Redis
在CentOS下安装Redis也比较简单,按照步骤一步一步的操作,基本不会出错。
1、切换到/usr/src 目录(如果你安装在别的目录,注意后面要一些路径也要修改),下载Redis,目前最新的是2.8.13版本
cd /usr/src wget http://download.redis.io/releases/redis-2.8.13.tar.gz
2、解压,切换目录
tar xzf redis-2.8.13.tar.gz cd redis-2.8.13
3、编译
make make install
4、打开redis.conf 修改配置文件,最关键是下面几行,其他的设置参考官方文档:
daemonize yes bind 127.0.0.1 loglevel notice logfile /var/log/redis.log dir ./
5、设置系统的overcommit_memory,执行
vi /etc/sysctl.conf
在文件中添加一行,保存:
vm.overcommit_memory = 1
执行:
sysctl vm.overcommit_memory=1
6、添加启动脚本,执行:
vi /etc/init.d/redis
写入下面的代码,保存:
#!/bin/sh # # redis Startup script for Redis Server # # chkconfig: - 90 10 # description: Redis is an open source, advanced key-value store. # # processname: redis-server # config: /etc/redis.conf # pidfile: /var/run/redis.pid REDISPORT=6379 EXEC=/usr/local/bin/redis-server REDIS_CLI=/usr/local/bin/redis-cli PIDFILE=/var/run/redis.pid CONF="/usr/src/redis-2.8.13/redis.conf" case "$1" in start) if [ -f $PIDFILE ] then echo "$PIDFILE exists, process is already running or crashed" else echo "Starting Redis server..." $EXEC $CONF fi if [ "$?"="0" ] then echo "Redis is running..." fi ;; stop) if [ ! -f $PIDFILE ] then echo "$PIDFILE does not exist, process is not running" else PID=$(cat $PIDFILE) echo "Stopping ..." $REDIS_CLI -p $REDISPORT SHUTDOWN while [ -x ${PIDFILE} ] do echo "Waiting for Redis to shutdown ..." sleep 1 done echo "Redis stopped" fi ;; restart|force-reload) ${0} stop ${0} start ;; *) echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2 exit 1 esac
设置权限和开机启动:
chmod +x /etc/init.d/redis chkconfig --add redis chkconfig redis on
ok,现在就安装好了。启动redis使用service redis start 或者/etc/init.d/redis start ,停止redis的命令service redis stop 或者/etc/init.d/redis stop
