Redis的安装与使用
http://download.redis.io/releases/redis-3.0.2.tar.gz
(1)基础安装
--下载后解压
/home/www/redis-3.0.2
--安装
make
报错:
error: jemalloc/jemalloc.h: No such file or directory
--解决
make MALLOC=libc
原因:jemalloc是默认的分配器,系统没有jemalloc仅仅有libc
再次运行make就可以安装完毕!
(2)多port多实例安装(可參考http://blog.csdn.net/xu470438000/article/details/42971091文章,涉及到集群)
在/home/www/redis-3.0.2建立文件夹cluster
mkdir -p /home/www/redis-3.0.2/cluster
--在该文件夹下建立三个文件夹
mkdir 6379
mkdir 6380
mkdir 6381
--把redis.conf文件复制到6379下:
cp /home/www/redis-3.0.2/redis.conf /home/www/redis-3.0.2/cluster/6379
--改动配置(眼下仅仅改动前两项也能够)
pidfile /var/run/redis-6379.pid #当执行多个redis要指定不同PID
port 6379 #端口号
daemonize yes #是否以守护进程启动
cluster-enabled yes #开启集群模式
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
logfile /var/log/redis/redis-6379.log #配置日志文件位置
--同理把redis.conf拷贝到6380、6381下改动port
cp /home/www/redis-3.0.2/cluster/6379/redis.conf /home/www/redis-3.0.2/cluster/6380/
cp /home/www/redis-3.0.2/cluster/6379/redis.conf /home/www/redis-3.0.2/cluster/6381/
--启动服务
/home/www/redis-3.0.2/src/redis-server /home/www/redis-3.0.2/cluster/6379/redis.conf
/home/www/redis-3.0.2/src/redis-server /home/www/redis-3.0.2/cluster/6380/redis.conf
/home/www/redis-3.0.2/src/redis-server /home/www/redis-3.0.2/cluster/6381/redis.conf
--查看port
ps -ef|grep redis
--连接6380库(命令行)
/home/www/redis-3.0.2/src/redis-cli -h 192.168.5.128 -p 6380
启动后依据conf配置会创建/var/run/redis-6379.pid进程(在redis.conf中配置)
--关闭某个port
/home/www/redis-3.0.2/src/redis-cli -p 6379 shutdown
--批量模糊删除键
redis-cli -p 6381 KEYS "t_hash:*" | xargs redis-cli -p 6381 del
至此多port已安装完毕!
(3)启动脚本
#!/bin/sh
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379 #实际环境而定
EXEC=/home/www/redis-3.0.2/src/redis-server #实际环境而定
REDIS_CLI=/home/www/redis-3.0.2/src/redis-cli #实际环境而定
PIDFILE=/var/run/redis-6379.pid #实际环境而定
CONF="/home/www/redis-3.0.2/cluster/6379/redis.conf" #实际环境而定
case "$1" in
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed."
else
echo "Starting Redis server..."
$EXEC $CONF
fi
if [ "$?"="0" ]
then
echo "Redis is running..."
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE exists, process is not running."
else
PID=$(cat $PIDFILE)
echo "Stopping..."
$REDIS_CLI -p $REDISPORT SHUTDOWN
while [ -x $PIDFILE ]
do
echo "Waiting for Redis to shutdown..."
sleep 1
done
echo "Redis stopped"
fi
;;
restart|force-reload)
${0} stop
${0} start
;;
*)
echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
exit 1
esac
--创建脚本
mkdir /etc/init.d/redis-6379
chmod +x /etc/init.d/redis-6379
--启动、停止
service redis-6379 start|stop
(5)开机增加自启动
chkconfig redis-6379 on
chkconfig redis-6380 on
chkconfig redis-6381 on
报错:service redis does not support chkconfig
解决方法:(必须把以下两行凝视放在/etc/init.d/redis文件靠前的凝视中)
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
上面的凝视的意思是。redis服务必须在执行级2,3,4,5下被启动或关闭,启动的优先级是90。关闭的优先级是10。
(6)使用client
下载Redis DeskTop Managerclient Add New Connection
name:192.168.5.128--6380
host:192.168.5.128
port:6380
auth:(此处默认没有值。为安全起见会设置password)
