redis 的介绍

Redis是一种高级key-value数据库。它跟memcached类似,不过数据可以持久化,而且支持的数据类型很丰富。有字符串,链表,集 合和有序集合。支持在服务器端计算集合的并,交和补集(difference)等,还支持多种排序功能。所以Redis也可以被看成是一个数据结构服务器。 PS:此次安装为redis储存字符串的形式,储存用户会话session。

Redis 的安装

redis的准备工作,安装依赖包

Centos系列:

yum repolist
yum -y install gcc gcc-c++ make gmake cmake zlib  tcl
Copy after login

Ubuntu系列:

agt-get update
Agt-get install gcc gcc-c++ make zlib tcl
Copy after login

下载包,安装redis

cd /usr/local/src                        \\进入软件包目录(规范化)
wget http://download.redis.io/releases/redis-3.2.9.tar.gz
                                    \\下载软件包
tar -xzf redis-3.2.9.tar.gz          \\#解压并进入redis目录cd redis-3.2.9                       \\解压并进入redis目录#运行测试./runtest#预编译  编译安装make
make test#进入src目录安装cd src
make PREFIX=/usr/local/redis install
PS:redis的编译安装过程漫长,在此处我们把redis编译安装到了"/usr/local/redis"目录了,默认情况下bin命令都是在"/usr/bin"下面直接可以调用redis的命令。指的安装路径后我们需要在后期添加系统环境变量。

Redis配置文件

创建redis的配置文件目录,拷贝配置文件redis.conf

mkdir -p /usr/local/redis/etc
cp /usr/local/src/redis-3.2.9/redis.conf /usr/local/redis/etc/redis.conf
Copy after login

修改配置文件

vim /usr/local/redis/etc/redis.conf cat /usr/local/redis/etc/redis.conf |grep -v “^$” |grep -v “#

How to configure single instance redis in Linux PS:注意配置日志和pid等的位置,要和启动脚本关联。密码也要和启动脚本关联。

创建修改系统启动配置文件

创建系统服务启动文件

启动文件的模板:/usr/local/src/redis-3.2.9/utils/redis_init_script

cp /usr/local/src/redis-3.2.9/utils/redis_init_script /etc/init.d/redis
chmod 755 /etc/init.d/redis
Copy after login

修改系统启动脚本

#!/bin/sh#Configurations injected by install_server below....EXEC=/usr/local/redis/bin/redis-server  ######服务命令启动#####CLIEXEC=/usr/local/redis/bin/redis-cli  ####客户端命令路径###PIDFILE=/var/run/redis.pid  ###pid文件所在位置#####要和配置文件一致CONF="/usr/local/redis/etc/redis.conf"  ####redis配置文件的路径##REDISPORT="6379"    #####启动端口##################### SysV Init Information# chkconfig: - 58 74   #####添加内容,注释但有意义####### description: redis_6379 is the redis daemon.### BEGIN INIT INFO# Provides: redis_6379  #####启动端口##################### Required-Start: $network $local_fs $remote_fs# Required-Stop: $network $local_fs $remote_fs# Default-Start: 2 3 4 5# Default-Stop: 0 1 6# Should-Start: $syslog $named# Should-Stop: $syslog $named# Short-Description: start and stop redis_6379# Description: Redis daemon### END 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 $REDISPORT -a mima shutdown \\###修改内容,添加-a密码验证的项目###while [ -x /proc/${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
Copy after login

PS:看过《Linux就该这样学》的人都知道系统启动文件怎么写,什么格式,在这里我们就不在解释了。

redis 启动脚本添加认证两个方法

方法一: How to configure single instance redis in Linux 方法二: How to configure single instance redis in Linux

将启动脚本添加到系统服务

chkconfig --add redis    #添加系统服务chkconfig redis on           #设置开机自启service redis start
service redis status
service redis stop
service redis restart
Copy after login

Ubuntu系统没有chkconfig

PS:chkconfig 在ubuntu系统中有可能不太容易安装,可以使用update-rc.d 命令来进行使用。

update-rc.d redisd defaults 80 80

root@linuxprobe:/etc/redis# update-rc.d redisd defaults 80 80Adding system startup for /etc/init.d/redisd ...
/etc/rc0.d/K80redisd -> ../init.d/redisd
/etc/rc1.d/K80redisd -> ../init.d/redisd
/etc/rc6.d/K80redisd -> ../init.d/redisd
/etc/rc2.d/S80redisd -> ../init.d/redisd
/etc/rc3.d/S80redisd -> ../init.d/redisd
/etc/rc4.d/S80redisd -> ../init.d/redisd
/etc/rc5.d/S80redisd -> ../init.d/redisd
  2345 启动    0 1 6 关闭

如果在启动脚本里没有添加认证字段:
