7 7 3. Install necessary package for the system
8 8 4. Install cafe-grader from github
9 9 5. Deploy cafe-grader on apache with Phusion Passenger
10 10
11 11 The detail of each step are provided as follows.
12 12
13 13 === Install MySQL 5
14 14
15 15 Install MySQL server for the server.
16 16
17 17 cafe@grader:~$ sudo apt install mysql-server
18 18
19 19 Next, we will connect to mysql as root and set up the database. You can choose your DATABASENAME, USERNAME and PASSWORD.
20 20
21 21 cafe@grader:~$ sudo mysql -u root
22 22
23 23 mysql> create database DATABASENAME;
24 24 Query OK, 1 row affected (0.00 sec)
25 25
26 26 mysql> grant all privileges on grader.* to USERNAME@localhost identified by 'PASSWORD';
27 27 Query OK, 0 rows affected, 1 warning (0.00 sec)
28 28
29 29 mysql> flush privileges;
30 30 Query OK, 0 rows affected (0.00 sec)
31 31
32 32 === Install RVM
33 33
34 34 Since Ubuntu has dedicated package for RVM we will use that. Just follow instruction given in https://github.com/rvm/ubuntu_rvm. For your convenience, the step are reproduced here.
35 35
36 36 First, we install necessary package for installing RVM.
37 37
38 38 cafe@grader:~$ sudo apt install software-properties-common
39 39
40 40 Second, we add the custom PPA, update the system and install RVM.
41 41
42 42 cafe@grader:~$ sudo apt-add-repository -y ppa:rael-gc/rvm
43 43 cafe@grader:~$ sudo apt-get update
44 44 cafe@grader:~$ sudo apt-get install rvm
45 45
46 46 This is very important. You have to logout and login again since RVM change a lots of system.
47 47
48 48 If you are using GUI version of Ubuntu, be sure to have Gnome Terminal (or any other terminal you are using) perform login every time. This can be done by mark the check box "Run command as a login shell" in Gnome terminal or by adding --login to bash.
49 49
50 50 === Install necessary package
51 51
52 52 cafe@grader:~$ sudo apt install libmysqlclient-dev default-jdk unzip nodejs php7.2-cli apache2 dirmngr gnupg apache2-dev
53 53
54 54 curl build-essential
55 55
56 56 === Install cafe-grader
57 57
58 58 First, ensure that RVM is installed correctly.
59 59
60 60 cafe@grader:~$ rvm
61 61
62 62 If you get a result similar to this.
63 63
64 64 Command 'rvm' not found, but there are 21 similar ones.
65 65
66 66 It is very likely that you have not re-login or you are using bash without --login. Please do so and re-read the installation of RVM on Ubuntu https://github.com/rvm/ubuntu_rvm again.
67 67
68 68 Next, we will let the install script do the work of installing cafe-grader. Please prepare the DATABASENAME, USERNAME and PASSWORD as the script will ask for that. Make sure that you run the script from the home directory of the user.
69 69
70 70 cafe@grader:~$ wget https://github.com/cafe-grader-team/cafe-grader-judge-scripts/raw/master/installer/install.sh
71 71 cafe@grader:~$ . ./install.sh
72 72
73 73 After installation is finished, grader is ready to run in development mode via WEBrick. We will try that by the following command which will start a grader accessible via http://localhost:3000/. You can try logging in to the system and verify that it is actually work.
74 74
75 75 cafe@grader:~/cafe_grader/web$ rails s
76 76
77 77 If Everything is OK, stop the WEBrick by Ctrl-C.
78 78
79 79 We are almost done. The last step is to set up apache and Phusion so that cafe-grader is served by apache.
80 80
81 81 === Deploy cafe-grader on Phusion passenger via apache
82 82
83 83 This will install a Passenger mod for apache. You can start by visiting https://www.phusionpassenger.com/library/walkthroughs/deploy/ruby/ownserver/apache/oss/install_passenger_main.html and fllow through the guide. We have reproduce the step here for Ubuntu 18.04. For other version, please select the appropriate one on the previous link.
84 84
85 85 The deploy is divided into two parts: Installing Passenger and deploying the app.
86 86
87 87 1. Installing Passenger as a mod for apache via PPA and enable it.
88 88
89 89 cafe@grader:~$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
90 90 cafe@grader:~$ sudo apt-get install -y apt-transport-https ca-certificates
91 91 cafe@grader:~$ sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger bionic main > /etc/apt/sources.list.d/passenger.list'
92 92 cafe@grader:~$ sudo apt-get update
93 93 cafe@grader:~$ sudo apt-get install -y libapache2-mod-passenger
94 94 cafe@grader:~$ sudo a2enmod passenger
95 95
96 96
97 97 cafe@grader:~$ sudo apache2ctl restart
98 98
99 99 Finally, we should check that passenger is installed correctly. Run the following command and fix anything as suggested by the command.
100 100
101 101 cafe@grader:~$ sudo /usr/bin/passenger-config validate-install
102 102
103 - Deploying the app. First, we determine the exact location of our ruby that is installed via RVM.
103 + 2. Deploying the app. First, we determine the exact location of our ruby that is installed via RVM.
104 104
105 105 cafe@grader:~$ passenger-config about ruby-command
106 106 passenger-config was invoked through the following Ruby interpreter:
107 107 Command: /home/cafe/.rvm/gems/ruby-2.3.7/wrappers/ruby
108 108 Version: ruby 2.3.7p456 (2018-03-28 revision 63024) [x86_64-linux]
109 109 To use in Apache: PassengerRuby /home/cafe/.rvm/gems/ruby-2.3.7/wrappers/ruby
110 110 To use in Nginx : passenger_ruby /home/cafe/.rvm/gems/ruby-2.3.7/wrappers/ruby
111 111 To use with Standalone: /home/cafe/.rvm/gems/ruby-2.3.7/wrappers/ruby /usr/bin/passenger start
112 112
113 113 Then, take note of the path after "Command". For this guide, it is /home/cafe/.rvm/gems/ruby-2.3.7/wrappers/ruby
114 114
115 115 Assuming that cafe-grader is installed at /home/cafe/cafe_grader, we will edit the Apache's site config file /etc/apache2/site-enabled/000-default.conf as follow.
116 116
117 117 <VirtualHost *:80>
118 118 #ServerName www.example.com
119 119
120 120 ServerAdmin webmaster@localhost
121 121 # dont forget to change the document root
122 122 DocumentRoot /home/cafe/cafe_grader/web/public
123 123
124 124 ErrorLog ${APACHE_LOG_DIR}/error.log
125 125 CustomLog ${APACHE_LOG_DIR}/access.log combined
126 126
127 127 # add Passenger
128 128 PassengerRuby /home/cafe/.rvm/gems/ruby-2.3.7/wrappers/ruby
129 129
130 130 # our cafe-grader app
131 131 <Directory /home/cafe/cafe_grader/web/public>
132 132 Allow from all
133 133 Options -MultiViews
134 134 Require all granted
135 135 </Directory>
136 136 </VirtualHost>
137 137
138 138
139 139 Be noted that we make 3 modifications: 1) change DocumentRoot, 2) add PassengerRuby option and add 3) Directory directive
140 140 As the last step, we restart apache again and the site is ready to be used.
141 141
142 142 cafe@grader:~$ sudo apache2ctl restart
143 143
144 - Now it is done, you can login to the grader with user 'root' and password 'ioionrails'
