一、Redis yum安装方法
1、根据操作系统，下载相应的epel源
epel(RHEL 7)
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
epel(RHEL 6)
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
epel(RHEL 5)
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-5.repo
2、查看epel源是否存在
[root@localhost ~]# ll /etc/yum.repos.d/
总用量 32
drwxr-xr-x 2 root root 4096 7月 31 22:57 bak
-rw-r--r--. 1 root root 1991 3月 28 2017 CentOS-Base.repo
-rw-r--r--. 1 root root 647 3月 28 2017 CentOS-Debuginfo.repo
-rw-r--r--. 1 root root 289 3月 28 2017 CentOS-fasttrack.repo
-rw-r--r--. 1 root root 630 3月 28 2017 CentOS-Media.repo
-rw-r--r--. 1 root root 7989 3月 28 2017 CentOS-Vault.repo
-rw-r--r-- 1 root root 664 5月 11 11:34 epel.repo
3、通过外部源安装redis
[root@localhost ~]# yum -y install redis 安装方法
[root@localhost ~]# rpm -ql redis
/etc/logrotate.d/redis
/etc/rc.d/init.d/redis #redis服务启动文件
/etc/rc.d/init.d/redis-sentinel #redis哨兵启动文件
/etc/redis-sentinel.conf #redis哨兵配置文件
/etc/redis.conf #配置文件
/etc/security/limits.d/95-redis.conf
/usr/bin/redis-benchmark
/usr/bin/redis-check-aof
/usr/bin/redis-check-rdb
/usr/bin/redis-cli #redis客户端
/usr/bin/redis-sentinel #redis哨声
/usr/bin/redis-server #redis-server服务
/usr/libexec/redis-shutdown
/var/lib/redis
/var/log/redis #日志存放路径
/var/run/redis #redis_pid 存放路径
4、redis 配置文件理解
[root@localhost ~]# cat /etc/redis.conf | grep -v '#' | grep -v '^$'
