独立缓存服务器: LinuxCentOS
Redis版本: 3.0
下面我们针对于Redis安装做下详细的记录:
编译和安装所需的包:
#yum install gcc tcl创建安装目录:
#mkdir /usr/local/redis
解压:
#tar -zxvf 3.xx.tar.gz
#mv redis-3.xx redis3.0
#cd redis3.0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-dumpredis-cli redis-server
将Redis配置成服务:
按上面的操作步骤,Redis的启动脚本为:/usr/local/src/redis3.0/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/redis3.0/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
提醒: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;(特别注意: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/redis3.0/redis.conf到/usr/local/redis/conf目录并按端口号重命名为6379.conf
#cp /usr/local/src/redis3.0/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 --dport6379 -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
daemonizeno改为daemonizeyes
备注:如果不改为yes,pid文件是不会生成,start、stop命令是不会生效的(依赖pid文件)
pidfile /var/run/redis.pid改为pidfile /var/run/redis_6379.pid
启动Redis服务
#service redis start
将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
当前可以直接使用redis-cli等redis命令了:
#redis-cli
关闭Redis服务
#service redis stop提醒:默认情况下,Redis开启安全认证,可以通过/usr/local/redis/conf/6379.conf的requirepass指定一个验证密码
在jeesz中主要使用redis做分布式缓存,存储登录用户信息,做session共享管理
