一、下载包
[root@iZ2ze6bgt1xmvd4jc0v7nmZ src]# wget http://download.redis.io/releases/redis-5.0.3.tar.gz
二、解压
[root@iZ2ze6bgt1xmvd4jc0v7nmZ src]# tar -zxvf redis-5.0.3.tar.gz
三、进入源码目录，并编译
make && make install PREFIX=/usr/local/redis
四、运行
[root@iZ2ze6bgt1xmvd4jc0v7nmZ bin]# cd /usr/local/redis/bin/ [root@iZ2ze6bgt1xmvd4jc0v7nmZ bin]# ./redis-server 7138:C 06 Apr 2021 14:19:46.160 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 7138:C 06 Apr 2021 14:19:46.160 # Redis version=5.0.3, bits=64, commit=00000000, modified=0, pid=7138, just started 7138:C 06 Apr 2021 14:19:46.160 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf _._ _.-``__ ''-._ _.-`` `. `_.

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. 7138:M 06 Apr 2021 14:19:46.161 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled. 7138:M 06 Apr 2021 14:19:46.162 * DB loaded from disk: 0.000 seconds 7138:M 06 Apr 2021 14:19:46.162 * Ready to accept connections
成功后，退出
五、建立/etc/redis目录，用于存放redis配置文件
[root@iZ2ze6bgt1xmvd4jc0v7nmZ bin]# mkdir /etc/redis
将源码目录下的redis.conf文件复制到/etc/redis目录下
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# cp /usr/local/src/redis-5.0.3/redis.conf /etc/redis/
六、修改配置文件，让服务后台启动
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# vim /etc/redis/redis.conf
搜索daemonize，将值no改为yes
daemonize yes
保存退出
七、指定配置文件启动redis
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# /usr/local/redis/bin/redis-server /etc/redis/redis.conf 7394:C 06 Apr 2021 14:26:35.455 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 7394:C 06 Apr 2021 14:26:35.455 # Redis version=5.0.3, bits=64, commit=00000000, modified=0, pid=7394, just started 7394:C 06 Apr 2021 14:26:35.455 # Configuration loaded
八、设置开机自启动
新建 redis.service文件
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# vim /etc/systemd/system/redis.service
添加如下内容
[Unit] Description=redis-server After=network.target [Service] Type=forking ExecStart=/usr/local/redis/bin/redis-server /etc/redis/redis.conf PrivateTmp=true [Install] WantedBy=multi-user.target
保存退出
依次执行如下命令：
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# systemctl daemon-reload
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# systemctl start redis
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# systemctl enable redis Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /etc/systemd/system/redis.service.
查询
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# systemctl enable redis Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /etc/systemd/system/redis.service. [root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# systemctl list-unit-files|grep redis redis.service enabled [root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]#
九、客户端连接数据库
首先设置软连接
[root@iZ2ze6bgt1xmvd4jc0v7nmZ redis-5.0.3]# ln -s /usr/local/redis/bin/redis-cli /usr/bin/
再连接数据库
[root@iZ2ze6bgt1xmvd4jc0v7nmZ home]# redis-cli 127.0.0.1:6379>
