[JAVA] A memo to do for the time being when building CentOS 6 series with VirtualBox

basic configuration

If you build Linux with VirtualBox, you can put it in for the time being

• Add NAT in VirtualBox> File> Preferences> Network

It's annoying if the IP changes every time you start up

# vi /etc/sysconfig/network-scripts/ifcfg-eth1
    IPADDR=192.168.56.102
    BOOTPROTO=static
    ONBOOT=yes

• When the host-only adapter is set to network 2 when creating with VirtualBox. If it is network 1, eth0
• For VirtualBox, 192.168.56.101 is the host. Increment from 102

Proxy settings (if required)

Assuming that the proxy server is proxy.ex.co.jp, port 8080

# vi /etc/environment
    http_proxy="http://proxy.ex.co.jp:8080/"
    HTTP_PROXY="http://proxy.ex.co.jp:8080/"
    https_proxy="https://proxy.ex.co.jp:8080/"
    HTTPS_PROXY="https://proxy.ex.co.jp:8080/"
    ftp_proxy="ftp://proxy.ex.co.jp:8080/"
    FTP_PROXY="ftp://proxy.ex.co.jp:8080/"

Is there a network restart (or ifup / down)?

# service network restart

Packages that I always put in

# yum -y install wget gzip perl lsof sysstat 

If you use the main machine firmly, it will be easier later if you add the following in addition to the above

yum -y nc bind-utils yum-utils ntc

Poor guy who somehow has become a habit

# setenforce 0
# vi /etc/selinux/config
    SELINUX=disabled

If you want the time to be accurate

# yum -y install ntp
# vi /etc/ntp.conf
    centos.Comment out the pool and put in NICT
    server ntp.nict.jp

# chkconfig ntpd on
# service ntpd start
# ntpq -p

# date +"%Y-%m-%d %H:%M:%S %Z"

Language system

Java

https://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html#javasejdk

The URL may change. For the time being, the JDK download page Since you have to accept it manually, drop it on your terminal and then send SCP

# rpm -i jdk-8u191-linux-i586.rpm

Add path

# vi /etc/profile
    export JAVA_HOME=/usr/java/default
    export PATH=$PATH:$JAVA_HOME/bin
    export
    CLASSPATH=.:$JAVA_HOME/jre/lib:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

I get angry that tool.jar is not found well

Ruby

# yum -y install ruby

If you want to use rbenv, refer to the official website

Service system

Make it a web server with Apache

# yum -y install httpd
# chkconfig httpd on
# iptables -A INPUT -p tcp --sport 80 -j ACCEPT
# /etc/init.d/iptables restart
# service httpd start

Make it a MySQL server

# yum -y install mysql-server
# chkconfig mysqld on
# iptables -A INPUT -p tcp --sport 3306 -j ACCEPT
# /etc/init.d/iptables restart
# service mysqld start

Others: Those who have touched

If you want to play with SNMP

# yum -y install net-snmp net-snmp-utils

• If you do not use WALK, you do not need utils

If you want to play with WordPress (single server)

# yum -y install httpd php php-mysql mysql wget

# chkconfig httpd on
# chkconfig mysqld on
# chkconfig --list | grep -e httpd -e mysql
httpd           0:off   1:off   2:on    3:on    4:on    5:on    6:off
mysqld          0:off   1:off   2:on    3:on    4:on    5:on    6:off
# 

# vi /etc/php.ini
Time zone"Asia/Tokyo"change to

# service httpd start
# service mysqld start

• Check PHP: Access http : // IP address / pipinfo.pip with the following

# vi /var/www/html/phpinfo.php
    <?php
        phpinfo();
    ?>

Create a suitable wordpress schema and user in mysql

# mysql -uroot -p

mysql > CREATE DATABASE wordpress
mysql > GRANT ALL PRIVILEGES ON wordpress.* TO wpuser@localhost

Drop the WordPress package somewhere in / tmp (check http://ja.wordpress.org/releases/ for the version)

# wget https://ja.wordpress.org/wordpress-4.9.8-ja.tar.gz
# tar zxf wordpress-4.9.8-ja.tar.gz
# cp -r wordpress /var/www/
# chown -R apache.apache /var/www/wordpress

# vi /etc/httpd/conf/httpd.conf
DocumentRoot"/var/www/wordpress"To
Directory tag attributes"/"To"/var/www/wordpress"To
Edit AllowOverride in the same tag to All

# service httpd restart

All you have to do is set the DB from the web screen

Memorandum of what you want to add (2018/11/15)

--Tomcat installation, Apache integration ~~ I may not do it recently ~~ --Python installation --ZCS (The latest one is sure to make a repository and yum, but the setup should be a shell anyway)
