linux 下安装

下载地址：http://redis.io/download，下载最新文档版本。本文使用的最新文档版本为 3.2.7，下载，解压缩和编译安装Redis：

稳定 Redis 3.2包含对API的重大更改和Redis的实现。 Redis 3.2发行说明

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

安装时候可能出错，本文末尾有我自己遇到的错误

启动redis

可以看出默认端口是6379，并且现在的启动不是后台启动。 vi redis.conf 设置 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). _._ _.-``__ ''-._ _.-`` `. `_.

可以看出默认端口是6379，并且现在的启动不是后台启动。

下面我们改redis配置文件让其后台运行

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

默认情况下，Redis不作为守护程序运行。如果需要，使用“yes”。＃注意，Redis在守护进程时会在/var/run/redis.pid中写一个pid文件。守护进程 yes vim redis.conf 设置 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

进入client测试简单命令

[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

打开redis.conf文件修改绑定的ip为本机真实的IP bind 10.10.130.140修改端口号 port 6379守护进程运行 daemonize yes修改进程文件 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

贴出redis启动脚本方便管理

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 #安装路径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路径地址，这里说明一下，在 redis.conf配置文件中需要将 daemonize这个参数项设置为 yes才会在redis启动时生成pid文件，很多新人不知道，没有生成pid文件，所以脚本里根据pid文件关闭redis就失败。如果正常关闭就会删除这个pid文件

写完后保存后,退出

设置redis.conf中daemonize为yes,确保守护进程开启。

设置权限

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

设置开机自启动

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

关机重启测试

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

测试

安装报错

1、不能编译没有GCC 编译工具：

问题1:make时可能会报如下错误

[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:命令没有找到make[3]: *** [net. o] Error 127[3]:* * * 错误127

解决方法：安装gcc

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

2、make时可能会报如下错误：

[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

解决方法：

查找实时库librt所在路径: 在src下的Makefile文件中的函数，加 FINAL_LIBS+= /usr/lib64/librt.so #此路径加上librt.so，即可，在编译就成功了大概在 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 #此路径加上librt.soendif

3.错如下：

[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’

指定目录安装：

[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？下面我们来说一说~
