redis安装与配置

redis安装

1、下载redis

下载地址http://redis.io/download

2、安装redis

下载后解压 tar zxvf redis-3.0.6.tar.gz 到任意目录，例如/usr/local/redis

解压后，进入redis目录

cd /usr/local/redis
make
cp redis.conf /etc/ 这个文件时redis启动的配置文件
cp redis-benchmark redis-cli redis-server /usr/bin/

3、启动redis服务

[root@localhost ~]# redis-server /etc/redis.conf

6229:M 22 Jan 14:03:11.099 * The server is now ready to accept connections on port 6379

查看进程，确认redis已经启动

[root@localhost ~]# ps -ef|grep redis
root      6229  2270  0 14:03 pts/0    00:00:00 redis-server *:6379
root      6257  6236  0 14:04 pts/1    00:00:00 grep redis

上面的启动方法并没有在后台启动，修改redis.conf，设置redis进程为后台守护进程

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize yes              #redis后台运行
dir /usr/local/redis       #指定持久化文件保存路径

4、测试redis

[root@localhost ~]# redis-cli
127.0.0.1:6379> set name songbin
OK
127.0.0.1:6379> get name
"songbin"

5、关闭redis服务

[root@localhost ~]#redis-cli shutdown

6、自启动脚本

[root@localhost redis]# cp utils/redis_init_script /etc/init.d/redis
[root@localhost redis]#vi /etc/init.d/redis
#chkconfig: 2345 80 90
REDISPORT=6379
EXEC=/usr/bin/redis-server
CLIEXEC=/usr/bin/redis-cli
PIDFILE=/var/run/redis.pid
CONF="/etc/redis.conf"

添加 #chkconfig: 2345 80 90

并修改配置文件路径 ，以及redis-server路径

[root@localhost redis]# chkconfig --add redis
[root@localhost redis]# chkconfig redis on
[root@localhost redis]# service redis start
Starting Redis server...
