -maxdepth 8 -name "version.sh" 2>/dev/null | grep tomcat`; do sh $bar; done'; bash -c "$foo" > assetemp.log 2>/dev/null; grep -i "Apache Tomcat" assetemp.log | awk -F "/" '{print $2}' >assetemp.log1; for ver in `sort assetemp.log1 2>/dev/null | uniq`; do echo "Tomcat Version: $ver"; done; rm -f assetemp.log*
输出样例
Tomcat Version: 7.0.76
Tomcat Version: 8.5.39
Custom Asset Discovery Nginx
同时对自定义及标准安装Nginx进行检测(全盘文件检索30秒timeout)
脚本
cd /tmp && foo='for bar in `timeout 30s find / -executable -type f -size -10M -maxdepth 8 -name nginx 2>/dev/null`; do $bar -v 2>&1; done'; bash -c "$foo" >assetemp.log 2>/dev/null; grep -i "nginx version" assetemp.log | awk -F "/" '{print $2}' >assetemp.log1; for ver in `sort assetemp.log1 2>/dev/null | uniq`; do echo "Nginx Version: $ver"; done; rm -f assetemp.log*
输出样例
Nginx Version: 1.15.10
Custom Asset Discovery PHP
同时对自定义及标准安装php进行检测(全盘文件检索30秒timeout)
脚本
cd /tmp && foo='for bar in `timeout 30s find / -executable -type f -size -10M -maxdepth 8 -name php 2>/dev/null`; do $bar -v 2>&1; done'; bash -c "$foo" >assetemp.log 2>/dev/null; grep -i "^PHP" assetemp.log | awk '{print $2}' >assetemp.log1; for ver in `sort assetemp.log1 2>/dev/null | uniq`; do echo "PHP Version: $ver"; done; rm -f assetemp.log*
输出样例
PHP Version: 7.0.33
Custom Asset Discovery Apache
一种比较简单的实现做法，先使用'which -a'找到所有httpd binary
脚本
for bar in `which -a httpd 2>/dev/null`; do $bar -v; done
输出样例
Server version: Apache/2.4.6 (CentOS)
Server built: Nov 5 2018 01:47:09
