-How To Disable IPv6 In CentOS 7
-================================================================================
-Recently, one of my friend asked me how to disable IPv6. After searching a bit, I found the following solution. Here is the steps that I followed to disable IPv6 in my CentOS 7 minimal server.
-
-You can do it in two methods.
-
-### Method 1 ###
-
-Edit file **/etc/sysctl.conf**,
-
-    vi /etc/sysctl.conf
-
-Add the following lines:
-
-    net.ipv6.conf.all.disable_ipv6 = 1
-    net.ipv6.conf.default.disable_ipv6 = 1
-
-If you want to disable IPV6 for particular network card, for example enp0s3, add the following entry.
-
-    net.ipv6.conf.enp0s3.disable_ipv6 = 1
-
-Save and exit the file.
-
-Execute the following command to reflect the changes.
-
-    sysctl -p
-
-### Method 2: ###
-
-To IPv6 disable in the running system, enter the following commands one by one:
-
-    echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6
-    echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6
-
-or,
-
-    sysctl -w net.ipv6.conf.all.disable_ipv6=1
-    sysctl -w net.ipv6.conf.default.disable_ipv6=1
-
-That’s it. Now IPv6 has been disabled.
-
-### What If I get issues after disabling IPv6? ###
-
-You may get problems after disabling IPv6.
-
-#### Issue 1: ####
-
-if you get issues with SSH after disabling IPv6, do the following.
-
-Edit **/etc/ssh/sshd_config** file,
-
-vi /etc/ssh/sshd_config
-
-Find the line;
-
-    #AddressFamily any
-
-And. change it to:
-
-    AddressFamily inet
-
-or,
-
-Remove the hash mark **(#)** in front of the line:
-
-    #ListenAddress 0.0.0.0
-
-Then, restart ssh to reflect the changes.
-
-    systemctl restart sshd
-
-#### Issue 2: ####
-
-If you get problems with starting postfix after disabling IPv6, edit **/etc/postfix/main.cf** file;
-
-    vi /etc/postfix/main.cf
-
-and comment out the localhost part of the config and use ipv4 loopback.
-
-    #inet_interfaces = localhost
-    inet_interfaces = 127.0.0.1
-
-That’s it. Cheers!

+如何在CentOS 7中禁止IPv6
+================================================================================
+最近，我的一位朋友问我该如何禁止IPv6。在搜索了一番之后，我找到了下面的方案。下面就是我在CentOS 7迷你版中禁止IPv6的方法。
+
+你可以用两个方法做到这个。
+
+### 方法 1 ###
+
+编辑文件**/etc/sysctl.conf**，
+
+    vi /etc/sysctl.conf
+
+添加下面的行：
+
+    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
+
+保存并退出文件。
+
+执行下面的命令来使设置生效。
+
+    sysctl -p
+
+### 方法 2 ###
+
+要在运行的系统中禁止IPv6，依次输入下面的命令：
+
+    echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6
+    echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6
+
+或者，
+
+    sysctl -w net.ipv6.conf.all.disable_ipv6=1
+    sysctl -w net.ipv6.conf.default.disable_ipv6=1
+
+就是这样。现在IPv6已经禁止了。
+
+### 我在禁止IPv6后遇到问题怎么办 ###
+
+You may get problems after disabling IPv6.
+你可能在禁止IPv6后遇到一些问题
+
+#### 问题1： ####
+
+如果你在禁止IPv6后SSH遇到问题，按照下面的做。
+
+编辑 **/etc/ssh/sshd_config** 文件
+
+vi /etc/ssh/sshd_config
+
+找到下面的行：
+
+    #AddressFamily any
+
+把它改成：
+
+    AddressFamily inet
+
+或者，
+
+在这行的前面去掉注释**(#)**：
+
+    #ListenAddress 0.0.0.0
+
+接着重启ssh来使改变生效。
+
+    systemctl restart sshd
+
+#### 问题2： ####
+
+如果你在禁止Ipv6后启动postfix遇到问题，编辑**/etc/postfix/main.cf**：
+
+    vi /etc/postfix/main.cf
+
+注释掉配置中的localhost部分，并且使用ipv4回环。
+
+    #inet_interfaces = localhost
+    inet_interfaces = 127.0.0.1
+
+就是这样，干杯！
