linux上安装redis

1.首先下载依赖,譬如jdk,tomcat,mysql安装过程需要下载部分支持包,redis是c语言编写,所以依赖c++

yum install glibc.i686
    
    yum -y install libaio.so.1 libgcc_s.so.1 libstdc++.so.6
    
    yum update libstdc++-4.4.7-4.e16.x86_64
    
    yum install gcc-c++

2.上传redis压缩包,并解压

tar -zxvf redis-3.2.12.tar.gz

3.进入到解压后的目录,进行编译,因为redis是有c++编写,所以需要make命令

make

4.安装

make PREFIX=/usr/local/redis install

5.进入到解压位置,复制redis.conf到安装位置

cp redis.conf /usr/local/redis

6.进入到安装位置,修改redis.conf配置文件,允许后端启动,方便配置集群服务

vim redis.conf
    //打开配置文件
    //修改以下语句
    daemonize no修改为daemonize yes

7.启动redis

./bin/redis-server ./redis.conf

8.查看redis启动

ps -ef | grep -i redis

9.关闭

第一种方式: 查询pid，kill -9 进程号（容易数据丢失）
    第二种方式: 正常关闭：./bin/redis-cli shutdown

10.开机自启

1.编写开机自启脚本
      vi /etc/init.d/redis
    2.脚本代码如下
      
    
    #!/bin/sh
    #
    # Simple Redis init.d script conceived to work on Linux systems
    # as it does use of the /proc filesystem.
    # chkconfig: 2345 90 10
    # description: Redis is a per....
    REDISPORT=7000
    EXEC=/home/zjk/redis/bin/redis-server
    CLIEXEC=/home/zjk/redis/bin/redis-cli
    
    PIDFILE=/var/run/redis_7000.pid
    CONF="/home/zjk/redis/redis-7000.conf"
    
    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
            ;;
        *)
            echo "Please use start or stop as first argument"
            ;;
    esac
    3.修改文件权限
      chmod 755 /etc/init.d/redis
    4.开机服务自启
      chkconfig redis on
