Linux下Redis 6.2.6安装和部署详细图文步骤

Redis（Remote Dictionary Server），即远程字典服务，是一个开源的使用ANSI C语言编写、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库，并提供多种语言的API。而Redis 6.0引入了SSL、新的 RESP3 协议、ACL、客户端缓存、无盘副本、I/O 线程、更快的RDB加载、新模块API和更多改进。

1、下载redis6.2.6安装包

访问https://redis.io/download地址到官网进行下载，本文已最新版redis6.2.6版本演示安装和配置。

直接点击上图红框中下载按钮，然后通过远程工具上传至服务器即可，或者通过wget命令下载。

[root@Java-JingXuan home]# wget https://download.redis.io/releases/redis-6.2.6.tar.gz

2、解压压缩文件

解压redis-6.2.6.tar.gz文件，执行tar -xvf redis-6.2.6.tar.gz命令。

[root@Java-JingXuan home]# tar -xvf redis-6.2.6.tar.gz
...
redis-6.2.6/utils/srandmember/README.md
redis-6.2.6/utils/srandmember/showdist.rb
redis-6.2.6/utils/srandmember/showfreq.rb
redis-6.2.6/utils/systemd-redis_multiple_servers@.service
redis-6.2.6/utils/systemd-redis_server.service
redis-6.2.6/utils/tracking_collisions.c
redis-6.2.6/utils/whatisdoing.sh

3、重命名和移动文件

这里东哥将安装目录移动到/usr/local/目录下，并将redis-6.2.6重名为redis目录，使用mv /home/redis-6.2.6 /usr/local/redis命令，因此有如下操作。

[root@Java-JingXuan home]# mv /home/redis-6.2.6 /usr/local/redis
[root@Java-JingXuan home]# cd /usr/local/redis
[root@Java-JingXuan redis]# ll
total 240

4、redis编译安装

1）redis编译，执行make命令。

[root@Java-JingXuan redis]# make
cd src && make all
make[1]: Entering directory `/usr/local/redis/src'
    CC Makefile.dep
...
    LINK redis-benchmark
    INSTALL redis-check-rdb
    INSTALL redis-check-aof

Hint: It's a good idea to run 'make test' ;)

make[1]: Leaving directory `/usr/local/redis/src'

2）redis安装执行make install命令。

[root@Java-JingXuan redis]# make install
cd src && make install
make[1]: Entering directory `/usr/local/redis/src'
    CC Makefile.dep
make[1]: Leaving directory `/usr/local/redis/src'
make[1]: Entering directory `/usr/local/redis/src'

...
Hint: It's a good idea to run 'make test' ;)

    INSTALL redis-server
    INSTALL redis-benchmark
    INSTALL redis-cli
make[1]: Leaving directory `/usr/local/redis/src'

5、redis启动

为了方便管理，将Redis6.2.6目录中的conf配置文件和常用命令移动到统一目录中。

切换至redis根目录，创建bin和etc文件，将redis.conf文件移动到/usr/local/redis/etc/目录，将mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-server 文件移动到/usr/local/redis/bin/目录。

[root@Java-JingXuan redis]# mkdir etc
[root@Java-JingXuan redis]# mkdir bin
[root@Java-JingXuan redis]# mv redis.conf /usr/local/redis/etc/
[root@Java-JingXuan redis]# cd src/
[root@Java-JingXuan src]# mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-server /usr/local/redis/bin/
[root@Java-JingXuan src]# ll ../bin/
total 37524
-rwxrwxr-x 1 root root     735 Oct  4 18:59 mkreleasehdr.sh
-rwxr-xr-x 1 root root 4829472 Jan 16 22:30 redis-benchmark
-rwxr-xr-x 1 root root 9524032 Jan 16 22:30 redis-check-aof
-rwxr-xr-x 1 root root 9524032 Jan 16 22:30 redis-check-rdb
-rwxr-xr-x 1 root root 5003752 Jan 16 22:30 redis-cli
-rwxr-xr-x 1 root root 9524032 Jan 16 22:30 redis-server

执行redis-server命令，启动redis服务。另外，更多其他软件安装配置步骤，如mysql、kafka、fastdfs、elasticsearch各种版本等中间件安装配置图文步骤，公众号Java精选，回复中间件三个汉字，获取所有软件安装步骤。切勿乱回复，否则什么也没有！！！

6、设置后台启动redis

编辑redis.conf文件，将daemonize属性改为yes，执行vim /usr/local/redis/etc/redis.conf命令。

[root@Java-JingXuan redis]# vim /usr/local/redis/etc/redis.conf

执行./bin/redis-server /usr/local/redis/etc/redis.conf命令，启动redis服务。

[root@Java-JingXuan redis]# ./bin/redis-server /usr/local/redis/etc/redis.conf

7、设置redis密码

编辑redis.conf文件，找到requirepass这个参数，若是没有增加requirepass参数并设置密码参考如下图所示，执行vim /usr/local/redis/etc/redis.conf命令。

保存后，重启redis服务即可生效。

8、设置redis服务远程访问

编辑redis.conf文件，找到bind 127.0.0.1 -::1配置，将用#号注释掉即可，参考如下图所示。

然后执行ps -ef|grep redis命令，找到已启动的redis服务，使用kill命令杀掉redis服务进程。再执行./bin/redis-server /usr/local/redis/etc/redis.conf命令，启动redis服务。

[root@Java-JingXuan redis]# ps -ef|grep redis
root     27715     1  0 22:45 ?        00:00:00 ./bin/redis-server 127.0.0.1:6379
root     29297 25962  0 22:53 pts/4    00:00:00 grep --color=auto redis
[root@Java-JingXuan redis]# kill -9 27715
[root@Java-JingXuan redis]# ./bin/redis-server /usr/local/redis/etc/redis.conf
[root@Java-JingXuan redis]# ps -ef|grep redis
root     29323     1  0 22:53 ?        00:00:00 ./bin/redis-server *:6379
root     29357 25962  0 22:54 pts/4    00:00:00 grep --color=auto redis

使用连接redis服务的客户端连接测试，如下图所示表示连接成功。
