Ruby on Rails 教程第四版有优惠活动吗？

开始看封面还以为是 Ruby on Rails way.

如何在 Ubuntu 14.03 Server 上安装 mina 的一键部署环境

lotusfire — Fri, 12 Feb 2016 16:45:18 +0800

假期里把 AWS EC2 上的两台 Ubuntu 实例重新部署了一下，遇到不少坑，也从社区里面得到了不少帮助。

整理成文，希望能帮到Ruby China 社区里的其他小伙伴。相关 *.sh 均可以下载，根据自己的需要编辑使用。

转帖的时候请注明原文地址，谢谢。

1. 将自己的 Key 传到服务器上

ssh-agent bash
ssh-add ~/.ssh/ec2-instance-key.pem
ssh-copy-id -i ~/.ssh/id_rsa.pub <user_name>@<server_domain>

测试

ssh <user_name>@<server_domain>

2. 配置 Ubuntu 系统

sudo wget -O- https://raw.githubusercontent.com/lookforIO/www-zhengweiyu-com/master/installer/init-ubuntu.sh | sh

3. 安装 rvm

sudo wget -O- https://raw.githubusercontent.com/lookforIO/www-zhengweiyu-com/master/installer/rvm.sh | sh

4. 安装 Web 服务

4.1 Nginx + Passanger

sudo wget -O- https://raw.githubusercontent.com/lookforIO/www-zhengweiyu-com/master/installer/nginx-passanger.sh | sh

现在修改 nginx 配置，编辑 /etc/nginx/nginx.conf，找到这两行注释：

# passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
# passenger_ruby /usr/bin/ruby;

去除 '#' 即在 nginx 中启用了 passanger

4.2 Nginx + PHP5 + PHP5-FPM

sudo wget -O- https://raw.githubusercontent.com/lookforIO/www-zhengweiyu-com/master/installer/nginx-php5-php5fpm.sh | sh

5. 安装数据库

5.1 PostgreSQL

sudo wget -O- https://raw.githubusercontent.com/lookforIO/www-zhengweiyu-com/master/installer/postgresql.sh | sh

登录数据库

sql sudo -u postgres psql postgres

创建数据库和用户

sudo -u postgres psql postgres
create user "<user name>" with password '<password>';
/* 建议 <user name> 和 <database name> 相同 */
create database "<database name>" owner "<user name>"; 
grant all privileges on database <database name> to <user name>;

5.2 MySQL

sudo wget -O- https://raw.githubusercontent.com/lookforIO/www-zhengweiyu-com/master/installer/mysql.sh | sh

登录数据库

mysql -u root -p

创建数据库和用户

create database <database_name>;
create user <user_name>@localhost identified by '<password>';
/* 建议 <user name> 和 <database name> 相同 */
grant all privileges on <user_name>.* to <database_name>@localhost;
flush privileges;

6. 配置 mina 环境

gem install mina

在项目根目录下，执行

mina init

编辑 config/deploy.rb

Mina 部署项目

mina setup
mina deploy

7. 建立 Nginx 配置文件

sudo mkdir -p /var/www
cd /var/www
sudo ln -s /home/<user_name>/webapps/production/<project-dir>/current <project-dir>

建立 nginx 的配置文件

cd /etc/nginx/sites-available
sudo nano <your domain>

7.1 Passanger 的 nginx 文件


server {
    listen 80;
    server_name <your domian>;
    passenger_enabled on;
    root /var/www/<project-dir>/public;

    access_log off;
    error_log /var/www/<project-dir>/log/error.log;

    error_page 500 502 503 504 /500.html;
    client_max_body_size 4G;
    keepalive_timeout 10;
}

7.2 Jekyll 的 nginx 文件

server {
    listen 80;
    # listen [::]:80 ipv6only=on;

    root /var/www/<project-dir>/_site;
    index index.html;

    server_name <your domian>;

    access_log off;
    error_log /var/www/<project-dir>/log/error.log;  


    error_page 404 /404.html;

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }
}

7.3 PHP 的 nginx 文件

server {
    listen 80;
    # listen [::]:80 ipv6only=on;

    root /var/www/<project-dir>;
    index index.php index.html index.htm;

    server_name <your domian>;

    location / {
        # try_files $uri $uri/ =404;
        try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    access_log off;
    error_log /var/www/<project-dir>/log/error.log;  


    error_page 404 /404.html;

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index index.php;
        include fastcgi_params;
    }
}

8. 链接目录并重启 Nginx

链接目录

cd /etc/nginx//sites-enabled/
sudo ln -s ../sites-available/<your domian> <your domian>

重启 nginx 服务

sudo service nginx restart

如果看到

Restarting nginx nginx [ OK ]

说明配置成功。

9. 一键部署脚本

sudo wget -O- https://raw.githubusercontent.com/lookforIO/www-zhengweiyu-com/master/installer/deploy.sh | sh

All done!
