redis 高级应用— 安全性

安装完成redis 后接触一下高级应用：

/home/grid/redis*/ redis.conf 下

Redis高级应用

1. 安全性

2. 主从复制

3. 事物处理

4. 持久化机制

5. 发布订阅消息（用这个东西可以做一个消息系统）

6. 虚拟内存的使用

看一下第一 安全性
vi redis.conf 找到 # requirepass foobared 在下面一行添加 requirepass 123456（密码）
因为打开的内容太多 所以用vi 查找命令 输入 /requirepass foobared可以直接到改行
添加一行
requirepass 123456

退出出来
[root@h1 redis-2.8.12]# cd src

[root@h1 src]# redis-cli shutdown

[12410] 15 Dec 14:39:47.268 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1'
for this to take effect.
