之前使用阿里雲日志服務，按照文檔安裝了ilogtail。后面不需要了，卻找不到卸載文檔。
仔細查看ilogtail的安裝腳本后，發現里面有卸載方法。
wget http://logtail-release-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/linux64/logtail.sh -O logtail.sh;chmod 755 logtail.sh
./logtail.sh uninstall
正常卸載的反饋結果如下：
logtail.sh version: 1.3.0
Can not get os version from /etc/issue, try lsb_release
./logtail.sh: line 529: lsb_release: command not found
Can not get os version from lsb_release, try check specific files
OS Arch: x86_64
OS Distribution: CentOS

stop logtail success
chkconfig del ilogtaild success
uninstall logtail success
