如何开机自启动
启动脚本 redis_init_script 位于位于redis的 /utils/目录下
复制此脚本文件至/etc/init.d目录下
-
cp /usr/local/redis-3.0.5/utils/redis_init_script /etc/init.d/redis
修改文件
- vi /etc/init.d/redis
-
#!/bin/sh
-
# chkconfig: 2345 80 90
-
# Simple Redis init.d script conceived to work on Linux systems
-
# as it does use of the /proc filesystem.
-
-
REDISPORT=6379
-
EXEC=/usr/local/redis-3.0.5/src/redis-server
-
CLIEXEC=/usr/local/redis-3.0.5/src/redis-cli
-
-
PIDFILE=/var/run/redis_${REDISPORT}.pid
-
CONF="/etc/redis/${REDISPORT}.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
-
;;
-
*)
-
echo "Please use start or stop as first argument"
-
;;
- esac
和原配置文件相比：
1.原文件是没有以下第2行的内容的，
#chkconfig: 2345 80 90
我自己改写的文件
-
#!/bin/bash
-
# Startup script for the redis
-
# chkconfig: 2345 80 90
-
# description: The redis daemon is a network memory cache service.
-
# processname: redis
-
# pidfile: /var/run/redis.pid
-

-

-
PIDFILE=/var/run/redis_${REDISPORT}.pid
-
CONF="/etc/redis/${REDISPORT}.conf"
-

-

-
# Source function library.
-

-
# Source networking configuration.

-
# Check that networking is up.
-
[ ${NETWORKING} = "no" ] && exit 0
-
[ -x $EXEC ] || exit 0
-
# Start redis daemons functions.
-
start() {
-
if [ -f $PIDFILE ];then
-
echo "$PIDFILE exists, process is already running or crashed"
-
exit 1
- fi
-
echo $"Starting $prog: "
-
$EXEC $CONF &
-
RETVAL=$?
-
return $RETVAL
-
}
-
# Stop redis daemons functions.
-
stop() {
-
if [ ! -f $PIDFILE ];then
-
echo "$PIDFILE exists, process is already running or crashed"
-
exit 1
- fi
-
echo -n $"Stopping $prog: "
-
PID=$(cat $PIDFILE)
-
$CLIEXEC -p $REDISPORT shutdown
-
while [ -x /proc/${PID} ]
-
do
-
echo "Waiting for Redis to shutdown ..."
-
sleep 1
- done
-
echo "redis stopped"
-
RETVAL=$?
-
}
-
# See how we were called.
-
case "$1" in
-
start)
- start
-
;;
-
stop)
- stop
-
;;
-
restart|reload)
- stop
- start
-
;;
-
*)
-
echo $"Usage: $prog {start|stop|restart|reload}"
-
exit 1
- esac
- exit $RETVAL
你喜欢的话，也可以用我改写的噢
2.原文件EXEC、CLIEXEC参数，也是有所更改
-
EXEC=/usr/local/redis/bin/redis-server
-
CLIEXEC=/usr/local/redis/bin/redis-cli
3.redis开启的命令，以后台运行的方式执行，加上 &
-
$EXEC $CONF &
ps:注意后面的那个“&”，即是将服务转到后面运行的意思，否则启动服务时，redis服务将 占据在前台，占用了主用户界面，造成其它的命令执行不了。
将redis配置文件拷贝到/etc/redis/${REDISPORT}.conf
-
mkdir /etc/redis
- cp /usr/local/redis-3.0.5/redis.conf /etc/redis/6379.conf
修改此配置文件
-
daemonize no //修改为yes 使redis以守护进程模式启动
-
-
pidfile /var/run/redis.pid //修改为/var/run/redis_6379.pid 设置redis的PID文件的路径
赋予redis文件执行权限
- chmod +x /etc/init.d/redis
添加服务
- chkconfig --add redis
设置开机启动
- chkconfig --level 35 redis on
查看是否设置成功
- chkconfig --list | grep redis
此状态下表面开机启动成功
service方式启动redis服务
- service redis start
service方式停止redis服务
- service redis stop
将redis的命令所在目录添加到系统参数PATH中
修改profile文件：
-
vi /etc/profile
追加
-
export PATH=$PATH:$JAVA_HOME/bin:/usr/local/redis-3.0.5/src
使配置文件立即生效
-
source /etc/profile
这样就可以直接调用redis-cli的命令了，如下所示：
退出客户端输入quit即可
检测后台进程是否存在
- ps -ef|grep redis
检测6379端口是否在监听
- netstat -tunpl | grep 6379
密码认证
打开 /etc/redis.conf 修改 requirepass 配置项
-
# vim /etc/redis.conf
-
- requirepass test123
-
# service redis restart
-
Stopping redis-server: [ OK ]
-
Starting redis-server: [ OK ]
-
-
# redis-cli
-
redis 127.0.0.1:6379> set h helloworld
-
(error) ERR operation not permitted
auth test123
-
redis 127.0.0.1:6379> auth test123
- OK
-
redis 127.0.0.1:6379> set h helloworld
- OK
-
redis 127.0.0.1:6379> get h
- "helloworld"
-
redis 127.0.0.1:6379> exit
redis-cli -a 参数指定密码
-
# redis-cli -a test123
-
redis 127.0.0.1:6379> set h helloworld
- OK
-
redis 127.0.0.1:6379> get h
- "helloworld"
-
redis 127.0.0.1:6379> exit
通过 config 动态改变密码，无需重新启动 redis 进程
-
# redis-cli -a test123
-
redis 127.0.0.1:6379> config get requirepass
-
1) "requirepass"
-
2) "test123"
-
redis 127.0.0.1:6379> config set requirepass passabc
- OK
-
redis 127.0.0.1:6379> auth passabc
- OK
-
redis 127.0.0.1:6379> set h helloworld
- OK
-
redis 127.0.0.1:6379> get h
- "helloworld"
-
redis 127.0.0.1:6379> exit
master/slave 模式， master 有密码, slave 怎样配置？
- masterauth password
redis的主从配置
1、选中一台服务器作为master
2、其它服务器作为slave
修改/etc/redis/6379.conf配置文件
找到# slaveof <masterip> <masterport>
把此配置注释放开，写上master的ip 端口号即可
如
-
slaveof 192.168.1.101 6379
重启服务，即可发现master机子中的相关数据已经同步到所有的slave从机中
