# wget http://download.redis.io/releases/redis-3.0.7.tar.gz
# tar -xvzf redis-3.0.7.tar.gz
# cdredis-3.0.7
# make
前面3步应该没有问题,主要的问题是执行make的时候,出现了异常。
异常一:
make[2]: cc: Command not found
异常原因:没有安装gcc
解决方案:yum install gcc-c++
异常二:
zmalloc.h:51:31: error: jemalloc/jemalloc.h: No such file or directory
异常原因:一些编译依赖或原来编译遗留出现的问题
解决方案:make distclean。清理一下,然后再make。
在make成功以后,需要make test。在make test出现异常。
异常一:
couldn't execute "tclsh8.5": no such file or directory
异常原因:没有安装tcl
解决方案:yum install -y tcl。
在make成功以后,会在src目录下多出一些可执行文件:redis-server,redis-cli等等。
方便期间用cp命令复制到usr目录下运行。
cp redis-server /usr/local/bin/
cp redis-cli /usr/local/bin/
然后新建目录,存放@R_404_382@
# mkdir /etc/redis
# mkdir /var/redis
# mkdir /var/redis/log
# mkdir /var/redis/run
# mkdir/var/redis/6379
在redis解压根目录中找到@R_404_382@模板,复制到如下位置。
# cp redis.conf /etc/redis/6379.conf
通过vim命令修改
daemonize yes
pidfile /var/redis/run/redis_6379.pid
logfile /var/redis/log/redis_6379.log
dir /var/redis/6379
bind 127.0.0.1 192.168.1.243
最后运行redis:
$ redis-server /etc/redis/6379.conf
在centos中开启6379端口
#vim /etc/sysconfig/iptables
-A INPUT -m state --state NEW -m tcp -p tcp --dport 6379 -j ACCEPT
#service iptables restart
可以用RedisDesktopManager查看

IP:192.168.4.111
环境:CentOS 6.6
Redis版本:redis-3.0(考虑到Redis3.0在集群和性能提升方面的特性,rc版为正式版的候选版,而且很快就出正式版)
安装目录:/usr/local/redis
用户:root
编译和安装所需的包:
#yum install gcc tcl
下载3.0版Redis(当前最新版redis-3.0.0-rc5.tar.gz,请学员们在安装时自行选用最新版)
#cd /usr/local/src
#wget https://github.com/antirez/redis/archive/3.0.0-rc5.tar.gz
创建安装目录:
#mkdir /usr/local/redis
解压:
#tar -zxvf 3.0.0-rc5.tar.gz
#mv redis-3.0.0-rc5 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-dump redis-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:
#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@R_404_382@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)@R_404_382@设置:
创建redis@R_404_382@目录
#mkdir /usr/local/redis/conf
复制redis@R_404_382@/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 --dport 6379 -j ACCEPT
重启防火墙:
#service iptables restart
#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
将Redis添加到环境变量中:
#vi /etc/profile
## 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等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的requirepass指定一个验证密码。
