ubuntu系统上部署redis

redis是一个开源、支持网络、基于内存、键值对存储数据库，根据DB-Engines.com的数据显示，redis是最流行的键值对存储数据库。

wget http://redis.googlecode.com/files/redis-2.6.16.tar.gz
sudo tar xzvf redis-2.6.16.tar.gz -C /usr/local/
cd /usr/local/redis-2.6.16/src
sudo make test

make test执行时出现的问题：You need tcl 8.5 or newer in order to run the Redis test
解决方法：安装tcl 8.6

sudo wget http://downloads.sourceforge.net/tcl/tcl8.6.0-src.tar.gz
sudo tar xzvf tcl8.6.0-src.tar.gz -C /usr/local/
cd /usr/local/tcl8.6.0/unix/
sudo ./configure
sudo make
sudo make install
测试：sudo make shell（exit退出）

继续安装redis：

sudo make test
出现“\o/ All tests passed without errors!”表示成功！
sudo ./redis-server /usr/local/redis-2.6.11/redis.conf

在启动redis时，出现以下警告信息：

WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.

安装警告提示，即可解决问题：

     

在/etc/sysctl.conf中添加vm.overcommit_memory = 1
sudo sysctl vm.overcommit_memory=1

sudo make install   会在redis的安装目录的bin目录下生成一些redis命令
ls /usr/local/bin/
cd ../utils/
sudo ./install_server.sh 使用默认的即可
Please select the redis port for this instance: [6379] 6379
Please select the redis config file name [/etc/redis/6379.conf]
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log]
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379]
Selected default - /var/lib/redis/6379
Please select the redis executable path [/usr/local/bin/redis-server]

启动、关闭redis
sudo /etc/init.d/redis_6379 stop
sudo netstat -tunlp | grep redis
sudo /etc/init.d/redis_6379 start
sudo netstat -tunlp | grep redis

redis到此就安装成功！
