现在使用宝塔面板的人越来越多了，各种BUG和使用经验也是积累了很多，今天笔记君记录一条使用宝塔面板时的错误提示的解决办法。使用CentOS 6安装宝塔面板的过程中出现错误提示如下：
- iptables: Invalid argument. Run `dmesg' for more information.
- iptables: Saving firewall rules to /etc/sysconfig/iptables: [ OK ]
- iptables: Setting chains to policy ACCEPT: security raw nat[ OK ]filter
- iptables: Flushing firewall rules: [ OK ]
- iptables: Unloading modules: [ OK ]
- iptables: Applying firewall rules: [ OK ]
- iptables: Loading additional modules: ip_conntrack_netbios_ns ip_conntrack_ftp ip_nat_ftp [FAILED]
其实问题出在/etc/sysconfig/iptables-config，打开它：
- vi /etc/sysconfig/iptables-config
注释掉：IPTABLES_MODULES="ip_conntrack_netbios_ns ip_conntrack_ftp ip_nat_ftp"：
- # Load additional iptables modules (nat helpers)
- # Default: -none-
- # Space separated list of nat helpers (e.g. 'ip_nat_ftp ip_nat_irc'), which
- # are loaded after the firewall rules are applied. Options for the helpers are
- # stored in /etc/modprobe.conf.
- #IPTABLES_MODULES="ip_conntrack_netbios_ns ip_conntrack_ftp ip_nat_ftp" //就是这一行，注释掉
- # Unload modules on restart and stop
- # Value: yes|no, default: yes
- # This option has to be 'yes' to get to a sane state for a firewall
- # restart or stop. Only set to 'no' if there are problems unloading netfilter
- # modules.
- IPTABLES_MODULES_UNLOAD="yes"
- # Save current firewall rules on stop.
- # Value: yes|no, default: no
- # Saves all firewall rules to /etc/sysconfig/iptables if firewall gets stopped
- # (e.g. on system shutdown).
- IPTABLES_SAVE_ON_STOP="no"

好像是配置netbios穿越NAT用的，一般用不到的。
ip_conntrack_netbios_ns 这个模块在make menuconfig 中是IP_NF_NETBIOS_NS。
- [root@li1583-161 ~]# /etc/init.d/iptables restart
- iptables: Setting chains to policy ACCEPT: security raw nat[ OK ]filter
- iptables: Flushing firewall rules: [ OK ]
- iptables: Unloading modules: [ OK ]
- iptables: Applying firewall rules: [ OK ]
是不是改定了呢？^-^
还有一种解决办法，就是直接使用使用CentOS 7系统安装宝塔，就不会出现上述问题，记录于此，以备所需。
