1.下载
下载地址:http://www.redis.io/download
选取当前最新版本3.2.1下载,上传到linux上,进行解压缩:
[[email protected] redis]# ls
redis-3.2.1 redis-3.2.1.tar.gz
2.编译安装
进入redis-3.2.1目录下,运行make进行安装编译:
[[email protected] redis-3.2.1]# ls
00-RELEASENOTES BUGS CONTRIBUTING COPYING deps INSTALL Makefile MANIFESTO README.md redis.conf runtest runtest-cluster runtest-sentinel sentinel.conf src tests utils
make需要安装编译器,默认为gcc.
[[email protected] redis-3.2.1]# make
cd src && make all

Hint: It‘s a good idea to run ‘make test‘ ;)
make[1]: Leaving directory `/root/redis/redis-3.2.1/src‘
make完成之后,进行install,默认安装路径为/usr/local/bin下,这里我们把他安装目录放到/usr/local/redis下,使用PREFIX指定目录:
[[email protected] redis-3.2.1]# mkdir /usr/local/redis
[[email protected] redis-3.2.1]# make PREFIX=/usr/local/redis install
cd src && make install
make[1]: Entering directory `/root/redis/redis-3.2.1/src‘
Hint: It‘s a good idea to run ‘make test‘ ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
make[1]: Leaving directory `/root/redis/redis-3.2.1/src‘
将redis可执行目录添加到环境变量中,编辑~/.bash_profile添加redis环境变量:
[[email protected] bin]# cat ~/.bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=/usr/local/redis/bin:/usr/local/mongodb/bin:$PATH:$HOME/bin
3.创建redis服务
此时其实就可以启动redis服务了,例如:
% ./redis-server --port 9999 --slaveof 127.0.0.1 6379
% ./redis-server /etc/redis/6379.conf --loglevel debug
但是我们一般还是把redis做成服务来启动,进入到utils目录,然后运行install_server.sh,运行这个会询问你几个问题,包括
指定redis的端口号
指定redis的配置文件
指定redis的日志文件
指定redis的数据目录文件
指定redis的可执行目录文件.
[[email protected] utils]# ./install_server.sh
Welcome to the redis service installer
This script will help you easily set up a running redis server
Please select the redis port for this instance: [6379]
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf]
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log] /data/redis/log/redis_6378.log
Please select the data directory for this instance [/var/lib/redis/6379] /data/redis/6379
Please select the redis executable path [/usr/local/redis/bin/redis-server]
Selected config:
Port : 6379
Config file : /etc/redis/6379.conf
Log file : /data/redis/log/redis_6378.log
Data dir : /data/redis/6379
Executable : /usr/local/redis/bin/redis-server
Cli Executable : /usr/local/redis/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379
Installing service...
Successfully added to chkconfig!
Successfully added to runlevels 345!
Starting Redis server...
Installation successful!
完成之后,redis的服务就添加完毕了,服务名为redis_6379:
[[email protected] init.d]# ls -l re*
-rwxr-xr-x 1 root root 1714 Jul 1 11:13 redis_6379
-rwxr-xr-x. 1 root root 1822 Jan 16 2013 restorecond
启动和关闭redis服务:
[[email protected] init.d]# service redis_6379 status
Redis is running (19280)
[[email protected] init.d]# service redis_6379 stop
Stopping ...
Redis stopped
[[email protected] init.d]# service redis_6379 start
Starting Redis server...
使用redis-cli连接redis:
[[email protected] init.d]# redis-cli
127.0.0.1:6379>
4.redis服务解析
其实做完以上几步,我们已经可以正常使用redis了,下面我们来解析一下redis的启动停止过程.我们解析/etc/init.d/redis_6379文件:
#!/bin/sh
#Configurations injected by install_server below....
EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
PIDFILE=/var/run/redis_6379.pid
CONF="/etc/redis/6379.conf"
REDISPORT="6379"
###############
# SysV Init Information

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
;;
status)
PID=$(cat $PIDFILE)
if [ ! -x /proc/${PID} ]
then
echo ‘Redis is not running‘
else
echo "Redis is running ($PID)"
fi
;;
restart)
$0 stop
$0 start
;;
*)
echo "Please use start, stop, restart or status as first argument"
;;
esac
可以发现,其实启动redis的语法就是:
/usr/local/redis/bin/redis-server /etc/redis/6379.conf
关闭redis的语法就是:
/usr/local/redis/bin/redis-server -p 6379 shutdown
检查redis是否运行,就是检查redis的pid文件下的进程是否存在.
查看redis的配置文件/etc/redis/6379.conf,里面有很多注释,去除注释:
[[email protected] utils]# grep -E -v "^#" /etc/redis/6379.conf |sed ‘/^$/d‘

bind:绑定的ip地址

pidfile:pid文件名
dir:数据文件目录
logfile:日志文件地址
最后我分享一下我遇到的坑：
第一：我发现别的服务器不可以访问redis
开始以为是iptables 然后各种设置不中
程序连接 connection timetout 本地telnet也不通 原因是 etc/redis/6379.conf 里面bind 127.0.0.1 把所有的bind去掉 这样就可以任意访问了 不用设置具体的ip。
第二：第一步设置完之后 用程序连接发现报如下错误：
redis.clients.jedis.exceptions.JedisDataException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only
accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command ‘CONFIG SET protected-mode no‘ from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to ‘no‘, and then restarting the server. 3) If you started the server manually just for testing, restart it with the ‘--protected-mode no‘ option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.
at redis.clients.jedis.Protoc
大致意思是开启了保护模式 访问只能通过backloop地址访问
解决办法依旧是修改7379_conf 把protected-mode 修改为no 然后 daemonize no设置为yes 注册为服务在后台跑
重新启动redis就ok
