CentOS 7编译安装Redis

安装编译相关依赖

CentOS/Fedora

yum install gcc gcc-c++ cmake tcl

下载Redis源码包

curl -o redis-4.0.10.tar.gz http://download.redis.io/releases/redis-4.0.10.tar.gz

解压Redis源码包

tar -xzvf redis-4.0.10.tar.gz

编译

具体过程:

# 进入解压目录, 默认在当前目录

cd redis-4.0.10

# 执行make

make

# 安装, 指定目录

make PREFIX=/usr/local/redis install

Redis配置

# 将配置文件放在/usr/local/redis/etc/下面, 放在/etc/redis/下也可以

mkdir /usr/local/redis/etc/

# 将解压目录中的redis.conf拷贝到/usr/local/redis/etc/下面

cp redis.conf /usr/local/redis/etc/

# 进入redis的执行文件目录

cd /usr/local/redis/bin/

# 将redis-benchmark, redis-cli, redis-server复制到/usr/bin

cp redis-benchmark redis-cli redis-server /usr/bin/

调整内存分配使用方式, 并使其生效:

# 此参数可用的值为0,1,2

# 0.表示当用户空间请求更多的内存时，内核尝试估算出可用的内存

# 1.表示内核允许超量使用内存直到内存用完为止

# 2.表示整个内存地址空间不能超过swap+(vm.overcommit_ratio)%的RAM值 

echo "vm.overcommit_memory=1" >> /etc/sysctl.conf

sysctl -p

修改Redis配置和Redis加固

Redis配置

编辑配置文件vim /usr/local/redis/etc/redis.conf, 将其中的对应内容修改为:

# redis以守护进程的方式运行, no表示不以守护进程的方式运行(会占用一个终端)

daemonize yes

# 密码

requirepass password

# 绑定ip

# bind 127.0.0.1

# 端口

port 7480

# 数据目录

dir /data/redis

# 客户端闲置多长时间后断开连接，默认为0关闭此功能

timeout 300

# 设置redis日志级别，默认级别：notice

loglevel verbose

# 设置日志文件的输出方式,如果以守护进程的方式运行redis 默认:""

# 并且日志输出设置为stdout,那么日志信息就输出到/dev/null里面去了

logfile stdout

Redis加固

绑定127.0.0.1

如果只是本地通信, 就确保监听在本地, 修改配置文件的bind 127.0.0.1
设置防火墙

如果需要其他机器访问，或者设置了slave模式，那就记得加上相应的防火墙设置，命令如下:

iptables -A INPUT -s x.x.x.x -p tcp --dport 6379 -j ACCEPT
认证

添加密码, 修改配置文件requirepass asdlkashdkj123123
低权限账户

创建一个redis用户, 使用这个用户执行redis-server

useradd -M -s /sbin/nologin redis

setsid sudo -u redis /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf'

Redis启动脚本

CentOS 6的service服务

cp /root/redis-4.0.10/utils/redis_init_script  /etc/rc.d/init.d/redis

在文件的开头#!的下一行添加vim /etc/rc.d/init.d/redis:

# chkconfig: 2345 90 10

# description: Redis is a persistent key-value database

如果添加了密码, 请添加-a password在$CLIEXEC -a password -p $REDISPORT shutdown中.

再在stop的;;后添加:

restart)

    $0 stop

    $0 start

    ;;

status)

    PID=$(cat $PIDFILE)

    if [ ! -x /proc/${PID} ]

    then

        echo 'Redis is not running'

    else

        echo "Redis is running ($PID)"

    fi

    ;;

例如:

#!/bin/sh

#

# chkconfig: 2345 90 10

# description: Redis is a persistent key-value database

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

# as it does use of the /proc filesystem.

    start)

        if [ -f $PIDFILE ]

                echo "$PIDFILE exists, Process is already running or crashed"

        else

                echo "Starting Redis server..."

                $EXEC $CONF

                printf "Redis \033[1;32;32mStarted...\033[0m\n"

                    sleep 1

                done

                printf "Redis \033[1;32;32mStopped...\033[0m\n"

        then

            echo "$PIDFILE does not exist, Process is not running"

            exit 6379

        fi

        PID=$(cat $PIDFILE)

        if [ ! -x /proc/${PID} ]

        then

            printf "Redis is \033[1;31;31mnot running\033[0m\n"

    *)

        echo "Please use start or stop as first argument"

        ;;

# 如果没报错的话，说明成功，可以用

chkconfig --add redis

# 启动redis服务器

service redis start

# 开机自启

chkconfig redis on

# 查看是否启动成功

ps -ef | grep redis

CentOS 7的systemd服务

在/usr/lib/systemd/system目录下创建redis.service文件, 权限为root.root 755, 输入以下内容, 将ExecStart后面的执行路径修改为自己的路径:

[Unit]

Description=Redis persistent key-value database

After=network.target

[Service]

ExecStart=/usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf --daemonize yes

ExecStop=/usr/local/redis/bin/redis-cli -a password -p 6379 shutdown

User=redis

Group=redis

RuntimeDirectory=redis

RuntimeDirectoryMode=0755

[Install]

WantedBy=multi-user.target

然后创建/usr/libexec/redis-shutdown文件, 输入以下内容, 记得将REDIS_CLI和CONFIG_FILE修改为自己的路径:

#!/bin/bash

#

# Wrapper to close properly redis and sentinel

test x"$REDIS_DEBUG" != x && set -x

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

# Retrieve service name

SERVICE_NAME="$1"

if [ -z "$SERVICE_NAME" ]; then

   SERVICE_NAME=redis

fi

# Get the proper config file based on service name

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

# Use awk to retrieve host, port from config file

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`

# Just in case, use default host, port

HOST=${HOST:-127.0.0.1}

if [ "$SERVICE_NAME" = redis ]; then

    PORT=${PORT:-6379}

else

    PORT=${PORT:-26739}

fi

# Setup additional parameters

# e.g password-protected redis instances

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

# shutdown the service properly

if [ -e "$SOCK" ] ; then

    $REDIS_CLI -s $SOCK $ADDITIONAL_PARAMS shutdown

else

    $REDIS_CLI -h $HOST -p $PORT $ADDITIONAL_PARAMS shutdown

fi

修改/usr/libexec/redis-shutdown权限, chmod 755 /usr/libexec/redis-shutdown

重新载入systemd, 扫描新的或有变动的service, systemctl daemon-reload

开机自启, systemctl enable redis
