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 redis
redis: /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.gz
cd redis-2.8.13
make
sudo 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/redis
cp redis-server /usr/redis
cp redis-benchmark /usr/redis
cp redis-cli /usr/redis
cp redis.conf /usr/redis
cd /usr/redis
#配置结束--
或者可以这样配置
mkdir /etc/redis
cp redis.conf /etc/redis/redis.conf
mkdir /var/lib/redis
可从此处下载修改好的 redis.conf
启动redis
redis-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 redis
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ
root 23266 0.0 0.7 137356 7768 ? Sl 00:23 0:04 redis-server *:6379
root 23982 0.0 0.5 19404 5100 pts/0 S+ 01:09 0:00 redis-cli

[root@localhost src]# redis-cli

OK
127.0.0.1:6379> get w
"wang"
127.0.0.1:6379>
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+j
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected> set w 3
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected>
5.启动服务
[root@localhost src]# redis-server
[24502] 28 Oct 01:54:35.784 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
[24502] 28 Oct 01:54:35.784 * Increased maximum number of open files to 10032 (it was originally set to 1024).

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。
