操作系统:Linux
Linux发行版:Centos7
或者使用命令:
Linux发行版:Centos7
安装
下载地址,点这里Redis4.0.0.tar.gz或者使用命令:
wget http://download.redis.io/releases/redis-4.0.0.tar.gz[/code]
然后执行make编译源码:
tar xzf redis-4.0.0.tar.gz
cd redis-4.0.0
make
src/redis-server
测试效果:
src/redis-cli ping
PONG
src/redis-cli
redis> set foo bar
OK
redis> get foo
“bar”
make命令执行完成后,会在src目录下生成6个可执行文件,分别是redis-server、redis-cli、redis-benchmark、redis-check-aof、redis-check-dump、redis-sentinel
redis-server is the Redis Server itself.(Redis服务器本身)
redis-sentinel is the Redis Sentinel executable (monitoring and failover).(Redis集群的管理工具)
redis-cli is the command line interface utility to talk with Redis.(与Redis进行交互的命令行客户端)
redis-benchmark is used to check Redis performances.(Redis性能测试工具)
redis-check-aof and redis-check-dump are useful in the rare event of corrupted data files.(AOF文件修复工具和RDB文件检查工具)使用如下命令,把redis-server和redis-cli拷贝到合适的位置(/usr/local/bin/):
sudo cp src/redis-server /usr/local/bin/ sudo cp src/redis-cli /usr/local/bin/
或者,使用 sudo make install可以把6个文件都拷贝过去;
这样的话,只要/usr/local/bin/在PATH环境变量里,[root@VM_199_48_centos ~]# echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
我们就可以直接使用redis-server和redis-cli而不需要指定全路径了。比如:[root@localhost ~]# redis-server 12408:C 16 Jul 21:30:29.657 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 12408:C 16 Jul 21:30:29.657 # Redis version=4.0.0, bits=64, commit=00000000, mod ified=0, pid=12408, just started 12408:C 16 Jul 21:30:29.657 # Warning: no config file specified, using the defau lt config.

关闭redis服务使用如下命令可以关闭redis服务
$ redis-cli shutdown
配置初始化脚本,以服务方式启动redis
新建两个文件夹,分别用来存储redis配置文件和持久化文件sudo mkdir /var/redis/6379
拷贝redis-4.0.0下的utils目录下的初始化脚本到/etc/init.d目录,并重命名文件为:redis_+端口号sudo cp utils/redis_init_script /etc/init.d/redis_6379
确保redis_6379文件内的REDISPORT变量是你使用的端口号
新建文件夹/etc/redis/ ,并拷贝redis-4.0.0下的 redis.conf 文件到到改目录下,使用端口号作为文件名sudo mkdir /etc/redis sudo cp redis.conf /etc/redis/6379.conf sudo mkdir -p /var/redis/6379 创建用来存储redis持久化文件的目录(6379为端口号)
编辑6379.conf文件,修改如下几个参数:Set daemonize to yes (by default it is set to no).(设置daemonize 为yes,默认为no) Set the pidfile to /var/run/redis_6379.pid (modify the port if needed).(如果端口号不是6379,则需要修改) Change the port accordingly. In our example it is not needed as the default port is already 6379.(如果端口号不是6379,则需要修改) Set your preferred loglevel.(可以设置日志等级,注释上有说明) Set the logfile to /var/log/redis/redis_6379.log(设置日志文件路径) Set the dir to /var/redis/6379 (very important step!)(设置工作目录为 /var/redis/6379)
这时候就可以使用如下两条命令(任选其一)来启动redis,并测试[root@localhost /]# service redis_6379 start Starting Redis server... [root@localhost /]# redis-cli 127.0.0.1:6379> ping PONG 127.0.0.1:6379> [root@localhost /]# /etc/init.d/redis_6379 start Starting Redis server... 设置开机自动启动
编辑/etc/init.d/redis_6379文件,在#!/bin/bash 之后添加如下两行。
# chkconfig: 2345 10 90
# description: redis_6379 service manage…
其中2345是默认启动级别,级别有0-6共7个级别。
等级0表示:表示关机
等级1表示:单用户模式
等级2表示:无网络连接的多用户命令行模式
等级3表示:有网络连接的多用户命令行模式
等级4表示:不可用
等级5表示:带图形界面的多用户模式
等级6表示:重新启动
10是启动优先级,90是停止优先级,优先级范围是0-100,数字越大,优先级越低
将redis_6379放入linux启动管理体系中chkconfig --add redis_6379
查看redis_6379服务在各运行级状态chkconfig --list redis_6379
重启服务器测试效果:reboot
重启完成后,直接使用redis-cli连接redis,效果如下:Using username "root". Last login: Sun Jul 16 21:30:16 2017 from 192.168.10.1 [root@localhost ~]# redis-cli 127.0.0.1:6379>
配置成功,完!
