有时需要离线安装redis,所以需要redis离线安装包,不同的centos版本和redis版本,依赖包不同,本例中,centos: CentOS Linux release 7.0.1406 (Core),Basic Web Server版本,自动下载的redis版本为3.2.12
1、检查是否存在redis安装包
yum search redis
2、若未找到redis安装包,则安装epel-release源
yum -y install epel-release
3、再次查询仓库中是否存在redis,若出现如下异常,则在/usr/lib/python2.7/site-packages/urlgrabber/grabber.py中1510行左右将elif errcode in (42, 55, 56) 改为elif errcode == 42 ,然后再次查询
[root@localhost ~]# yum search redis
Loaded plugins: fastestmirror, langpacks

KeyboardInterrupt
4、正常查询,出现
redis.x86_64 : A persistent key-value database
则源安装成功
5、下载安装包
yum install --downloadonly --downloaddir=/work redis
出现
exiting because "Download Only" specified
下载结束,查看redis
[root@localhost ~]# whereis redis
redis:[root@localhost ~]# ll /work/
total 660
-rw-r--r--. 1 root root 107040 Apr 2 2014 jemalloc-3.6.0-1.el7.x86_64.rpm
-rw-r--r--. 1 root root 556969 Oct 26 15:10 redis-3.2.12-2.el7.x86_64.rpm
[root@localhost ~]#
redis安装包及依赖包下载完成,并且没有安装
6、安装
rpm -ivh /work/*
安装结束后,查看redis安装情况
[root@localhost ~]# whereis redis
redis: /etc/redis.conf
7、启动redis(开机启动文件在redis安装完成后,自动放入/usr/lib/systemd/system/中)
systemctl start redis
/usr/lib/systemd/system/redis.service
[Unit]
Description=Redis persistent key-value database
After=network.target
After=network-online.target
Wants=network-online.target
[Service]

ExecStop=/usr/libexec/redis-shutdown
Type=notify
User=redis
Group=redis
RuntimeDirectory=redis
RuntimeDirectoryMode=0755
[Install]
WantedBy=multi-user.target
8、登录
[root@localhost ~]# redis-cli
127.0.0.1:6379>
这种方式看似方便,但redis官方不推荐这种方式来安装redis,因为这种方式安装的redis不是当前最新的可用版本。当前稳定版本是5.0.4,但目前通过yum下载到的版本是3.2.12.
