Centos7 安装Redis数据库

一、安装redis

# 安装wget
yum install -y wget
# 创建并进入目录
mkdir /home/softs && cd /home/softs
# 下载redis 5.0.8版本
wget http://download.redis.io/releases/redis-5.0.8.tar.gz
# 解压
tar -xzvf redis-5.0.8.tar.gz
# 进入redis目录
cd redis-5.0.8
# 安装依赖
yum -y install gcc gcc-c++
# 执行编译安装  目录/usr/local/redis
make PREFIX=/usr/local/redis install
# 创建配置文件目录
mkdir -p /usr/local/redis/etc/
# 复制默认配置文件到目录
cp redis.conf  /usr/local/redis/etc/
# 编辑配置文件
vi /usr/local/redis/etc/redis.conf

/usr/local/redis/etc/redis.conf文件修改以下几行

# 取消IP绑定
bind 127.0.0.1   =>   # bind 127.0.0.1
# 关闭保护模式
protected-mode yes   =>   protected-mode no
# 修改端口
port 6379
# 开启后台守护模式
daemonize no   =>   daemonize yes
# 设置远程密码
requirepass foobared   =>   requirepass 密码

二、创建启动脚本

# 创建init.d文件
vi /etc/init.d/redis

init.d文件内容：

#! /bin/bash
#   
# redis - this script starts and stops the redis-server daemon
#   
# chkconfig:    2345 80 90
# description:  Redis is a persistent key-value database
#   
### BEGIN INIT INFO

# Required-Start:    $syslog
# Required-Stop:     $syslog
# Should-Start:        $local_fs
# Should-Stop:        $local_fs
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description:    redis-server daemon

### END INIT INFO

REDISPORT=8005
EXEC=/usr/local/redis/bin/redis-server
REDIS_CLI=/usr/local/redis/bin/redis-cli
   
PIDFILE=/var/run/redis_6379.pid
CONF="/usr/local/redis/etc/redis.conf"
   
case "$1" in
    start)
        if [ -f "$PIDFILE" ]; then
            echo "$PIDFILE exists, process is already running or crashed"
        else
            echo -n "Starting Redis server..."
            $EXEC $CONF
            if [ "$?"="0" ]; then
                echo " done"
            else
                echo " failed"
            fi
        fi
        ;;
    stop)
        if [ ! -f "$PIDFILE" ]; then
            echo "$PIDFILE does not exist, process is not running"
        else
            PID=$(cat $PIDFILE)
            echo "Stopping  Redis server..."
            $REDIS_CLI -p $REDISPORT shutdown
            if [ "$?"="0" ]; then
                echo " done"
            else
                echo " failed"
            fi
        fi
        ;;
    restart)
        ${0} stop
        ${0} start
        ;;
    kill)
        echo "force kill redis server..."
        killall redis-server
        if [ "$?"="0" ]; then
            echo " done"
        else
            echo " failed"
        fi
        ;;
    status)
        if [ -f "$PIDFILE" ]; then
            echo "Redis server is running."
        else
            echo "Redis server is stopped."
        fi
        ;;
  *)
    echo "Usage: /etc/init.d/redis {start|stop|restart|status|kill}" >&2
        exit 1
esac

# 修改权限
chmod +x /etc/init.d/redis
# 启动
/etc/init.d/redis start
# 设置开机自动启动
chkconfig redis on

三、设置防火墙

# 启动服务
systemctl start firewalld.service
# 放行端口
firewall-cmd --zone=public --add-port=6379/tcp --permanent
# 重载配置
firewall-cmd --reload
# 查看配置
firewall-cmd --list-all
# 开启自动启动
systemctl enable firewalld.service
