linux 下安裝

下載地址：http://redis.io/download，下載最新文檔版本。本文使用的最新文檔版本為 3.2.7，下載，解壓縮和編譯安裝Redis：

穩定 Redis 3.2包含對API的重大更改和Redis的實現。 Redis 3.2發行說明

wget http://download.redis.io/releases/redis-3.2.7.tar.gztar xzf redis-3.2.7.tar.gzcd redis-3.2.7make

安裝時候可能出錯，本文末尾有我自己遇到的錯誤

啟動redis

可以看出默認端口是6379，并且現在的啟動不是后臺啟動。 vi redis.conf 設置 daemonize no–>daemonize yes

[root@souyunku redis-3.2.7]# ./bin/redis-server ./redis.conf 8258:M 08 Feb 12:26:54.279 * Increased maximum number of open files to 10032 (it was originally set to 1024). _._ _.-``__ ''-._ _.-`` `. `_.

可以看出默認端口是6379，并且現在的啟動不是后臺啟動。

下面我們改redis配置文件讓其后臺運行

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

默認情況下，Redis不作為守護程序運行。如果需要，使用“yes”。＃注意，Redis在守護進程時會在/var/run/redis.pid中寫一個pid文件。守護進程 yes vim redis.conf 設置 daemonize no 把‘no’修改>daemonize yes

[root@souyunku redis-3.2.7]# vi redis.conf [root@souyunku redis-3.2.7]# ./bin/redis-server ./redis.conf [root@souyunku redis-3.2.7]# ps -ef | grep redroot 8264 1 0 12:34 ? 00:00:00 ./bin/redis-server 127.0.0.1:6379root 8268 8023 0 12:34 pts/1 00:00:00 grep red

進入client測試簡單命令

[root@souyunku redis-3.2.7]# cd bin/[root@souyunku bin]# ./redis-cli 127.0.0.1:6379> set name yanpengleiOK127.0.0.1:6379> get name"yanpenglei"127.0.0.1:6379>

修改配置文件

打開redis.conf文件修改綁定的ip為本機真實的IP bind 10.10.130.140修改端口號 port 6379守護進程運行 daemonize yes修改進程文件 pidfile /var/run/redis_6380.pid修改日志文件 logfile "/home/software/redis-3.2.7/log/redis.log"修改持久化文件 dir /usr/software/redis-3.2.7/datas

貼出redis啟動腳本方便管理

vim /etc/rc.d/init.d/redisd#!/bin/sh#chkconfig: 345 86 14#description: Startup and shutdown script for RedisPROGDIR=/opt/redis/redis-3.2.7 #安裝路徑PROGNAME=bin/redis-serverDAEMON=$PROGDIR/$PROGNAMECONFIG=/opt/redis/redis-3.2.7/redis.confPIDFILE=/var/run/redis_6379.pidDESC="redis daemon"SCRIPTNAME=/etc/rc.d/init.d/redisdstart(){ if test -x $DAEMON then echo -e "Starting $DESC: $PROGNAME" if $DAEMON $CONFIG then echo -e "OK" else echo -e "failed" fi else echo -e "Couldn't find Redis Server ($DAEMON)" fi}stop(){ if test -e $PIDFILE then echo -e "Stopping $DESC: $PROGNAME" if kill `cat $PIDFILE` then echo -e "OK" else echo -e "failed" fi else echo -e "No Redis Server ($DAEMON) running" fi}restart(){ echo -e "Restarting $DESC: $PROGNAME" stop start}list(){ ps aux | grep $PROGNAME}case $1 in start) start ;; stop) stop ;; restart) restart ;; list) list ;; *) echo "Usage: $SCRIPTNAME {start|stop|restart|list}" >&2 exit 1 ;;esacexit 0

注意：PIDFILE=/var/run/redis_6379.pid

redis.conf配置文件中指定的pid路徑地址，這里說明一下，在 redis.conf配置文件中需要將 daemonize這個參數項設置為 yes才會在redis啟動時生成pid文件，很多新人不知道，沒有生成pid文件，所以腳本里根據pid文件關閉redis就失敗。如果正常關閉就會刪除這個pid文件

寫完后保存后,退出

設置redis.conf中daemonize為yes,確保守護進程開啟。

設置權限

cd /etc/rc.d/init.d/chmod 755 redisd

設置開機自啟動

cd /etc/rc.d/init.d/chkconfig redisd on

關機重啟測試

reboot然后在用redis-cli測試即可。[root@souyunku ~]# cd /opt/redis/redis-3.2.7/bin/[root@souyunku bin]# ./redis-cli 127.0.0.1:6379> get name(nil)

測試

安裝報錯

1、不能編譯沒有GCC 編譯工具：

問題1:make時可能會報如下錯誤

[root@souyunku redis-3.2.7]# make gcc -std=c99 -pedantic -c -O3 -fPIC -Wall -W -Wstrict-prototypes -Wwrite-strings -g -ggdb net.cmake[3]: gcc: Command not found[3]:gcc:命令沒有找到make[3]: *** [net. o] Error 127[3]:* * * 錯誤127

解決方法：安裝gcc

yum install -y gcc g++ gcc-c++ make

2、make時可能會報如下錯誤：

[root@souyunku redis-3.2.7]# make ../deps/jemalloc/lib/libjemalloc.a(nstime.o): In function `nstime_get':/opt/redis/redis-3.2.7/deps/jemalloc/src/nstime.c:120: undefined reference to `clock_gettime'collect2: ld returned 1 exit statusmake: *** [redis-server] Error 1

解決方法：

查找實時庫librt所在路徑: 在src下的Makefile文件中的函數，加 FINAL_LIBS+= /usr/lib64/librt.so #此路徑加上librt.so，即可，在編譯就成功了大概在 105 ~110 行

ifeq ($(MALLOC),jemalloc) DEPENDENCY_TARGETS+= jemalloc FINAL_CFLAGS+= -DUSE_JEMALLOC -I../deps/jemalloc/include FINAL_LIBS+= ../deps/jemalloc/lib/libjemalloc.aFINAL_LIBS+= /usr/lib64/librt.so #此路徑加上librt.soendif

3.錯如下：

[root@souyunku redis-3.2.7]# make cd src && make all make[1]: Entering directory `/opt/redis/redis-3.2.7/src’

Hint: It’s a good idea to run ‘make test’ ;)

make[1]: Leaving directory `/opt/redis/redis-3.2.7/src’

指定目錄安裝：

[root@souyunku redis-3.2.7]# make PREFIX=/opt/redis/redis-3.2.7 install cd src && make installmake[1]: Entering directory `/opt/redis/redis-3.2.7/src'Hint: It's a good idea to run 'make test' ;) INSTALL install INSTALL install INSTALL install INSTALL install INSTALL installmake[1]: Leaving directory `/opt/redis/redis-3.2.7/src'[root@souyunku redis-3.2.7]#

bin下的命令是什么意思呢？下面我們來說一說~

[root@souyunku bin]# lltotal 30824-rwxr-xr-x. 1 root root 6725486 Feb 8 12:18 redis-benchmark-rwxr-xr-x. 1 root root 22193 Feb 8 12:18 redis-check-aof-rwxr-xr-x. 1 root root 8974545 Feb 8 12:18 redis-check-rdb-rwxr-xr-x. 1 root root 6853618 Feb 8 12:18 redis-clilrwxrwxrwx. 1 root root 12 Feb 8 12:18 redis-sentinel -> redis-server-rwxr-xr-x. 1 root root 8974545 Feb 8 12:18 redis-serverredis-benchmark ---->redis性能測試工具redis-check-aof ---->檢查aof日志工具，如果日志損壞能檢查出來redis-check-dump ---->檢查rdb日志工具redis-cli ---->連接用的客戶端redis-server ---->redis服務區進程
