NoSQL之Redis - CentOS 6.5安装测试

1.下载redis

可以在线安装或者下载 redis

①在线安装前需要检测是否存在rpm包不存在的话查看yum在线是否存在rpm包不存在的话就只能手动下载或者用别的方式下载

[root@localhost ~]# rpm -qa|grep redis[root@localhost ~]# yum list|grep redis

说明不存在。

②去官网下载或者在线下载

wget http://redis.googlecode.com/files/redis-2.2.13.tar.gz

官网下载好的 redis 已经存在博客中了点击下载 redis。

2.安装

由于是tar.gz格式的所以需要解压安装

下载好之后查找下载文件所在路径

[root@localhost ~]# whereis redisredis: /etc/redis[root@localhost ~]#

解压编译redis的软件包需要有gcc环境

总之缺少什么安装什么。

tar -zxvf reids-2.8.13.tar.gzcd redis-2.8.13makesudo make install#配置开始---编译完成后在Src目录下有四个可执行文件redis-server、redis-benchmark、redis-cli和redis.conf。然后拷贝到一个目录下。mkdir /usr/rediscp redis-server  /usr/rediscp redis-benchmark /usr/rediscp redis-cli  /usr/rediscp redis.conf  /usr/rediscd /usr/redis#配置结束--

或者可以这样配置

mkdir /etc/rediscp redis.conf /etc/redis/redis.confmkdir  /var/lib/redis

可从此处下载修改好的 redis.conf

启动redisredis-server /etc/redis/redis.conf#即可在后台启动redis服务确认运行了之后可以用redis-benchmark命令测试看看还可以通过redis-cli命令实际操作一下比如#install的时候redis的命令会被拷贝到/usr/local/bin下面

3.测试

客户端测试一下是否启动成功

[root@localhost src]# ps -aux|grep redisWarning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQroot     23266  0.0  0.7 137356  7768 ?

4.关闭服务

redis-cli shutdown如果端口变化可以指定端口:redis-cli -p 6379 shutdown

127.0.0.1:6379> i+jCould not connect to Redis at 127.0.0.1:6379: Connection refusednot connected> set w 3Could not connect to Redis at 127.0.0.1:6379: Connection refusednot connected>

5.启动服务

启动之后最好重新打开个窗口运行redsi-cli进入控制台

否则可能出现连接错误。和windows下cmd运行tomcat类似。
