独立缓存服务器: Linux CentOS

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

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
