Redis有配置参数pidfile(例如/etc/redis.conf -检查Redis源代码)，例如:

# If a pid file is specified, Redis writes it where specified at startup
# and removes it at exit.
#
# When the server runs non daemonized, no pid file is created if none is
# specified in the configuration. When the server is daemonized, the pid file
# is used even if not specified, defaulting to "/var/run/redis.pid".
#
pidfile /var/run/redis.pid

如果它已经设置或可以设置，可以使用ps + grep来搜索进程id (pid)，而不是像这样使用:

kill $(cat /var/run/redis.pid)

如果需要，一个可以使redis停止脚本像这样(改编默认redis 5.0初始化。D脚本在redis源代码):

PIDFILE=/var/run/redis.pid
if [ ! -f $PIDFILE ]
then
    echo "$PIDFILE does not exist, process is not running"
else
    PID=$(cat $PIDFILE)
    echo "Stopping ..."
    kill $PID
    while [ -x /proc/${PID} ]
    do
        echo "Waiting for Redis to shutdown ..."
        sleep 1
    done
    echo "Redis stopped"
fi

SystemD， Ubuntu 16.04：

$ sudo systemctl is-active redis-server
active

$ sudo systemctl is-enabled redis-server
enabled

$ sudo systemctl disable redis-server
Synchronizing state of redis-server.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install disable redis-server
Removed /etc/systemd/system/redis.service.

$ sudo systemctl stop redis-server

我建议禁用Redis-server，它可以防止计算机重启时自动启动，对使用docker之类的工具非常有用。

步骤1:停止redis-server

sudo service redis-server stop

步骤2:关闭redis-server

sudo systemctl disable redis-server

如果你需要redis，你可以这样启动:

sudo service redis-server start

以root用户在终端中停止redis服务器类型

sudo service redis-server stop

停止redis-server后会显示此消息

Stopping redis-server: redis-server.

如果你想启动redis-server类型

sudo service redis-server start

如果要重新启动服务器类型

sudo service redis-server restart

如果通过snap安装Redis:

sudo snap stop redis.server

我的情况是:

/etc/init.d/redismaster stop
/etc/init.d/redismaster start

要找出你的服务名称，你可以运行:

sudo updatedb
locate redis

它会显示你系统中的每一个Redis文件。
