# CentOS7 禁用 ipv6
|
||
## 方法1
|
||
- 编辑 /etc/sysctl.conf，增加如下内容
|
||
```
|
||
net.ipv6.conf.all.disable_ipv6 =1
|
||
net.ipv6.conf.default.disable_ipv6 =1
|
||
```
|
||
- 如果你想要为特定的网卡禁止IPv6，比如，对于enp0s3，添加下面的行
|
||
```
|
||
net.ipv6.conf.enp0s3.disable_ipv6 =1
|
||
```
|
||
- 生效
|
||
```bash
|
||
sysctl -p
|
||
```
|
||
|
||
## 方法2
|
||
- 执行下面命令
|
||
```bash
|
||
echo 1>/proc/sys/net/ipv6/conf/all/disable_ipv6
|
||
echo 1>/proc/sys/net/ipv6/conf/default/disable_ipv6
|
||
```
