2. New configuration file mongodb.cnf

#Where to store the data.
dbpath=/work/mongodb-linux-x86_64-rhel70-3.4.6/data
#where to log
logpath=/work/mongodb-linux-x86_64-rhel70-3.4.6/mongodb.log
logappend=true
bind_ip=127.0.0.1
port=19130

3. New Documents

mkdir /work/mongodb-linux-x86_64-rhel70-3.4.6/data

4. Start. / mongod-f.. / mongodb. CNF & and note that mongod is under bin in the mongo directory

mysql 5.6

1. Download and install MySQL package version 5.6 file

wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm

2.yum installation

yum -y install mysql-community-release-el6-5.noarch.rpm
yum -y install mysql-community-server

3.MySQL database settings

Start MySQL `system CTL start mysqld. service first`
    
View the MySQL running status, as shown in the figure: system CTL status mysqld.service

At this time, MySQL has started to run normally, but to enter MySQL, you have to find the password of the root user at this time. You can find the password in the log file by following commands: `grep'password / var / log / mysqld. log`

The following commands enter the database: mysql-u root-p
    
Enter the initial password, and nothing can be done at this time, because MySQL must change the password by default before it can operate the database:
     
set password for root@localhost=password('root');

FLUSH PRIVILEGES;

4. Perform data schema initialization

data base mydb

create database mydb
use mydb

source /work/install/sql/db.sql

elasticsearch 5.4.2

1. Put the elastic search compression package under / work to decompress tar-zxvf elastic search-5.4.2. tar.gz

2. Unzip the elastic search-analysis-ik-5.4.2.zip to the plugins/ik in the installation directory

3. If the above command is logged in and executed by root user, you will see an error prompt requiring a new user command as follows

useradd elasearch

Modify file for all users chown-R elasearch/work/elastic search-5.4.2/

4. boot

su elasearch
./bin/elasticsearch &

5. The Library of elastic search

Notice in particular that the elastic search configuration:

/work/elasticsearch-5.4.2/config/elasticsearch.yml

Add to
network.host: 0.0.0.0
http.port: 9200
http.cors.enabled: true
http.cors.allow-origin: "*"
bootstrap.system_call_filter: false

es The default cluster name is cluster.name: my-application
 Clusters are automatically searched in the case of Intranet connectivity
 When testing es is started, be sure to specify a name that does not match the default cluster.name
