Start exploring Rails on Linux

I installed Mysql5.0, Which is 5.0.45, a little newer than I used. Use the which command to find the mysql path, which is usrbinmysql, and then find the mysql server in etcinit. d.

I couldn't open the ICBC website two days ago, and then I saw the news that the announcement on the ICBC website regarding the price increase of service fees is missing. It is estimated that the incident will soon be terminated. Last night, QQ suddenly fell offline for a while. Later, I entered the QQ mailbox and found an announcement on the home page, to the effect of backbone network faults. As a result, I couldn't enter the QQ mailbox today, I can't see seven emails displayed on QQ.

Since the project will be deployed on Linux, I started to study this. Previously, RHEL5 was installed on the virtual machine, so we recommended the operating system to the customer.

The two books Rails Cookbook and agile Web development-applying Rails for agile Web development are in front of us. The Rails deployment solution has been read one or two times, but in practice, I really don't know where to start.

We decided to start by installing mysql and ruby. It was hard to download the rpm package of MySQL5.1, but it was prompted that the package was in conflict with MySQL 5.0 during installation. It was found that Mysql5.0 was installed when the system was installed, which was 5.0.45, a little newer than what I used. Use the which command to find the mysql path, which is/usr/bin/mysql, and then in/etc/init. d. Find the mysql service file. mysql is found on the Internet. Here I see mysqld, run/etc/init. d/mysqld start, mysql service starts successfully. Use/usr/bin/mysql to log on to mysql through the command line.

The following is ruby. Use which ruby to find the ruby path, confirm the installation, and use ruby-v to check the version. It is 1.8.5. Go to the ruby website and check that version 1.9 has been released. You are downloading the source code. The next step is to study how to upgrade with rpm. It is best to upgrade the version, otherwise, uninstall the old version before installing the new version.

After an afternoon of hard work, the intermediate virtual machine encountered a problem.
