Install the Redis and MongoDB tutorials under CentOS 7 _linux

The previous article toss the node.js, this time toss down Redis and MongoDB, so basically install a good nodejs of the whole development environment.

Redis

CentOS under the installation of Redis is also relatively simple, follow the steps step-by-step operation, basic will not be wrong.

1, switch to the /usr/src directory (if you are installed in another directory, note that some of the following path to be modified), download Redis, currently the latest is 2.8.13 version
D/usr/src

wget http://download.redis.io/releases/redis-2.8.13.tar.gz

2, decompression, switch directory

Tar xzf redis-2.8.13.tar.gz
CD redis-2.8.13

3, compile

Make make
Install

4, open redis.conf Modify the configuration file, the most important is the following lines, other settings refer to the official documents:

Daemonize Yes
loglevel notice
logfile/var/log/redis.log
dir./

5, set up the system of overcommit_memory, implementation

Vi/etc/sysctl.conf

Add a row to the file to save:

Vm.overcommit_memory = 1

Perform:

Sysctl Vm.overcommit_memory=1

6, add the startup script, execute:

Vi/etc/init.d/redis

Write the following code to save:

#!/bin/sh # # Redis Startup script for Redis Server # chkconfig:-# Description:redis are an open source, adv 
Anced 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" ' in Start ' if [-f $PIDFILE] then echo $PIDFILE exists, process is already runn ing or crashed "else echo" starting Redis server ... "$EXEC $CONF fi if [" $? "
  = "0"] then echo "Redis is running ..." FI; STOP) if [! f $PIDFILE] then echo "$PIDFILE does not exist, the process is not running" else PI
        d=$ (cat $PIDFILE) echo "Stopping ..." $REDIS _cli-p $REDISPORT SHUTDOWN While [-X ${pidfile}]
        Do echo ' Waiting for Redis to shutdown ... ' sleep 1Done 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

Set permissions and boot up:

chmod +x/etc/init.d/redis
chkconfig--add redis chkconfig Redis on

OK, it's ready now. Start Redis Use service redis startOr /etc/init.d/redis start, stop Redis's command. service redis stopOr /etc/init.d/redis stop, use Redis under Windows systems to refer to this article.

Mongodb

1, the following installation MongoDB, first download:

CD/USR/SRC
wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.6.4.tgz

2, decompression, access to the directory:

TAR-ZXVF mongodb-linux-x86_64-2.6.4.tgz-c/usr/src
cd mongodb-linux-x86_64-2.6.4

3, create the database and log directory:

mkdir Log
mkdir db

4, in the background run the way to start:

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

will display the following:

About to fork the child process, the waiting until server is ready for connections.
Forked process:4623 Child
process started successfully, parent exiting

5, set up boot:

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, it's done, and then you can see the lower mouth. netstat -nalupt | grep mongo ：

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