ipset:保存集合内容到文件

一，保存到文件

1,创建集合:

[root@blog ~]# ipset create myset hash:ip

添加ip:

[root@blog ~]#  ipset add myset 192.168.1.100
[root@blog ~]#  ipset add myset 192.168.1.101
[root@blog ~]#  ipset add myset 192.168.1.102

查看集合信息:

[root@blog ~]# ipset list myset
Name: myset
Type: hash:ip
Revision: 4
Header: family inet hashsize 1024 maxelem 65536
Size in memory: 264
References: 0
Number of entries: 3
Members:
192.168.1.100
192.168.1.102
192.168.1.101

2, 保存到文件:

[root@blog ~]# ipset save myset -f /root/ipset.myset.txt

查看文件内容:

[root@blog ~]# more /root/ipset.myset.txt
create myset hash:ip family inet hashsize 1024 maxelem 65536
add myset 192.168.1.100
add myset 192.168.1.102
add myset 192.168.1.101

二，从文件导入(集合不存在时)

1,删除集合:

[root@blog ~]# ipset destroy myset

查看集合信息:

[root@blog ~]# ipset list myset
ipset v7.1: The set with the given name does not exist

2，集合不存在时导入

[root@blog ~]# ipset restore -f /root/ipset.myset.txt

查看导入后的集合信息:

[root@blog ~]# ipset list myset
Name: myset
Type: hash:ip
Revision: 4
Header: family inet hashsize 1024 maxelem 65536
Size in memory: 264
References: 0
Number of entries: 3
Members:
192.168.1.102
192.168.1.100
192.168.1.101

三，从文件导入（集合存在时）

1,清空集合

清空

[root@blog ~]# ipset flush myset

查看集合信息:

[root@blog ~]# ipset list myset
Name: myset
Type: hash:ip
Revision: 4
Header: family inet hashsize 1024 maxelem 65536
Size in memory: 120
References: 0
Number of entries: 0

2,集合存在时导入：用-exist指明集合存在

[root@blog ~]# ipset restore -f /root/ipset.myset.txt  -exist

查看导入后集合的信息:

[root@blog ~]# ipset list myset
Name: myset
Type: hash:ip
Revision: 4
Header: family inet hashsize 1024 maxelem 65536
Size in memory: 264
