安装宝塔面板提示:ip_conntrack_netbios_ns ip_conntrack_ftp ip_nat_ftp [FAILED]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.

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"

[root@Labs ~]# service 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 ]

直接使用使用CentOS 7.x系统安装宝塔，就不会出现上述问题。
