阿里云主机(aliyun-Linux) x64安装Redis详解

如何在Linux上安装Redis呢，下面以阿里云主机linux 64位作为示例进行安装测试：

1、下载源码编译并安装

# wget http://download.redis.io/releases/redis-2.8.19.tar.gz

# tar xzf redis-2.8.19.tar.gz

# cd redis-2.8.19

# make

2、编译成功过后，在src目录下，有三个可执行文件redis-server、redis-benchmark、redis-cli。我这里将其统一放到/usr/local/redis目录下

#mkdir /usr/local/redis

#cp redis-server /usr/redis

#cp redis-benchmark /usr/redis

#cp redis-cli /usr/redis

#cd ../

#cp redis.conf /usr/redis

#cd /usr/redis

3.将redis添加到系统环境变量中：

#vi /etc/profile

在文件最后加入下面代码：

export PATH=/usr/local/redis:$PATH

保存并重新编译

#source /etc/profile

4、启动Redis服务。

#redis-server redis.conf

如果出现类似下面的输出信息则启动成功：

[20466] 04 Mar 16:34:05.702 # Server started, Redis version 2.8.19

[20466] 04 Mar 16:34:05.702 # WARNING overcommit_memory is set to 0! Background

save may fail under low memory condition. To fix this issue add 'vm.overcommit_m

emory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.ove

rcommit_memory=1' for this to take effect.

[20466] 04 Mar 16:34:05.703 # WARNING: The TCP backlog setting of 511 cannot be

enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

[20466] 04 Mar 16:34:05.703 * The server is now ready to accept connections on p

ort 6379

5、测试

#redis-cli

redis> set mydata "Hello Redis"

redis> get mydata

"Hello Redis"
