+### 问题描述
+
+
+
+> 配置： 2H2G
+>
+> 问题：服务器`BPS/IOPS` 一直处于高负载状态，系统一直在频繁与磁盘交换数据
+>
+> 造成的结果：服务器无法连接，服务器的服务全部失去连接，控制台无法通过普通重启来重启服务器，只能强制重启或关闭
+>
+> 原因分析：运行内存不足导致，由于内存不够系统需要频繁的与磁盘不停的交换数据，占用了大量的IO。

+
+
+
+### 解决办法1
+
+ 升级配置，最简单最简单最无脑。
+
+
+
+### 解决办法2
+
+ 通过拓展swap分区来缓解此问题
+
+
+
+#### 查看系统的swap分区情况
+
+通过`swapon`查看
+
+```bash
+swapon --show
+```
+
+我这里没有任何输出，说明根本不存在swap分区。
+
+
+
+通过free看一下运行内存情况。
+
+```bash
+free -h
+```
+
+这里也可以看到swap全是0
+
+```plaint
+               total        used        free      shared  buff/cache   available
+Mem:           1.6Gi       831Mi       242Mi       1.8Mi       752Mi       844Mi
+Swap:          0		   0		   0
+```
+
+
+
+#### 创建并配置swap
+
+创建并启用一个swap (<span style="background-color: red;">注</span>：以下操作均需要<span style="color: red;">root</span>权限)
+
+```bash
+# 创建 swap 文件
+fallocate -l 4G /swap
+
+# 设置权限
+chmod 600 /swap
+
+# 格式化为swap
+mkswap /swap
+
+# 启用swap
+swapon /swap
+
+# 永久添加到fstab
+echo '/swap none swap defaults 0 0' >> /etc/fstab
+```
+
+
+
+#### 配置 swappiness
+
+检查`swappiness`（取值范围为 0 - 100，数值越大，使用swap的可能性越大）
+
+```bash
+cat /proc/sys/vm/swappiness
+
+# 输出
+0
+```
+
+我这里为0。
+
+
+
+编辑 `/etc/sysctl.conf`将`vm.swappiness` 修改为20
+
+```bash
+vim /etc/sysctl.conf
+
+# 修改 vm.swappiness
+# vm.swappiness = 20
+```
+
+
+
+#### 更新内核参数
+
+更新内核参数，使`swappiness`配置生效
+
+```bash
+sysctl -p
+```
+
+
+
+### 验证结果
+
+再次查看内存和swap情况
+
+ ```bash
+ # 查看swap
+ swapon --show
+ 
+ #输出
+ NAME      TYPE SIZE   USED PRIO
+ /swap     file   4G 547.6M   -2
+ 
+ 
+ # 查看内存
+ free -h
+ 
+ # 输出
+                total        used        free      shared  buff/cache   available
+ Mem:           1.6Gi       746Mi       665Mi       1.8Mi       414Mi       930Mi
+ Swap:          4.0Gi       780Mi       3.2Gi
+ ```
