本文将基于Redis 6.2版本进行讲解，并将Redis部署在CentOS 7 64位的虚拟机环境中。视频讲解如下：
下图展示了Redis官方网站提供的Redis下载信息。
提示：由于Redis基于C语言开发，因此在安装CentOS 7的时候需要安装GCC编译器。GCC（GNU Compiler Collection，GNU编译器套件）是由GNU开发的编程语言译器。GNU编译器套件包括C、C++、 Objective-C、 Fortran、Java、Ada和Go语言前端，也包括了这些语言的库。如下图所示。
下面通过具体的步骤来安装部署Redis。
（1）创建Redis的安装目录。
mkdir /root/training/
（2）解压Redis的安装包。
tar -zxvf redis-6.2.6.tar.gz cd redis-6.2.6/
（3）编译Redis，并将其安装到/root/training/redis目录下。
make make PREFIX=/root/training/redis install
（4）将Redis的配置文件redis.conf复制到/root/training/redis/conf目录下。
mkdir /root/training/redis/conf cp redis.conf /root/training/redis/conf
（5）查看Redis的目录结构。
tree /root/training/redis/ 输出的信息如下 /root/training/redis/ ├── bin │ ├── redis-benchmark Redis基准测试工具 │ ├── redis-check-aof -> redis-server AOF持久化文件检测和修复工具 │ ├── redis-check-rdb -> redis-server RDB持久化文件检测和修复工具 │ ├── redis-cli Redis客户端程序 │ ├── redis-sentinel -> redis-server Redis哨兵启动程序 │ └── redis-server Redis服务器端启动程序 └── conf └── redis.conf 2 directories, 7 files
（6）使用vi编辑器修改/root/training/redis/conf/redis.conf的文件。
...... # IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE # INTERFACES JUST COMMENT OUT THE FOLLOWING LINE. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ # bind 127.0.0.1 -::1 注释掉该行 ...... # By default protected mode is enabled. You should disable it only if # you are sure you want clients from other hosts to connect to Redis # even if no authentication is configured, nor a specific set of interfaces # are explicitly listed using the "bind" directive. protected-mode no 将protected-mode改为no ...... ################### GENERAL ################### # By default Redis does not run as a daemon. Use 'yes' if you need it. # Note that Redis will write a pid file in /var/run/redis.pid # when daemonized. # When Redis is supervised by upstart or systemd, this parameter has # no impact. daemonize yes 将daemonize改为yes ......
（7）在默认情况下，Redis没有启用系统日志功能。为了能够更好地监控Redis，建议在生产环境中启用Redis的系统日志。修改/root/training/redis/conf/redis.conf的文件。
...... # Specify the server verbosity level. # This can be one of: # debug (a lot of information, useful for development/testing) # verbose (many rarely useful info, but not a mess like the debug level) # notice (moderately verbose, what you want in production probably) # warning (only very important / critical messages are logged) loglevel notice # Specify the log file name. Also the empty string can be used to force # Redis to log on the standard output. Note that if you use standard # output for logging but daemonize, logs will be sent to /dev/null logfile "/root/training/redis/redis.log" 设置Redis系统日志文件 ......
（8）进入Redis的安装目录，执行bin目录下的redis-server命令启动Redis。
bin/redis-server conf/redis.conf
（9）查看文件/root/training/redis/redis.log的内容。
...... *** #oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo *** #Redis version=6.2.6,bits=64,commit=00000000,modified=0, *** #pid=121814,just started *** #Configuration loaded *** *Increased maximum number of open files to 10032 *** #(it was originally set to 1024). *** *monotonic clock: POSIX clock_gettime *** *Running mode=standalone, port=6379. ...... *** #Server initialized ...... *** *Ready to accept connections ......
提示：从redis.log文件中可以看出，当前Redis实例是一个单节点实例并且Redis Server默认监听6379端口。
（10）使用ps命名查看Redis的后台进程信息。
ps -ef|grep redis 输出的信息如下： root 121814 1 0 09:59 ? 00:00:00 bin/redis-server *:6379 root 121902 116943 0 10:05 pts/1 00:00:00 grep --color=auto redis
（11）使用Redis的客户端工具登录Redis Server。
bin/redis-cli
（12）执行info命令查看Redis Server的统计信息。
127.0.0.1:6379> info 输出的信息如下： # Server redis_version:6.2.6 redis_git_sha1:00000000 redis_git_dirty:0 redis_build_id:d9df5c2d7eb8e995 redis_mode:standalone os:Linux 3.10.0-693.el7.x86_64 x86_64 arch_bits:64 ......
