• redis安装(单节点)


    # tar -zxvf redis.tar.gz

    # cd redis

    安装(使用 PREFIX 指定安装目录):

    # make PREFIX=/usr/local/redis install

    安装完成后,可以看到/usr/local/redis 目录下有一个 bin 目录,bin 目录里就是 redis 的命令脚本: redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server

    Redis 配置成服务:

    按上面的操作步骤,Redis 的启动脚本为:/usr/local/src/redis/utils/redis_init_script

    将启动脚本复制到/etc/rc.d/init.d/目录下,并命名为 redis:

    # cp /usr/local/src/redis/utils/redis_init_script /etc/rc.d/init.d/redis

    编辑/etc/rc.d/init.d/redis,修改相应配置,使之能注册成为服务:

    # vi /etc/rc.d/init.d/redis #!/bin/sh

    # Simple Redis init.d script conceived to work on Linux systems

    # as it does use of the /proc filesystem.

    REDISPORT=6379

    EXEC=/usr/local/bin/redis-server

    CLIEXEC=/usr/local/bin/redis-cli

    PIDFILE=/var/run/redis_${REDISPORT}.pid

    CONF="/etc/redis/${REDISPORT}.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

    查看以上 redis 服务脚本,关注标为橙色的几个属性,做如下几个修改的准备:

    (1) 在脚本的第一行后面添加一行内容如下:

    #chkconfig: 2345 80 90

    (如果不添加上面的内容,在注册服务时会提示:service redis does not support chkconfig)

    (2) REDISPORT 端口保持 6379 不变;(注意,端口名将与下面的配置文件名有关)

    (3) EXEC=/usr/local/bin/redis-server 改为 EXEC=/usr/local/redis/bin/redis-server

    (4) CLIEXEC=/usr/local/bin/redis-cli 改为 CLIEXEC=/usr/local/redis/bin/redis-cli

    (5) 配置文件设置:

    创建 redis 配置文件目录

    # mkdir /usr/local/redis/conf

    复制 redis 配置文件/usr/local/src/redis/redis.conf /usr/local/redis/conf 目录并按端口

    号重命名为 6379.conf

    # cp /usr/local/src/redis/redis.conf /usr/local/redis/conf/6379.conf

    做了以上准备后,再对 CONF 属性作如下调整:

    CONF="/etc/redis/${REDISPORT}.conf" 改为 CONF="/usr/local/redis/conf/${REDISPORT}.conf"

    (6) 更改 redis 开启的命令,以后台运行的方式执行: $EXEC $CONF & #“&”作用是将服务转到后面运行

    修改后的/etc/rc.d/init.d/redis 服务脚本内容为:

    #!/bin/sh

    #chkconfig: 2345 80 90

    #

    # Simple Redis init.d script conceived to work on Linux systems

    # as it does use of the /proc filesystem.

    REDISPORT=6379

    EXEC=/usr/local/redis/bin/redis-server

    CLIEXEC=/usr/local/redis/bin/redis-cli

    PIDFILE=/var/run/redis_${REDISPORT}.pid

    CONF="/usr/local/redis/conf/${REDISPORT}.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

    以上配置操作完成后,便可将 Redis 注册成为服务:

    # chkconfig --add redis

    防火墙中打开对应的端口

    # vi /etc/sysconfig/iptables

    添加:

    -A INPUT -m state --state NEW -m tcp -p tcp --dport 6379 -j ACCEPT

    重启防火墙:

    # service iptables restart

    修改 redis 配置文件设置:

    # vi /usr/local/redis/conf/6379.conf

    修改如下配置

    daemonize no 改为> daemonize yes

    pidfile /var/run/redis.pid 改为> pidfile /var/run/redis_6379.pid

    启动 Redis 服务

    # service redis start

    Redis 添加到环境变量中:

    # vi /etc/profile

    在最后添加以下内容:

    ## Redis env

    export PATH=$PATH:/usr/local/redis/bin

    使配置生效:

    # source /etc/profile

    现在就可以直接使用 redis-cli  redis 命令了:

    关闭 Redis 服务

    # service redis stop

    默认情况下,Redis 开启安全认证,可以通过/usr/local/redis/conf/6379.conf  requirepass 指定一个

    验证密码。
