前些天安装蓝鲸的测试环境频繁出现You have new mail in /var/spool/mail/root，查看发现是/usr/local/gse/agent/bin/gsectl: line 19: ip: command not found，查了下报错频率基本上是每分钟报错一次。
[root@rbtnode1 install]#
You have new mail in /var/spool/mail/root
[root@rbtnode1 install]#
[root@rbtnode1 install]# tail -20f /var/spool/mail/root

/usr/local/gse/agent/bin/gsectl: line 19: ip: command not found
^C看下目前为止的报错次数：
[root@rbtnode1 install]# grep "line 19: ip: command not found" /var/spool/mail/root |wc -l
15748
[root@rbtnode1 install]#
You have new mail in /var/spool/mail/root
[root@rbtnode1 install]# grep "line 19: ip: command not found" /var/spool/mail/root |wc -l
15750查看/usr/local/gse/agent/bin/gsectl文件，vi定位到19行：
17 get_lan_ip () {
18 #
19 ip addr | \
20 awk -F'[ /]+' '/inet/{
21 split($3, N, ".")
22 if ($3 ~ /^192.168/) {
23 print $3
24 }
25 if (($3 ~ /^172/) && (N[2] >= 16)) {
26 print $3
27 }
28 if ($3 ~ /^10\./) {
29 print $3
30 }
31 }'
32 return $?
33 }
34 export LAN_IP=$(get_lan_ip | head -1)使用which ip 查看系统ip命令的路径：
[root@rbtnode1 install]# which ip
/usr/sbin/ip尝试修改第19行，ip命令的调用改为绝对路径：/usr/sbin/ip
19 /usr/sbin/ip addr | \再次查看报错次数和最近的报错时间：
[root@rbtnode1 install]# grep "line 19: ip: command not found" /var/spool/mail/root |wc -l
15755
[root@rbtnode1 install]# tail -20f /var/spool/mail/root

/usr/local/gse/agent/bin/gsectl: line 19: ip: command not found后续观察没再发现这个报错计数增长，也没有16:58:03之后的报错信息，说明改动有效。
