    Centos7安装redis

    Yum安装

    yum install epel-release
    yum install redis
    

    常用命令

    #启动
    systemctl start redis.service
    #重启  
    systemctl restart redis.service
    #关闭  
    systemctl stop redis.service
    
    

    配置文件

    /etc/redis.conf

    源码编译安装

    说明:自 redis 6.0.0 之后,编译 redis 需要支持 C11 特性。Centos7 默认 gcc 版本为 4.8.5C11 特性在 4.9 中引入

    yum install gcc gcc-c++

    • 需要gcc高版本的解决方案

      解决方案

      安装 Developer Toolset 7 使用 gcc 7 编译

      yum install centos-release-scl scl-utils-build #安装scl工具
      yum install devtoolset-7-gcc.x86_64 devtoolset-7-gcc-c++.x86_64 devtoolset-7-gcc-gdb-plugin.x86_64  #安装gcc7
      scl -l  #查看安装的版本
      scl enable devtoolset-7 bash  #切换版本  使用exit 退出当前scl版本的bash环境
      

    使用稳定版

    wget http://download.redis.io/releases/redis-6.0.5.tar.gz

    image-20200625112935175

    tar -zxvf redis-6.0.5.tar.gz -C /opt
    cd /opt/redis-6.0.5
    make test  #出现 All tests passed without errors!
    make && make install
    

    配置开机自启动

    编写redis.conf配置文件

    配置文件路径:/etc/redis.conf

    daemonize是守护进程的意思

    把daemonize no改成daemonize yes

    新建个redis启动脚本

    注意要修改里面redis的安装路径:我这边的安装路径是/usr/local/redis/

    这段代码就是redis根目录 /utils/redis_init_script 启动脚本的代码

    我这边是用了install_server.sh自动生成的,所以不用改那么多东西,直接用就行

    直接chmod + x /etc/init.d/redis

    然后systemctl start redis_6379就可以启动了

    #!/bin/sh
    #Configurations injected by install_server below....
    
    EXEC=/usr/local/redis/src/redis-server
    CLIEXEC=/usr/local/redis/src/redis-cli
    PIDFILE=/var/run/redis_6379.pid
    CONF="/etc/redis/6379.conf"
    REDISPORT="6379"
    ###############
    # SysV Init Information
    # chkconfig: - 58 74

    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
    

    配置密码和远程访问

    远程访问

    在配置文件/etc/redis.conf中方的61行左右

    image-20200625115124912

    配置密码

    在配置文件/etc/redis.conf的480行左右,找到# requirepass foobared在其下面加上一行,加上一行requirepass 123456 设置密码为123456

    image-20200625114849911

    注意!!!

    远程连接一定要开放防火墙的端口,或者直接关闭防火墙(不建议)

    # 开放6379端口
    firewall-cmd --permanent --add-port=6379/tcp
    #重新加载配置
    firewall-cmd --reload
    

    有可能遇到的问题

    You need tcl 8.5 or newer in order to run the Redis test

    解决方式

    1、安装tcl

    yum install tcl
