安装软件
[[email protected] ~]# tar -zxf redis-4.0.8.tar.gz
[[email protected] ~]# cd redis-4.0.8/

[[email protected] redis-4.0.8]#
[[email protected] redis-4.0.8]# rpm -q gcc gcc-c++

未安装软件包 gcc-c++
[[email protected] redis-4.0.8]# yum -y install gcc gcc-c++

[[email protected] redis-4.0.8]# make

[[email protected] redis-4.0.8]# make install

初始化配置
[[email protected] redis-4.0.8]# ./utils/install_server.sh //初始化配置
Welcome to the redis service installer
This script will help you easily set up a running redis server

Please select the redis port for this instance: [6379] //端口
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf] //主配文件
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log] //日志文件
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379] //数据库目录
Selected default - /var/lib/redis/6379
Please select the redis executable path [/usr/local/bin/redis-server] //服务程序所在目录

Selected config: #配置摘要信息
Port : 6379
Config file : /etc/redis/6379.conf
Log file : /var/log/redis_6379.log
Data dir : /var/lib/redis/6379
Executable : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli //命令行连接redis服务命令
Is this ok? Then press ENTER to go on or Ctrl-C to abort. //回车完成配置
Copied /tmp/6379.conf => /etc/init.d/redis_6379 //服务启动脚本

启动redis服务（软件安装完成后服务自动运行）
[[email protected] redis-4.0.8]# /etc/init.d/redis_6379 status
Redis is running (5341)
[[email protected] redis-4.0.8]# netstat -utnlp | grep :6379

[[email protected] redis-4.0.8]# ps -C redis-server

连接本机redis服务
[[email protected] redis-4.0.8]# redis-cli

MEMORY MANAGEMENT 内存管理

内存清除策略
565 # volatile-lru -> Evict using approximated LRU among the keys with an expire set. 最近最少使用 （针对设置了过期时间的key）
566 # allkeys-lru -> Evict any key using approximated LRU. 删除最少使用的key

569 # volatile-random -> Remove a random key among the ones with an expire set. 在设置了过期的key里随机移除

570 # allkeys-random -> Remove a random key, any key. 随机移除key

571 # volatile-ttl -> Remove the key with the nearest expire time (minor TTL) 移除最近过期的key

572 # noeviction -> Don‘t evict anything, just return an error on write operations. 不删除 写满时报错

591 # maxmemory-policy noeviction 定义使用的策略

602 # maxmemory-samples 5 选取模板数据的个数 （针对lru 和 ttl 策略）

修改密码后如何调用/etc/init.d/redis_6379 脚本停止服务

给主机53的redis服务设置连接密码 密码是123456

vim /etc/redis/6379.conf
501 requirepass 123456
:wq

/etc/init.d/redis_6379 stop
/etc/init.d/redis_6379 start

连接带认证redis服务
[[email protected] ~]# redis-cli
127.0.0.1:6379> ping
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> ping
PONG
127.0.0.1:6379> quit

[[email protected] ~]# redis-cli -a 123456
127.0.0.1:6379> ping

]# /etc/init.d/redis_6379 stop

[[email protected] ~]# redis-cli -p 6379 -a 123456 shutdown
