初始准备

本次安装基于 Centos7

创建redis用户

groupadd redis
useradd -g redis redis -s /sbin/nologin -M

创建redis相关目录

#数据目录
mkdir -pv /data/redis
chown -R redis:redis /data/redis

#日志目录
mkdir -pv /data/logs/redis
chown -R redis:redis /data/logs/redis

#redis目录
mkdir -pv /usr/local/redis/{bin,etc}

编译安装

#安装依赖
yum install clang -y

cd /data/packages
#下载
wget http://download.redis.io/releases/redis-6.2.6.tar.gz

#解压
tar -zxvf redis-6.2.6.tar.gz

#编译安装
cd redis-6.2.6 && CC=clang make
#报错就 make MALLOC=libc
install -p -D -m 0755 src/redis-benchmark /usr/local/redis/bin/
install -p -D -m 0755 src/redis-check-aof /usr/local/redis/bin/
install -p -D -m 0755 src/redis-check-rdb /usr/local/redis/bin/
install -p -D -m 0755 src/redis-cli /usr/local/redis/bin/
install -p -D -m 0755 src/redis-sentinel /usr/local/redis/bin/
install -p -D -m 0755 src/redis-server /usr/local/redis/bin/
install -p -D -o redis redis.conf /usr/local/redis/etc/
ln -svf /usr/local/redis/bin/redis-cli /usr/bin/redis-cli

配置相关

修改配置文件

#修改配置文件
export REDIS_HOME=/usr/local/redis
sed -i s@'^logfile .*'@"logfile /data/logs/redis/redis.log"@ $REDIS_HOME/etc/redis.conf
sed -i s@'^dir .*'@"dir /data/redis"@ $REDIS_HOME/etc/redis.conf
sed -i s@'^pidfile .*'@"pidfile /data/redis/redis_6379.pid"@ $REDIS_HOME/etc/redis.conf
sed -i s@'^bind .*'@"bind 0.0.0.0"@ $REDIS_HOME/etc/redis.conf

配置 shutdown脚本 脚本

#创建redis-shutdown脚本
vim /usr/local/redis/bin/redis-shutdown
#!/bin/bash
test x"$REDIS_DEBUG" != x && set -x

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

SERVICE_NAME="$1"
if [ -z "$SERVICE_NAME" ]; then
   SERVICE_NAME=redis
fi

CONFIG_FILE="/usr/local/redis/etc/$SERVICE_NAME.conf"

HOST=`awk '/^[[:blank:]]*bind/ { print $2 }' $CONFIG_FILE | tail -n1`
PORT=`awk '/^[[:blank:]]*port/ { print $2 }' $CONFIG_FILE | tail -n1`
PASS=`awk '/^[[:blank:]]*requirepass/ { print $2 }' $CONFIG_FILE | tail -n1`
SOCK=`awk '/^[[:blank:]]*unixsocket\s/ { print $2 }' $CONFIG_FILE | tail -n1`

HOST=${HOST:-127.0.0.1}
if [ "$SERVICE_NAME" = redis ]; then
    PORT=${PORT:-6379}
else
    PORT=${PORT:-26739}
fi

[ -z "$PASS"  ] || ADDITIONAL_PARAMS="-a $PASS"

if [ -e "$SOCK" ] ; then
        $REDIS_CLI -s $SOCK $ADDITIONAL_PARAMS shutdown
else
        $REDIS_CLI -h $HOST -p $PORT $ADDITIONAL_PARAMS shutdown
fi
chmod +x /usr/local/redis/bin/redis-shutdown

创建 Systemd 配置
