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
