1、命令卸载如果命令还卸载不赶紧，就在FreeIPA界面删除
ipa-server-install -U --uninstall #服务端卸
ipa-client-install -U --uninstall #客户端卸载#删除残留文件，避免二次安装失败
cd /var/lib/ipa/
rm -f ca*
rm -f *.txt
rm -f sysrestore/*
cd /var/lib/dirsrv/
rm -rf scripts*
cd /var/run/dirsrv/
rm -rf slapd*
cd /etc/ipa
rm -f ca.crt
cd /var/log/dirsrv
rm -rf slapd*
rm -rf /var/lib/pki* /var/log/pki* /etc/init.d/pki*
rm -rf /usr/share/pki /usr/share/tomcat5/var/lib/tomcat5/
#卸载软件包
yum erase -y `rpmquery -a | grep freeipa``rpmquery -a | grep ^pki-` `rpmquery -a | grep tomcat6` `rpmquery -a | grep httpd` 389-ds-base bind
