首先任意运行一条iptables防火墙规则配置命令如开通80端口: 9 w' s: O' ?/ h v' i4 d4 H7 V+ E$ K
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
$ c$ G u; F* @$ d( u
然后对iptables服务进行保存:
. g- o- V5 r! e+ i" Z/ X
service iptables save
# E( X( o5 q/ G+ i# y) T4 G
如果失败报出:The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl. 6 v6 j! [; e4 {: ^& i; t2 o$ J
解决方法:# t- q5 L/ Z* U; J) G
systemctl stop firewalld 关闭防火墙
N1 g) R1 f% ?yum install iptables-services 安装或更新服务
7 R: j T2 d- w2 c1 i
再使用systemctl enable iptables 启动iptables ; s: [" L4 w- P0 @" [1 h
最后 systemctl start iptables 打开iptables
8 b1 O0 E8 [+ l$ o' [
再执行service iptables save
' P6 G; \4 ]4 O: e, F0 {9 v' S
然后重启iptables服务:
: O+ ^+ [% c; i! v; e; b
service iptables restart
& v4 S* X' E0 ^: ^; [1 @' P& N3 u
执行完毕之后/etc/syscofig/iptables文件就有了 0 t+ O2 n6 J! T4 t6 B/ V
