在CentOS 7下安装Redis和MongoDB

2014-08-05 · 11 min read

前一篇折腾了node.js,这一次折腾下 Redis 和 Mongodb,这样基本就安装好 nodejs 的整套开发环境了。

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
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 ,在 windows 系统下使用 redis 可以参考这篇文章

MongoDB#

1、下面安装 MongoDB,先下载:

cd /usr/src
wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.6.4.tgz

2、解压,进入目录:

tar -zxvf mongodb-linux-x86_64-2.6.4.tgz -C /usr/src
cd mongodb-linux-x86_64-2.6.4

3、创建数据库和日志的目录:

mkdir log
mkdir db

4、以后台运行方式启动:

./bin/mongod --dbpath=./db --logpath=./log/mongodb.log --fork --auth

会显示如下内容:

about to fork child process, waiting until server is ready for connections.
forked process: 4623
child process started successfully, parent exiting

5、设置开机启动:

echo "/usr/src/mongodb-linux-x86_64-2.6.4/bin/mongod --dbpath=/usr/src/mongodb-linux-x86_64-2.6.4/db --logpath=/usr/src/mongodb-linux-x86_64-2.6.4/log/mongodb.log --fork --auth" >> /etc/rc.local

ok,搞定,然后可以参看下端口netstat -nalupt | grep mongo

tcp   0   0 0.0.0.0:27017    0.0.0.0:*    LISTEN     4623/./bin/mongod
