分布式缓存Redis Centos下单节点安装

摘要: Redis官网：http://redis.io 独立缓存服务器：IP：xxx.xxx.xxx.xxx 安装环境：CentOS 6.6 Redis 版本：redis-3.0 （因为 Redis3.0 在集群... 声明： 网上关于分布式缓存Redis的学习资料很多，大家可以去网上找些资料去学习。 另外 JEESZ框架面向企业的大型互联网分布式企业架构，分布式缓存是必不可少的，故这边总结了一些关于分布式缓存Redis的实战文章作为后期JEESZ分布式框架的教程，希望也可以帮助到大家，请勿吐槽。 Redis官网：http://redis.io 独立缓存服务器：IP：xxx.xxx.xxx.xxx 安装环境：CentOS 6.6 Redis 版本：redis-3.0 （因为 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，请在安装时去官网选用最新版） 用户：root 安装目录：/usr/local/redis 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 提醒：下载 3.0 版 Redis（当前最新版 redis-3.0.0-rc5.tar.gz，请在安装时去官网选用最新版） cd /usr/local/src wgethttps://github.com/antirez/redis/archive/3.0.0-rc5.tar.gz 提醒：此路径可以通过官网去下载目录copy 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： (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 --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 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

openstack学习笔记六 多节点部署之keystone

keystone 对用户进行验证，每个组件必须得实用一个用户向keystone进行注册，只有成功了，那么这个组件才能正常工作。所以当我们在创建其他组件的时候，也包括keystone本身，都得为这个组件创建一个用户名和密码 keystone也必须知道这些组件到底在什么地方，比如在那台主机上。 User 住宾馆的人 Credentials 开启房间的钥匙 Authentication 宾馆为了拒绝不必要的人进出宾馆，专门设置的机制，只有拥有钥匙的人才能进出 Token 也是一种钥匙，有点特别 Tenant 宾馆 Service 宾馆可以提供的服务类别，比如，饮食类，娱乐类 Endpoint 具体的一种服务，比如吃烧烤，打羽毛球 Role VIP 等级，VIP越高，享有越高的权限 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
