在 Linux Mint 18.3 安裝 OSX

Posted on 2018-01-19 by hoyo

如果你有一台還不錯的電腦，又剛好需要測試很多作業系統或是不同的瀏覽器，那使用虛擬機器是不錯的選擇

—

安裝 Vagrant

sudo apt-get install virtualbox
sudo apt-get install vagrant

1 2	sudo apt-get install virtualbox sudo apt-get install vagrant

所以 Vagrant 的底層還是 VirtualBox

—

選擇 OSX 以及安裝啟動

Discover Vagrant Boxes – Vagrant Cloud

建立虛擬主機的存放目錄

mkdir ~/osx
cd ~/osx

1 2	mkdir ~/osx cd ~/osx

準備 Vagrantfile

vi Vagrantfile


Vagrant.configure("2") do |config|
  config.vm.box = "jhcook/osx-yosemite-10.10"
end

vi Vagrantfile

Vagrant.configure("2") do |config|

config.vm.box = "jhcook/osx-yosemite-10.10"

end

啟動、下載

vagrant up

1	vagrant up

安裝 Oracle VM VirtualBox Extension Pack

沒出意外應該就會噴紅色錯誤訊息，應該是什麼沒有 USB 2.0 Controlls 之類的，叫你要安裝 VirtualBox Extension Pack

先確定 VirtualBox 版本

$ VBoxManage --version
5.0.40_Ubuntur115130

1 2	$ VBoxManage --version 5.0.40_Ubuntur115130

因為 Linux Mint 18.3 安裝出來的 VirtualBox 都還是 5.0 舊版的，所以要多花兩秒找舊版的載點

$ wget http://download.virtualbox.org/virtualbox/5.0.40/Oracle_VM_VirtualBox_Extension_Pack-5.0.40-115130.vbox-extpack
$ sudo VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-5.0.40-115130.vbox-extpack

1 2	$ wget http://download.virtualbox.org/virtualbox/5.0.40/Oracle_VM_VirtualBox_Extension_Pack-5.0.40-115130.vbox-extpack $ sudo VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-5.0.40-115130.vbox-extpack

安裝的時候有可能會遇到安裝到錯誤的版本，需要了解到底安裝了什麼鬼東西以及如何移除，所以 How to install VirtualBox Extension Pack 需要仔細的看完

—

使用圖形界面 GUI

Install VirtualBox 5.2 on Linux Mint 18 / Linux Mint 17

sudo apt-get install virtualbox-qt
virtualbox

1 2	sudo apt-get install virtualbox-qt virtualbox

如此就可以把 Vagrant 安裝完成的 OSX 呼叫出 GUI 界面，密碼也是 vagrant

—

還少了什麼？

使用 Linux 作為虛擬機器的 Host OS ，如果在這之上還可以流暢的使用 OSX 就太好了 (雖然 hoyo 已經有 MacBook 了)

不過虛擬機器的顯示卡缺點還是存在，不過現在有 GPU passthrough 的技術，應該可以解決這個問題，不過就留給下次吧

CentOS 6.7 安裝、使用 Simple RTMP Server

Posted on 2017-03-27 by hoyo

下載 for CentOS 6 適合套件

simple-rtmp-server (x86_64.zip)

解壓縮及安裝

將 zip 放到 CentOS 後

unzip SRS-CentOS6-x86_64-2.0.205.zip
cd SRS-CentOS6-x86_64-2.0.205
./INSTALL

unzip SRS-CentOS6-x86_64-2.0.205.zip

cd SRS-CentOS6-x86_64-2.0.205

./INSTALL

安裝完成後使用

/etc/init.d/srs restart

1	/etc/init.d/srs restart

啟動 SRS 服務

一般來說應該會看到 LISTEN 1935 的 RTMP Server

CentOS 7 minimal 安裝 Server – PHP7 + Apache 2.4 + MySQL 5.6

Posted on 2017-03-19 by hoyo

取得 CentOS 7

Download CentOS

選 Minimal ISO 下載即可，下載後是燒光碟還是 USB 就要看安裝主機的支援程度。

安裝及基礎設定

How to Install a CentOS 7.3 Minimal Server

網路

查看 IP ，minimal 沒有 ifconfig 只有 ip

ip link

ip link

修改設定啟用網路卡

vi /etc/sysconfig/network-scripts/ifcfg-enp3s0

ONBOOT=yes

vi /etc/sysconfig/network-scripts/ifcfg-enp3s0

ONBOOT=yes

重新啟動網路服務

systemctl restart network

1	systemctl restart network

安裝 ifconfig, netstat

yum install net-tools

1	yum install net-tools

—

安裝 ssh

yum install openssh

1	yum install openssh

systemctl restart sshd.service
systemctl enable sshd.service

1 2	systemctl restart sshd.service systemctl enable sshd.service

—

設定主機名稱 hostname

最小化安裝不會主動設置 hostname ，不設置很多服務是跑不起來的

vi /etc/hosts

192.168.0.3  myserver

vi /etc/hosts

192.168.0.3 myserver

或是使用 hostnamectl 指令

hostnamectl set-hostname MyHostName

1	hostnamectl set-hostname MyHostName

安裝 PHP 7 + Apache 2.4 + MySQL 5.6

How to Install PHP 7.0, Apache 2.4, & MySQL 5.6 on CentOS / RHEL 7.1 & 6.7

安裝 epel

yum install epel-release
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
rpm -Uvh http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

yum install epel-release

rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

rpm -Uvh http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

rpm 是否為非必要？需要再驗證。

安裝 PHP 就會一併安裝 Apache 2.4

yum install php70w
yum install php70w-mysql php70w-xml php70w-soap php70w-xmlrpc
yum install php70w-mbstring php70w-json php70w-gd php70w-mcrypt

yum install php70w

yum install php70w-mysql php70w-xml php70w-soap php70w-xmlrpc

yum install php70w-mbstring php70w-json php70w-gd php70w-mcrypt

設定 PHP

vi /etc/php.ini

upload_max_filesize = 2000M

vi /etc/php.ini

upload_max_filesize = 2000M

設定 Apache 2.4 HTTP Server

systemctl start httpd.service
systemctl enable httpd.service
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

systemctl start httpd.service

systemctl enable httpd.service

firewall-cmd --permanent --zone=public --add-service=http

firewall-cmd --permanent --zone=public --add-service=https

firewall-cmd --reload

安裝 MySQL Server

hoyo 不推薦使用 MariaDB ，雖然 MariaDB 是 MySQL 的分支，可是「並不是完全相容」，現階段 (2017-03) hoyo 還不會使用 MariaDB 當作主資料庫

# rpm -Uvh http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
# yum install -y mysql-server
# systemctl start mysqld.service
# systemctl enable mysqld.service

# rpm -Uvh http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm

# yum install -y mysql-server

# systemctl start mysqld.service

# systemctl enable mysqld.service

變更 root 密碼及移除預設資料

mysql_secure_installation

1	mysql_secure_installation

—

MySQL

修改 root 密碼

UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root';
FLUSH PRIVILEGES;

1 2	UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root'; FLUSH PRIVILEGES;

修改 /etc/mycnf 設定

vi /etc/my.cnf

[mysqld]
bind-address = 0.0.0.0
sql_mode=

vi /etc/my.cnf

[mysqld]

bind-address = 0.0.0.0

sql_mode=

bind-address 常駐 IP，預設常駐 any 可能運作在 IPv6，如果需要運作在 IPv4 就需要手動修改
sql_mode 如果需要移植舊程式

重新啟動 MySQL Server

systemctl restart mysql

1	systemctl restart mysql

修改防火橋

firewall-cmd --permanent --zone=public --add-service=mysql
firewall-cmd --reload

1 2	firewall-cmd --permanent --zone=public --add-service=mysql firewall-cmd --reload

—

安裝 phpMyAdmin

4.4 版本使用這個

yum install phpmyadmin

1	yum install phpmyadmin

新版 4.7 以上使用這個

yum remove php-mysql
yum install php-mysqlnd
yum --enablerepo=remi install phpMyAdmin

yum remove php-mysql

yum install php-mysqlnd

yum --enablerepo=remi install phpMyAdmin

將允許進入 IP 加入設定檔，編輯

vi /etc/httpd/conf.d/phpMyAdmin.conf

Require ip 192.168.0.0/24

vi /etc/httpd/conf.d/phpMyAdmin.conf

Require ip 192.168.0.0/24

重新啟動 Apache

systemctl restart httpd.service

1	systemctl restart httpd.service

如果需要修改 phpMyAdmin ，設定檔在 /etc/phpMyAdmin/config.inc.php

例如：需要延長閒置時間以及不檢查版本

vi /etc/phpMyAdmin/config.inc.php

$cfg['VersionCheck'] = false; // 不檢查新版本
$cfg['LoginCookieValidity'] = 86400; // 將閒置時間設定為 86400 秒 (1440)
$cfg['MaxNavigationItems'] = 100; // 導覽樹分支數量設定 100 (50)

vi /etc/phpMyAdmin/config.inc.php

$cfg['VersionCheck'] = false; // 不檢查新版本

$cfg['LoginCookieValidity'] = 86400; // 將閒置時間設定為 86400 秒 (1440)

$cfg['MaxNavigationItems'] = 100; // 導覽樹分支數量設定 100 (50)

安裝 DNS Server – Bind

yum install bind

1	yum install bind

修改設定檔

vi /etc/named.conf

options {
    listen-on port 53 { 127.0.0.1; 192.168.0.3; };
    allow-query { any; }; // 自己管理 DNS Server 所以必須開放查詢
    recursion no;
};

zone "hoyo.idv.tw" in {
    type master;
    file "/etc/named/hoyo.idv.tw.db";
};

vi /etc/named.conf

options {

listen-on port 53 { 127.0.0.1; 192.168.0.3; };

allow-query { any; }; // 自己管理 DNS Server 所以必須開放查詢

recursion no;

};

zone "hoyo.idv.tw" in {

type master;

file "/etc/named/hoyo.idv.tw.db";

};

重新啟動 named service 以及設定開機啟動

systemctl enable named
systemctl start named.service

1 2	systemctl enable named systemctl start named.service

開放防火牆

firewall-cmd --permanent --zone=public --add-service=dns
firewall-cmd --reload

1 2	firewall-cmd --permanent --zone=public --add-service=dns firewall-cmd --reload

從舊的主機複製資料

因為都有安裝 samba ，所以思路就是將複製的資料掛載到目的主機，然後進行複製

yum install cifs-utils
mount.cifs //192.168.0.3/root /mnt/web -o user=user

1 2	yum install cifs-utils mount.cifs //192.168.0.3/root /mnt/web -o user=user

user backup backup

cd backup

lcd /tmp

put web$filename.tgz

put db$filename.sql

就如文章內所說，可以從 FreeBSD 用到 Linux ，只要修改第一行 shell 以及指令相關路徑即可運作，不過 minimal CentOS 7 沒有 ftp command ，所以運作前需要補一個

安裝新硬碟

先使用 fdisk 分割硬碟

fdisk /dev/sdb

1	fdisk /dev/sdb

然後使用 mkfs.xfs 指令格式化硬碟

mkfs.xfs -f /dev/sdb1

1	mkfs.xfs -f /dev/sdb1

mkdir /WEBSite

1	mkdir /WEBSite

將新硬碟掛載到目錄上

mount -t xfs /dev/sdb1 /WEBSite

1	mount -t xfs /dev/sdb1 /WEBSite

使用 df 指令驗證正確性

df -TH /WEBSite

gpgcheck=0

雖然網路上所有的資料都有設定 gpgkey 但是都沒有說明產生的方法，所以如果有正常使用必須將 gpgcheck 設定為 0
