redis安装(单节点)

# tar -zxvf redis.tar.gz

# cd redis

安装(使用 PREFIX 指定安装目录):

# make PREFIX=/usr/local/redis install

安装完成后,可以看到/usr/local/redis 目录下有一个 bin 目录,bin 目录里就是 redis 的命令脚本: redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server

Redis 配置成服务:

按上面的操作步骤,Redis 的启动脚本为:/usr/local/src/redis/utils/redis_init_script

将启动脚本复制到/etc/rc.d/init.d/目录下,并命名为 redis:

# cp /usr/local/src/redis/utils/redis_init_script /etc/rc.d/init.d/redis

编辑/etc/rc.d/init.d/redis,修改相应配置,使之能注册成为服务:

# vi /etc/rc.d/init.d/redis #!/bin/sh

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

# as it does use of the /proc filesystem.

REDISPORT=6379

EXEC=/usr/local/bin/redis-server

CLIEXEC=/usr/local/bin/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

查看以上 redis 服务脚本,关注标为橙色的几个属性,做如下几个修改的准备:

(1) 在脚本的第一行后面添加一行内容如下:

#chkconfig: 2345 80 90

(如果不添加上面的内容,在注册服务时会提示:service redis does not support chkconfig)

(2) REDISPORT 端口保持 6379 不变;(注意,端口名将与下面的配置文件名有关)

(3) EXEC=/usr/local/bin/redis-server 改为 EXEC=/usr/local/redis/bin/redis-server

(4) CLIEXEC=/usr/local/bin/redis-cli 改为 CLIEXEC=/usr/local/redis/bin/redis-cli

(5) 配置文件设置:

创建 redis 配置文件目录

# mkdir /usr/local/redis/conf

复制 redis 配置文件/usr/local/src/redis/redis.conf /usr/local/redis/conf 目录并按端口

号重命名为 6379.conf

# cp /usr/local/src/redis/redis.conf /usr/local/redis/conf/6379.conf

做了以上准备后,再对 CONF 属性作如下调整:

CONF="/etc/redis/${REDISPORT}.conf" 改为 CONF="/usr/local/redis/conf/${REDISPORT}.conf"

(6) 更改 redis 开启的命令,以后台运行的方式执行: $EXEC $CONF & #“&”作用是将服务转到后面运行

修改后的/etc/rc.d/init.d/redis 服务脚本内容为:

#!/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/bin/redis-server

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

PIDFILE=/var/run/redis_${REDISPORT}.pid

CONF="/usr/local/redis/conf/${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

以上配置操作完成后,便可将 Redis 注册成为服务:

# chkconfig --add redis

防火墙中打开对应的端口

# vi /etc/sysconfig/iptables

添加:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 6379 -j ACCEPT

重启防火墙:

# service iptables restart

修改 redis 配置文件设置:

# vi /usr/local/redis/conf/6379.conf

修改如下配置

daemonize no 改为> daemonize yes

pidfile /var/run/redis.pid 改为> pidfile /var/run/redis_6379.pid

启动 Redis 服务

# service redis start

Redis 添加到环境变量中:

# vi /etc/profile

在最后添加以下内容:

## Redis env

export PATH=$PATH:/usr/local/redis/bin

使配置生效:

# source /etc/profile

现在就可以直接使用 redis-cli  redis 命令了:

关闭 Redis 服务

# service redis stop

默认情况下,Redis 开启安全认证,可以通过/usr/local/redis/conf/6379.conf  requirepass 指定一个

验证密码。
