###刷新 systemctl
systemctl daemon-reload
编写关闭脚本
vim /data/redis/bin/redis-shutdown
#!/bin/bash
#
# Wrapper to close properly redis and sentinel 包装关闭正确的redis和哨兵
test x"$REDIS_DEBUG" != x && set -x
REDIS_CLI=/data/redis/bin/redis-cli
# Retrieve service name 检索服务名称
SERVICE_NAME="$1"
if [ -z "$SERVICE_NAME" ]; then
SERVICE_NAME=redis
fi
# Get the proper config file based on service name 根据服务名称获取适当的配置文件
CONFIG_FILE="/etc/redis/$SERVICE_NAME.conf"
# Use awk to retrieve host, port from config file 使用awk从配置文件中检索主机，端口
HOST=`awk '/^[[:blank:]]*bind/ { print $2 }' $CONFIG_FILE | tail -n1`
PORT=`awk '/^[[:blank:]]*port/ { print $2 }' $CONFIG_FILE | tail -n1`

SOCK=`awk '/^[[:blank:]]*unixsocket\s/ { print $2 }' $CONFIG_FILE | tail -n1`
# Just in case, use default host, port 以防万一，使用默认的主机和端口
HOST=${HOST:-127.0.0.1}
if [ "$SERVICE_NAME" = redis ]; then
PORT=${PORT:-6379}
else
PORT=${PORT:-26739}
fi
# Setup additional parameters 其他参数设置
# e.g password-protected redis instances 例如密码保护的redis实例
[ -z "$PASS" ] || ADDITIONAL_PARAMS="-a $PASS"
# shutdown the service properly 正确关闭服务
if [ -e "$SOCK" ] ; then
$REDIS_CLI -s $SOCK $ADDITIONAL_PARAMS shutdown
else
$REDIS_CLI -h $HOST -p $PORT $ADDITIONAL_PARAMS shutdown
fi
创建redis用户和数据目录
useradd -r -s /sbin/nologin redis
###设置目录权限
chown -R redis.redis /app/redis/
redis防火墙设置
firewall-cmd --permanent --zone=public --add-port=6379/tcp
firewall-cmd --reload
firewall-cmd --list-all
启动
###前台启动redis
redis-server /app/redis/etc/redis.conf
###开启redis多范例
redis-server --port 6380
redis-server --port 6379
ps -ef | grep redis
###systemctl启动
systemctl start redis
systemctl status redis
systemctl enable redis
优化
cat >> /etc/sysctl.conf <cat >> /etc/sysctl.conf <解决透明大页，可能导致redis延迟和内存使用问题
echo 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' >> /etc/rc.local
