首先任意运行一条iptables防火墙规则配置命令如开通80端口: # g) J& S _# x0 n3 D$ u# n; j
iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
" Z1 v7 Y/ y: U. q# H: ^
然后对iptables服务进行保存: ) H5 V. `1 r5 T4 U- @) r3 Y
service iptables save 0 p; P7 C8 V2 o& P3 E5 W
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.
; ^* m) O* }4 d w
解决方法:$ l5 `4 F- o+ E
systemctl stop firewalld 关闭防火墙 ; S$ U5 H1 b0 |7 I/ O
yum install iptables-services 安装或更新服务
( N3 w8 Y. ^3 r再使用systemctl enable iptables 启动iptables
) J7 R- D# v% \+ `" X
最后 systemctl start iptables 打开iptables % W+ z9 U, `" B; t
再执行service iptables save
" O9 K, N# ~: V" _& B, z. X7 I9 x1 R
然后重启iptables服务:
# w" s1 A; G6 N& ]
service iptables restart
1 p2 f9 M# B( o, n N* X
执行完毕之后/etc/syscofig/iptables文件就有了 / A$ _! |* @- H) q( Q' H: H0 Y
