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
d /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
