linux下安装redis3.2

这部分来自网络：

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:

[root@mongodb1 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:

[root@mongodb1 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.

[root@mongodb1 redis-3.2.1]# make

cd src && make all

make[1]: Entering directory `/root/redis/redis-3.2.1/src'

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:

[root@mongodb1 redis-3.2.1]# mkdir /usr/local/redis

[root@mongodb1 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'

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:

[root@mongodb1 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.

[root@mongodb1 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:

[root@mongodb1 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:

[root@mongodb1 init.d]# service redis_6379 status

Redis is running (19280)

[root@mongodb1 init.d]# service redis_6379 stop

Stopping ...

Redis stopped

[root@mongodb1 init.d]# service redis_6379 start

Starting Redis server...

使用redis-cli连接redis:

[root@mongodb1 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

# chkconfig: - 58 74

# description: redis_6379 is the redis daemon.

### BEGIN INIT INFO

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:

[root@mongodb1 utils]# grep -E -v "^#" /etc/redis/6379.conf |sed '/^$/d'

其中主要的参数:

bind:绑定的ip地址

pidfile:pid文件名

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
