系统：CentOS7
Redis:5.0.5
获取最新版本redis：https://redis.io/download ，下载Stable版本，当前安装版本5.0.5
一、安装Redis
1、下载redis安装包(安装目录/usr/local/)
[root@iZbp12y6fwj9mup08bgko6Z ~]# cd /usr/local/ [root@iZbp12y6fwj9mup08bgko6Z local]# wget http://download.redis.io/releases/redis-5.0.5.tar.gz
2、解压redis-5.0.5.tar.gz
[root@iZbp12y6fwj9mup08bgko6Z local]# tar -xzf redis-5.0.5.tar.gz
3、进入解压的redis目录，通过make命令进行编译
[root@iZbp12y6fwj9mup08bgko6Z local]# cd redis-5.0.5 [root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# make
4、执行make test验证编译是否成功(可能会报错，但是不要怕一步一步解决错误，直至成功)
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# make test cd src && make test make[1]: Entering directory `/usr/local/redis-5.0.5/src' CC Makefile.dep make[1]: Leaving directory `/usr/local/redis-5.0.5/src' make[1]: Entering directory `/usr/local/redis-5.0.5/src' You need tcl 8.5 or newer in order to run the Redis test make[1]: *** [test] Error 1 make[1]: Leaving directory `/usr/local/redis-5.0.5/src' make: *** [test] Error 2
###### 很不巧，我的编译错误了，根据错误提示是tcl的问题，所有我要安装一下tcl，你需要根据你的结果信息来处理
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# yum install -y tcl ...... Install 1 Package Total download size: 1.9 M Installed size: 4.4 M Downloading packages: tcl-8.5.13-8.el7.x86_64.rpm | 1.9 MB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : 1:tcl-8.5.13-8.el7.x86_64 1/1 Verifying : 1:tcl-8.5.13-8.el7.x86_64 1/1 Installed: tcl.x86_64 1:8.5.13-8.el7 Complete! [root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]#
###### tcl安装完成后重新运行make test
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# make test ...... !!! WARNING The following tests failed: *** [err]: Active defrag big keys in tests/unit/memefficiency.tcl Expected condition '$max_latency <= 120' to be true (258 <= 120) Cleanup: may take some time... OK make[1]: *** [test] Error 1 make[1]: Leaving directory `/usr/local/redis-5.0.5/src' make: *** [test] Error 2
######此错误是由于所测试的阿里云ECS服务器配置过低造成的延迟太大，可以忽略。
忽略警告，继续安装
6、运行make install命令，将命令安装到/usr/local/bin目录
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# make install cd src && make install make[1]: Entering directory `/usr/local/redis-5.0.5/src' Hint: It's a good idea to run 'make test' ;) INSTALL install INSTALL install INSTALL install INSTALL install INSTALL install make[1]: Leaving directory `/usr/local/redis-5.0.5/src' [root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]#
7、启动服务器
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# redis-server
8、另开一个命令窗口，进行测试，可以看到通过redis-cli命令连接redis之后，输入ping，redis会为我们返回PONG
[root@iZbp12y6fwj9mup08bgko6Z ~]# redis-cli 127.0.0.1:6379> ping PONG 127.0.0.1:6379>
二、设置redis
1、复制redis配置文件，将redis目录的redis.conf复制到/etc/redis目录下
root@iZbp12y6fwj9mup08bgko6Z ~]# find / -name redis.conf /usr/local/redis-5.0.5/redis.conf [root@iZbp12y6fwj9mup08bgko6Z ~]# mkdir /etc/redis [root@iZbp12y6fwj9mup08bgko6Z ~]# cp /usr/local/redis-5.0.5/redis.conf /etc/redis/redis.conf
2、设置可以远程登录，编辑/etc/redis/redis.conf配置文件，注释掉bind 127.0.0.1，如下图：
3、修改默认端口6379，编辑/etc/redis/redis.conf配置文件，如下图：
同时修改pidfile，将其改为pidfile /var/run/redis_6379.pid,修改目的是为了文件名上的端口和实际端口保持一致，方便通过服务方式启动、停止，如后面设置开机启动
4、设置redis服务后台运行，编辑/etc/redis/redis.conf配置文件，将daemonize设置为yes，如下图
5、设置访问密码，编辑/etc/redis/redis.conf配置文件，去掉requirepass行的注释或添加一行，如下图
6、启动redis并指定配置文件为我们刚才修改的/etc/redis/redis.conf配置文件，服务启动后就不像前面那样输出redis图形信息的内容了。
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# redis-server /etc/redis/redis.conf 21262:C 27 Jun 2020 17:21:47.055 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 21262:C 27 Jun 2020 17:21:47.055 # Redis version=5.0.5, bits=64, commit=00000000, modified=0, pid=21262, just started 21262:C 27 Jun 2020 17:21:47.055 # Configuration loaded [root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]#
7、新开一窗口测试链接
[root@iZbp12y6fwj9mup08bgko6Z ~]# 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>
也可以通过-p指定端口访问
[root@iZbp12y6fwj9mup08bgko6Z ~]# redis-cli -p 6379 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>
由于开启了远程访问，所以在其他电脑上也可以访问，通过-h指定ip，-p指定端口：
[iypocket@smac src] ./redis-cli -p 6380 -h 192.168.16.125 192.168.16.125:6379> ping (error) NOAUTH Authentication required. 192.168.16.125:6379> auth 123456 OK 192.168.16.125:6379> ping PONG 192.168.16.125:6379>
8、停止服务
三、设置redis开机启动
1、复制开机启动脚本，在redis目录的utils包下，有一个redis_init_script文件，我们复制到/etc/init.d/目录下，并将文件名改为redis。
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# find / -name redis_init_script /usr/local/redis-5.0.5/utils/redis_init_script [root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# cp /usr/local/redis-5.0.5/utils/redis_init_script /etc/init.d/redis
2、(非必须)修改/etc/redis/redis.conf文件名为/etc/redis/6379.conf，此修改非必须，不修改的话可以在步骤3指定配置文件路径
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# mv /etc/redis/redis.conf /etc/redis/6379.conf
3、编辑/etc/init.d/redis启动脚本，脚本说明如下：
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# vim /etc/init.d/redis
说明
4、测试启动脚本,启动服务systemctl start redis,停止服务systemctl stop redis
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# systemctl start redis [[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# systemctl stop redis
5、设置开机启动
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# chkconfig --add redis
6、重启系统，redis服务即随系统启动。
[root@iZbp12y6fwj9mup08bgko6Z redis-5.0.5]# reboot
