简介
Redis
是一个开源(BSD
许可),内存存储的数据结构服务器,是一个高性能的key-value
数据库,高速缓存和消息队列代理。它支持字符串、哈希表、列表、集合、有序集合,位图,hyperloglogs
等数据类型。内置复制、Lua脚本、LRU收回、事务以及不同级别磁盘持久化功能,同时通过Redis Sentinel
提供高可用,通过Redis Cluster
提供自动分区。
下载与安装
wget http://download.redis.io/releases/redis-4.0.1.tar.gz
tar xzf redis-4.0.1.tar.gz
cd redis-4.0.1
make
make isntall
服务管理
通过指定配置文件启动
sudo redis-server /opt/redis-4.0.1/redis.conf
22090:C 20 Sep 09:52:39.951 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
22090:C 20 Sep 09:52:39.951 # Redis version=4.0.1, bits=64, commit=00000000, modified=0, pid=22090, just started
22090:C 20 Sep 09:52:39.951 # Configuration loaded
如果输出如上信息,证明Redis服务已经启动成功。
通过命令redis-server 启动
redis-server
关闭Redis服务
redis-cli shutdown
客户端登陆并验证
redis-cli
127.0.0.1:6379> set a b
OK
127.0.0.1:6379> get a
“b”
127.0.0.1:6379> exit
设置redis开机启动
创建Redis配置目录
sudo mkdir /etc/redis
拷贝配置文件
sudo cp /opt/redis-4.0.1/redis.conf /etc/redis/
修改目录/etc/redis/
下面的redis.conf
文件,将以下内容
> daemonize no
> logfile ""
修改为:
#打开后台运行选项
daemonize yes
#设置日志文件路径
logfile “/var/log/redis/redis.log”
#!/bin/sh
# chkconfig: 2345 10 90
# description: Start and Stop redis
PATH=/usr/local/bin
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis.pid
CONF="/etc/redis/redis.conf"
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|fore-reload}"
exit 1
esac
问题一
insserv: warning: script ‘K01redis’ missing LSB tags and overrides
解决方法
安装一个中文语言,系统就知道zh_CN.UTF-8
了,这个时候用perl就不会报错了
sudo apt-get install language-pack-zh-hans
问题二
insserv: warning: script ‘redis’ missing LSB tags and overrides
解决方法
修改目录/etc/init.d/
下面的redis
文件,在文件头部#!/bin/sh
下面添加如下内容:
### BEGIN INIT INFO
# Provides: OSSEC HIDS
# Required-Start: $network $remote_fs $syslog $time
# Required-Stop:
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: OSSEC HIDS
### END INIT INFO
使用脚本启动服务
- 开启redis:
service redis start
- 停止redis:
service redis stop
- 重启redis:
service redis restart
- 查看服务状态:
service redis status
