篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Redis install and config相关的知识,希望对你有一定的参考价值。
本文参照官方文档。最初安装redis时,编译后只能在当前目录使用,并且 init 脚本也是参照网络而写。最近在官方看了部分文档,对其编译与使用过程有了进一步了解,遂整理此文,以备查阅。
准备和说明:
系统:centos6.5
软件源码目录:/usr/local/src
软件安装目录:/usr/local/bin
软件官网:redis.io
软件下载地址及版本(截至本文发布最新稳定版):http://download.redis.io/releases/redis-3.0.6.tar.gz
软件安装:
$wget -c -P /usr/local/src $cd /usr/local/src $tar zxvf redis-3.0.6.tar.gz $cd /usr/local/src/redis-3.0.6 #查看REDME得知 #编译安装到当前路径src目录 $sudo make 或 #编译redis并安装到目录/usr/local/bin #此文采用此种方式 $sudo make install 或 #编译redis并安装到自定义目录/usr/local/redis $sudo make prefix=/usr/local/redis
经过上面的编译,生成以下二进制文件
redis-server is the Redis Server itself.
redis-sentinel is the Redis Sentinel executable (monitoring and failover).
redis-cli is the command line interface utility to talk with Redis.
redis-benchmark is used to check Redis performances.
redis-check-aof and redis-check-dump are useful in the rare event of corrupted data files.
完善安装:
在完成以上编译,就已完成redis软件安装,可使用 ./redis-server 运行 redis 服务。但在生产环境这并不可取,所以需要后续工作进行完善。
如只使用 make 编译,请将 server 和 cli 拷贝到 /usr/local/bin 下:
$sudo cp src/redis-server /usr/local/bin $sudo cp src/redis-cli /usr/local/bin
创建配置文件和数据存储目录:
$sudo mkdir /etc/redis $sudo mkdir /var/redis
复制 init 脚本到 /etc/init.d 并使用 redis 加实例端口命名
$sudo utils/redis_init_script /etc/init.d/redis_6379
编辑 init 脚本,修改确认 REDISPORT 端口和 PIDFILE 、CONF 文件路径及名称,增加 chkconfig 级别
$sudo vim /etc/init.d/redis_6379
/etc/init.d/redis_6379
#!/bin/sh # # redis init file for starting up the redis daemon # # chkconfig: - 20 80 # Simple Redis init.d script conceived to work on Linux systems # as it does use of the /proc filesystem. # Source function library. . /etc/rc.d/init.d/functions REDISPORT=6379 EXEC=/usr/local/bin/redis-server CLIEXEC=/usr/local/bin/redis-cli PIDFILE=/var/run/redis_${REDISPORT}.pid CONF="/etc/redis/${REDISPORT}.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 ;; 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" fi ;; *) echo "Please use start or stop as first argument" ;; esac
复制配置模板到 /etc/redis 目录,并以运行实例端口命名
$sudo cp redis.conf /etc/redis/6379.conf
创建运行实例工作目录
$sudo mkdir /var/redis/6379
编辑配置文件,确保以下更改
Set daemonize to yes (by default it is set to no).
Set the pidfile to
/var/run/redis_6379.pid
(modify the port if needed).Change the port accordingly. In our example it is not needed as the default port is already 6379.
Set your preferred loglevel.
Set the logfile to
/var/log/redis_6379.log
Set the dir to /var/redis/6379 (very important step!)
redis.conf
daemonize yes pidfile /var/run/redis_6379.pid port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 0 loglevel notice logfile "/var/log/redis_6379.log" databases 16 save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump.rdb dir /var/redis/6379 slave-serve-stale-data yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 appendonly no appendfilename "appendonly.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-entries 512 list-max-ziplist-value 64 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes
将 redis 加入系统服务,并设置默认运行级别
chkconfig --add redis_6379 chkconfig --level 2345 redis_6379 on
启动 redis 服务
$sudo service redis_6379 start
至此完成安装及配置,可使用 redis-cli 链接 redis 服务测试
