删除apache的签名脚本。
#!/usr/bash
#modify Apache conf to add ServerSignature Off and ServerTokens Prod to remove Apache server signature
APACHE_CFG_FILE=/etc/httpd/conf/httpd.conf
FindServerSignatureOff=`grep "^ServerSignature Off$" $APACHE_CFG_FILE`
if [[ -z $FindServerSignatureOff ]]; then
sed -e ‘s/^ServerSignature/#&/‘ -e ‘$aServerSignature Off‘ -i $APACHE_CFG_FILE
requiresApacheRestart=1
fi
FindServerTokensProd=`grep "^ServerTokens Prod$" $APACHE_CFG_FILE`
if [[ -z $FindServerTokensProd ]]; then
sed -e ‘s/^ServerTokens/#&/‘ -e ‘$aServerTokens Prod‘ -i $APACHE_CFG_FILE
requiresApacheRestart=1
fi
#Restart apache to pick up changes
if [ $requiresApacheRestart -eq 1 ]; then
log "INFO: modifyApacheSecurityConfig() - Restarting apache to activate new values"
service httpd restart
fi
注意几点:
1. 判断在文件中是否存在某个字符串用-z/-n, 其中 -z表示grep到的字符串为空,也即不存在,-n表示grep到的字符串不为空,也即存在。判断的时候要用[[ ]], 不是[ ]
2. sed 可以用-e (即表达多),来操作多个表达式,-i表示in-place
3. 最后要重启了httpd deamon service才能生效。
