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

tar -zxf redis-2.2.13.tar.gz

cd redis-2.2.13

make

sudo make install

cp redis.conf /etc

install的时候,redis的命令会被拷贝到/usr/local/bin下面

2,建立用户与日志目录

第一次启动Redis前,建议为Redis单独建立一个用户,并新建data和日志文件夹

sudo useradd redis

sudo mkdir -p /var/lib/redis

sudo mkdir -p /var/log/redis

sudo chown redis.redis /var/lib/redis #db文件放在这里,要修改redis.conf

sudo chown redis.redis /var/log/redis


3,配置init脚本

其实github上很多老外写好的启动脚本,不过大部分都是ubuntu的,对于Centos,也有一份

把上述代码存为redis,放到/etc/init.d/下面

1

chmod +x /etc/init.d/redis


其实做成服务启动,也是调用redis-server,如果想让它在后台作为daemon运行,那么

需要修改redis.conf,将 daemonize no 改为 daemonize yes

4,设定开机启动服务

1

sudo chkconfig redis on


5,启动,停止redis
启动:

1

service redis start #或者 /etc/init.d/redis start

停止:

1

service redis stop #或者 /etc/init.d/redis stop


6,测试redis

redis-cli

redis 127.0.0.1:6379> set foo 123

OK

redis 127.0.0.1:6379> get foo

"123"

redis 127.0.0.1:6379> exit
