环境说明

CentOS Linux release 7.9.2009 (Core）环境下源码编译安装redis

1 下载

#wget https://download.redis.io/releases/redis-6.2.6.tar.gz
tar -xzf redis-6.2.6.tar.gz
cd redis redis-6.2.6

2 编译

yum -y install gcc gcc-c++ kernel-devel
make

3 安装

make PREFIX=/usr/local/redis install
mkdir /usr/local/redis/etc/
cp redis.conf /usr/local/redis/etc/
cd /usr/local/redis/bin/
cp redis-benchmark redis-cli redis-server /usr/bin/

4 更改配置

vim /usr/local/redis/etc/redis.conf

# 修改一下配置
# 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

# 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
# 设置密码授权
requirepass <设置密码>
# 监听ip
bind 0.0.0.0 

5 配置环境变量

vim /etc/profile
export PATH="$PATH:/usr/local/redis/bin"
# 保存退出

# 让环境变量立即生效
source /etc/profile

6 配置启动脚本

#!/bin/bash
#chkconfig: 2345 80 90
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
EXEC=/usr/local/redis/bin/redis-server
REDIS_CLI=/usr/local/redis/bin/redis-cli
   
PIDFILE=/var/run/redis.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 "Starting Redis server..."
                $EXEC $CONF
        fi
        if [ "$?"="0" ] 
        then
              echo "Redis is running..."
        fi
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $REDIS_CLI -p $REDISPORT SHUTDOWN
                while [ -x ${PIDFILE} ]
               do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
   restart|force-reload)
        ${0} stop
        ${0} start
        ;;
  *)
    echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
        exit 1
esac

7 开机自启动

# 复制脚本文件到init.d目录下
cp redis /etc/init.d/

# 给脚本增加运行权限
chmod +x /etc/init.d/redis

# 查看服务列表
chkconfig --list

# 添加服务
chkconfig --add redis

# 配置启动级别
chkconfig --level 2345 redis on

8 启动测试

systemctl start redis   #或者 /etc/init.d/redis start  
systemctl stop redis   #或者 /etc/init.d/redis stop

# 查看redis进程
ps -el|grep redis

# 端口查看
netstat -an|grep 6379
