9. CentOS Upgrade Git
Http://www.cnblogs.com/grimm/p/5368777.html
A.
Download the git2.2.1 and add git to the environment variable ># wget https://github.com/git/git/archive/v2.2.1.tar.gz
># tar zxvf v2.2.1.tar.gz
># cd git-2.2.1># make configure
># ./configure --prefix=/usr/local/git --with-iconv=/usr/local/libiconv
># make all doc
># make install install-doc install-html>
# echo "export PATH=$PATH:/usr/local/git/bin" >> /etc/bashrc
># source /etc/bashr
B.

This error occurred while installing the Perl module:

Can ' t locate extutils/makemaker.pm in @INC

Here's how to fix it:

1234567

Cd/rootwget Http://files.directadmin.com/services/9.0/ExtUtils-MakeMaker-6.31.tar.gztar Xvzf EXTUTILS-MAKEMAKER-6.31.TAR.GZCD Extutils-makemaker-6.31perl Makefile.plmakemake Install

C.
If you have an error in the previous step
Yum Install Perl-extutils-makemaker
D.
Also will be error, tip not to curl

For CentOS, use Yum to install curl after developing the relevant library:

$ yum Install Libcurl-devel

E. Unable to find AsciiDoc, note add path

wget http://sourceforge.net/projects/asciidoc/files/asciidoc/8.6.9/asciidoc-8.6.9.tar.gz

F. And a lack of bags

Yum Search XSLTPROC

Then install, add environment variables ...
G. warning:failed to load external entity "http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl"
Prompt to have an address file not found, workaround: yum-y Install docbook-style-xsl
H. #yum-y install Xmlto

Otherwise the compilation does not pass:

/bin/sh:line 1:xmlto:command not found
I. Git init prompt???? , and did not create a successful
chmod 777 folder used because the current user does not have permissions
At last finally ....... ..... It's going to work.


8. Deploying Flask

Encounter problems 1:uwsgi prompt cannot load configurtion from Xx.ini This configuration file can not be called Uwsgi class file name, called Myxx.ini Bar 2. Prompt cannot find manager.py, normal because there is no this file, It should be called manage.py.
1. Installing Nginx

Install the GCC compiler and related tools before installing Nginx, it is very convenient to install with Yum.

$ sudo yum-y install gcc gcc-c++ make autoconf automake

Nginx modules require third-party library support, such as gzip requires Zlib,rewrite module requires PCRE library, SSL function requires the OpenSSL library. Install it directly with Yum.

$ sudo yum-y install zlib zlib-devel OpenSSL openssl-devel pcre pcre-devel

Go to nginx official website nginx.org Download the latest version, the author download is 1.2.7 version.

$ wget http://nginx.org/download/nginx-1.2.7.tar.gz

Unzip the installation

$ tar-zxv-f nginx-1.2.7.tar.gz

$ CD nginx-1.2.7

$./configure

$ make

$ sudo make install

Here configure use the default parameters, can be modified according to their own needs. You can use the./configure–help to view help instructions.

Start the Nginx server

Sudo/usr/local/nginx/sbin/nginx-c/usr/local/nginx/conf/nginx.conf

Where/usr/local/nginx/sbin/nginx represents the start-up program, where the full path is more intuitive, you can make a soft link to the system path according to your own habits.

Using the browser to access the HTTP://127.0.0.1/, if you see the Welcome to nginx! Word, it means that the installation was successful.

2, Installation Uwsgi

Install dependent Python-devel, Setuptools,libxml2-devel, and install it directly with Yum. If you are compiling your own Python installation, you may not have to install Python-devel.

$ sudo yum-y install python-devel python-setuptools libxml2-devel

Former website http://projects.unbit.it/uwsgi/download Uwsgi, although the page is in English, but it is not difficult to find the download page.

$ wget http://projects.unbit.it/downloads/uwsgi-1.9.tar.gz

Unzip the installation:

$ tar-zxv-f uwsgi-1.9.tar.gz

$ CD uwsgi-1.9

$ python setup.py Install

3, installation Flask

Go to official website http://flask.pocoo.org/download flask.

$ wget http://pypi.python.org/packages/source/F/Flask/Flask-0.9.tar.gz

Unzip the installation

$ tar-zxv-f flask-0.9.tar.gz

$ CD Flask-0.9

$ sudo python setup.py install

Create a new Flask project, app.py a program file with the following:

from flask  import Flask app  = Flask(__name__) @app .route( "/" ) def hello(): return "Hello World!" if __name__  = = "__main__" : app.run()

Make sure that the Web server that comes with flask can run.

4. Configuring Nginx and Uwsgi

This step is more troublesome, but it is not difficult to understand the principle.

Uwsgi in Nginx 1.2.7 is a standard module, so no installation is required. Edit the Nginx configuration file so that it loads UWSGI.

Location/{
Include Uwsgi_params;
Uwsgi_pass 127.0.0.1:3031;
root HTML;
Index index.html index.htm;
}

After the modification is complete, you can test the configuration file for no errors.

$ sudo/usr/local/nginx/sbin/nginx-t-c/usr/local/nginx/conf/nginx.conf

After the configuration is complete, restart Nginx. First find the Nginx main process number:

$ PS-EF | grep nginx

The author on the computer is 13367 and then restarted

$ sudo kill-hup 13367

Create a new profile app_config.xml under the Flask project to set UWSGI related parameters, and a uwsgi will need to indicate this configuration file at startup, as follows:

< uwsgi > < pythonpath >/home/chenjiebin/web/flaskdemo</ pythonpath > < module >app</ module > < callable >app</ callable > < socket >127.0.0.1:3031</ socket > < master /> < processes >4</ processes > < memory-report /> </ uwsgi >

One of the parameters indicates:

• Pythonpath indicates the project directory
• Module represents the project startup module, as in the example above is app.py, here is the app
• Callable represents the instance name of the Flask project, the app = Flask (__name__) in the example code, so this is the app
• The socket represents the address and port of the Nginx communication, and the Uwsgi_pass in the Nginx configuration is consistent.
• Processes indicates how many child processes are opened to process the request.

Start Uwsgi:

$ sudo/usr/local/bin/uwsgi-x/home/chenjiebin/web/flaskdemo/app_config.xml

Where the-x parameter represents the loaded configuration file path.

This time in the browser to access http://localhost, see output Hello world! is done.

Tip: If you need to let Uwsgi run as a daemon, use the-D parameter and indicate the log path.

$ sudo/usr/local/bin/uwsgi-x/home/chenjiebin/web/flaskdemo/app_config.xml-d/var/log/uwsgi/uwsgi.log

Summary

The communication between Nginx and Uwsgi here is to use the port to communicate, or you can use the socket file. UWSGI configuration can also use other configuration files, not necessarily XML, here is no longer explained. There is a problem that can be exchanged for letters.

After installing MySQL

1. Allow root remote access

Use MySQL;
mysql> Update user Set host = '% ' where user = ' root ';
Mysql> Select Host, user from user;
mysql> flush Privileges;

Permissions must be refreshed

[Open/etc/conf/in [mysqld] to add a sentence: Skip-grant-tables, you can see the user Library] Sometimes, do not have permission to add a password, or, can not be logged in with a password user, or directly MySQL can log in
You need to delete the empty items in the table,
Remember to refresh permissions
and service mysqld restart.

2. Open port

Open the firewall configuration file

1
Vi/etc/sysconfig/iptables
2. Add the following line
1
-A input-m state--state new-m tcp-p TCP--dport 3306-j ACCEPT
3. Restart the firewall
