一、搭建初始環境

安裝支持的庫文件

$ sudo yum install -y wget vim net-tools lrzsz make gcc automake libtool
#automake中包含autoconf包

安裝tcl【make test時需要】

$ rpm -qa|grep tcl
$ sudo yum -y install tcl
  已安裝:
    tcl-1:8.6.8-2.el8.x86_64

二、安裝

提取和編譯redis

$ sudo wget http://download.redis.io/releases/redis-5.0.8.tar.gz
或者
$ curl -O http://download.redis.io/releases/redis-5.0.8.tar.gz
$ tar xzf redis-5.0.8.tar.gz 
$ cd redis-5.0.8
$ make MALLOC=libc
$ sudo make install

make install後出現以下文件

 redis-server
 redis-sentinel
 redis-cli
 redis-benchmark
 redis-check-rdb
 redis-check-aof

清除make編譯結果【如果make出錯可以使用此命令】

$ make clean

啓動redis；src 目錄中現在提供了已編譯的二進制文件

$ ./src/redis-server

您可以使用內置的客戶端與Redis進行互動：

$ ./src/redis-cli 
127.0.0.1:6379> set foo bar
OK
127.0.0.1:6379> get foo
"bar"
127.0.0.1:6379> ping
PONG

三、配置啓動腳本【測試發現centos8.0中該方法中的開機自啓失效了】

查看路徑與/home/long/redis-5.0.8/utils/redis_init_script文件中路徑一致
$ sudo find / -name redis-server
/home/long/redis-5.0.8/src/redis-server
/usr/local/bin/redis-server
$ sudo find / -name redis-cli
/home/long/redis-5.0.8/src/redis-cli
/usr/local/bin/redis-cli

$ sudo ln -s /home/long/redis-5.0.8/utils/redis_init_script /etc/init.d/redisd

需要配置的參數
$ sudo vim /home/long/redis-5.0.8/utils/redis_init_script
  18 PIDFILE=/var/run/redis_${REDISPORT}.pid
  19 CONF="/etc/redis/${REDISPORT}.conf"
改爲
  18 PIDFILE=/var/run/redis_6379.pid #此處的名字必須與配置文件redis.conf中158行的一致
  19 CONF="/home/long/redis-5.0.8/redis.conf"

修改配置文件
$ sudo vim /home/long/redis-5.0.8/redis.conf 
  136 daemonize no
改爲
  136 daemonize yes
  158 pidfile /var/run/redis_6379.pid

設置自啓動
$ sudo chkconfig --add redisd
$ sudo chkconfig redisd on
$ sudo chkconfig redisd --list
查看所有開啓自啓的服務
$ sudo systemctl list-unit-files

配置完的啓停方式

$ sudo service redisd start
$ sudo service redisd stop
$ sudo service redisd restart
$ sudo /etc/init.d/redisd start
$ sudo /etc/init.d/redisd stop
$ sudo /etc/init.d/redisd restart

注意：因爲腳本里默認沒有配置restart，所以重啓命令不能用

注意：在複製腳本時出現很多空格：解決辦法在vim編輯器中輸入 :set paste

解決：公子配置的restart腳本，如下：

$ sudo cat redis-5.0.8/utils/redis_init_script
#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

### BEGIN INIT INFO
# Provides:     redis_6379
# Default-Start:        2 3 4 5
# Default-Stop:         0 1 6
# Short-Description:    Redis data structure server
# Description:          Redis data structure server. See https://redis.io
### END INIT INFO

REDISPORT=6379
EXEC=/usr/local/bin/redis-server
CLIEXEC=/usr/local/bin/redis-cli

PIDFILE=/var/run/redis_6379.pid
CONF="/home/long/redis-5.0.8/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
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
                echo "$PIDFILE does not exist, process is not running"
        else
                PID=$(cat $PIDFILE)
                echo "Stopping ..."
                $CLIEXEC -p $REDISPORT shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi
        ;;
restart)
    if [ ! -f $PIDFILE ]
	then
        echo "$PIDFILE does not exist, process is not running"
	else
        PID=$(cat $PIDFILE)
        echo "Stopping ..."
        $CLIEXEC -p $REDISPORT shutdown
        while [ -x /proc/${PID} ]
        do
			echo "Waiting for Redis to shutdown ..."
            sleep 1
        done
        echo "Redis stopped"
    fi
	if [ -f $PIDFILE ]
    then
            echo "$PIDFILE exists, process is already running or crashed"
    else
            echo "Starting Redis server..."
            $EXEC $CONF
    fi
    ;;
*)
    echo "Please use start|stop|restart"
    ;;
esac

四、配置自啓動腳本【推薦；systemctl纔是以後的潮流】

創建redis.service文件

$ sudo vim /lib/systemd/system/redis.service 
[Unit]
Description=Redis
After=network.target

[Service]
Type=forking
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/bin/redis-server /home/long/redis-5.0.8/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

或者【倆種路徑都可以，親測有效】

$ sudo vim /etc/systemd/system/redis.service 
[Unit]
Description=The redis-server Process Manager
After=syslog.target network.target

[Service]
Type=simple
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/bin/redis-server /home/long/redis-5.0.8/redis.conf  
ExecReload=/bin/kill -USR2 $MAINPID
ExecStop=/bin/kill -SIGINT $MAINPID

[Install]
WantedBy=multi-user.target

配置後的啓停命令

$ sudo systemctl stop redis
$ sudo systemctl restart redis
$ sudo systemctl start redis
$ sudo systemctl status redis

redis服務加入開機啓動
$ sudo systemctl enable redis
禁止開機自啓
$ sudo systemctl disable redis

刷新配置（剛剛配置的服務需要讓systemctl能識別，就必須刷新配置）
$ sudo systemctl daemon-reload

查看systemctl系統中所有的服務
$ sudo systemctl list-unit-files

centos8.0中開機自啓服務的存放路徑

/etc/systemd/system/multi-user.target.wants/
加入開機自啓就是給該路徑下創建一個軟連接redis.service
禁止開機自啓就是把該路徑下的軟連接redis.service刪除

測壓命令

$ redis-benchmark -h 127.0.0.1 -p 6379 -c 1000 -n 100000

在6.11秒內完成100000個請求，1000個並行客戶端，3字節有效載荷，每秒16355.91個請求

====== MSET (10 keys) ======
  100000 requests completed in 6.11 seconds

問題2

執行 make test 報錯

make[1]: 進入目錄“/home/long/redis-5.0.8/src”
You need tcl 8.5 or newer in order to run the Redis test
make[1]: *** [Makefile:271：test] 錯誤 1
make[1]: 離開目錄“/home/long/redis-5.0.8/src”
make: *** [Makefile:6：test] 錯誤 2

解決：sudo yum -y install tcl

問題3

make test中的報錯

[err]: pending querybuf: check size of pending_querybuf after set a big value in tests/unit/pendingquerybuf.tcl

the used_memory of replica is much larger than master. Master:35871904 Replica:69786768
解決辦法：增加內存，因爲我的虛擬機只有1G內存

設置完自啓動腳本後不生效。

service 命令只支持基礎 LSB 動作（即 start、stop、restart、try-restart、reload、force-reload、status）。其他動作請使用 systemctl。
