Redis 介绍
1. 介绍¶
下载安装,在官网找到最新最稳定的下载地址
root@manage01:/usr/local/src# wget http://download.redis.io/releases/redis-5.0.3.tar.gz --2019-03-11 11:11:06-- http://download.redis.io/releases/redis-5.0.3.tar.gz Resolving download.redis.io (download.redis.io)... 109.74.203.151 Connecting to download.redis.io (download.redis.io)|109.74.203.151|:80... connected.

make完后 redis-5.0.3目录下会出现编译后的redis服务程序redis-server,还有用于测试的客户端程序redis-cli,两个程序位于安装目录 src 目录下：下面启动redis服务.
2. 配置¶
root@manage01:/usr/local/redis-s/src# cp -aR redis-check-aof redis-check-rdb redis-cli redis-sentinel redis-server redis-trib.rb redis-benchmark /usr/local/redis/bin/ root@manage01:/usr/local/redis-s/src# cp ../redis.conf /usr/local/redis/conf/ root@manage01:~# cat /usr/local/redis/conf/redis.conf daemonize yes pidfile "/usr/local/redis/log/redis.pid" port 6379 timeout 300 loglevel debug logfile "/usr/local/redis/log/redis.log" databases 16 save 900 1 save 300 10 save 60 10000 rdbcompression yes dbfilename "dump.rdb" dir "/usr/local/redis/data" appendonly no appendfsync always bind 0.0.0.0
参数解释
daemonize no（默认），改成 yes，意思是是否要后台启动。
root@manage01:~# cd /usr/local/redis
root@manage01:/usr/local/redis# tree .

中间有省略，最终是这样
3. 配置环境变量¶
root@manage01:~# grep redis /etc/profile export PATH=$PATH:/usr/local/redis/bin root@manage01:~# source /etc/profile
4. 启动脚本¶
root@manage01:/usr/local/redis/conf# cat /etc/init.d/redis
#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
#
REDISPORT=6379
EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
PIDFILE=/usr/local/redis/log/redis.pid
CONF="/usr/local/redis/conf/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
echo $(ps aux|grep redis|grep -v grep|grep 6379|awk '{print $2}')>$PIDFILE
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$CLIEXEC -p $REDISPORT shutdown
while [ -x /proc/${PID} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped"
cd /usr/local/redis/log/ && rm -f redis.pid
fi
;;
*)
echo "Please use start or stop as first argument"
;;
esac
root@manage01:/usr/local/redis/conf# chmod +x /etc/init.d/redis
5. 启动与停止¶
root@manage01:/usr/local/redis/conf# /etc/init.d/redis stop Stopping ... Redis stopped root@manage01:/usr/local/redis/conf# !p pwd /usr/local/redis/conf root@manage01:/usr/local/redis/conf# !ps ps axf|grep redis 11619 pts/18 S+ 0:00 | \_ grep --color=auto redis root@manage01:/usr/local/redis/conf# /etc/init.d/redis start Starting Redis server... root@manage01:/usr/local/redis/conf# !ps ps axf|grep redis 11634 pts/18 S+ 0:00 | \_ grep --color=auto redis 11622 ? Ssl 0:00 /usr/local/redis/bin/redis-server 0.0.0.0:6379
6. 基本测试¶
root@manage01:~# redis-cli 127.0.0.1:6379> keys * (empty list or set) 127.0.0.1:6379> set k1 v1 OK 127.0.0.1:6379> get k1 "v1" 127.0.0.1:6379> root@manage01:~# redis-cli 127.0.0.1:6379> get k1 "v1" 127.0.0.1:6379> root@manage01:~# pkill redis root@manage01:~# !ps ps axf|grep redis 11273 pts/18 S+ 0:00 | \_ grep --color=auto redis root@manage01:~# redis-server /usr/local/redis/conf/redis.conf root@manage01:~# ps axf|grep redis 11282 pts/18 S+ 0:00 | \_ grep --color=auto redis 11277 ? Ssl 0:00 redis-server 0.0.0.0:6379 root@manage01:~# redis-cli 127.0.0.1:6379> keys * 1) "k1" 127.0.0.1:6379> get k1 "v1"
