How to use the server to build our blog

about IT People in the industry , Everyone wants to have their own website to blog , For sharing your knowledge , And blogging has many benefits , For example, deepen the understanding of technical points , Get the amount of reading , To be recognized , If it develops well, you can also receive small advertisements . But how can we build our own website , Today I share my previous process of building my own website ！！
Before setting up your own blog , First of all, you have to have your own server , I won't repeat how to get the server here . We can use terminal software （ recommend xshell） Connect to our server .

When the connection is complete , Our first step is to install and configure our server through terminal software LAMP（ It refers to a group of software acronyms commonly used to run dynamic websites or servers ）, In order to let everyone better contact the process of building the server , I don't need a pagoda here LAMP Installation .

One 、 install Apache HTTP service

Apache It's the world's number one user Web Server software . It can run on almost all widely used computer platforms , Because of its cross platform and security is widely used , It's the most popular Web One of the server-side software .

 We install by executing the following command ：yum -y install httpd httpd-manual mod_ssl mod_perl mod_auth_mysql   If the returned result is as shown in the figure below, the installation is successful ：

perform systemctl start httpd.service Command to start Apache service ！！ because http yes 80 port , Now we can go through http：//+ Our server is on the public network ip Address to test whether the installation is successful . If the following appears, it indicates Apache Service installed successfully .

Two 、 Install and configure the database

The second is to install our database , Due to the use Wordpress（ I'll explain later ） Build a cloud blog , Need to use MySQL The database stores data , In this section, we will install MySQL Open source alternatives to MariaDB（MariaDB Fully compatible with MySQL）, And create a blog database . install MariaDB Server, Execute the following command ：
1、yum install -y mariadb-server If the installation is successful, the following results will appear

2、 start-up MariaDB Server, Execute the following command ：

systemctl start mariadb.

notes ： You can execute the following command to view MariaDB Server Running state systemctl status mariadb If it appears as green in the figure active (running) Indicates that the service is started successfully

3. Set the initial password of the database , Execute the following command ：
mysqladmin -u root -p password

Because this is the first time to set the password , So there are Enter Password Just go back to the car when you get there , Then enter the password you want to set （ In this example, the password we set is 12345678）, And confirm twice , Please remember the password you set , Used for database login and link operation .

4. Linked database , Execute the following command ：
mysql -uroot -p

In the presence of Enter password At the prompt , Enter the password you set above , You can log in data .

5. Create a database, and then log in to the database , We're going to create a database for the blog , Here, the database name is set to woshiliangzai（ You can also use other favorite names ）, Execute the following command to create woshiliangzai database ：
   create databasewoshiliangzai; notes ： Be sure to add a semicolon .

If you want to view the created database , You can enter the following command ：
show databases;

6. Execute the following command to exit the database connection operation. We will temporarily exit the database connection operation , Go to the next section to install PHP Language environment
exit;

because WordPress It's using PHP Language development blog platform , Users can support PHP and MySQL Database server set up their own website . Also can put the WordPress As a content management system （CMS） To use . So we will install one next PHP Language environment .

3、 ... and 、 install PHP Language environment ：

1、 Execute the following command , install PHP Environmental Science .
yum -yinstallphp php-mysql gd php-gd gd-devel php-xmlphp-common php-mbstring php-ldap php-pear php-xmlrpc php-imap

If the following appears, the installation is successful ：

2. establish PHP The test page , Execute the following command ：
echo “<?phpphpinfo();?>” > ar/wwwml/phpinfo.php

3. restart Apache service , Execute the following command ：
   systemctlrestart httpd
4. test PHP Page access http://<ECS Public address >/phpinfo.php, The following page is displayed to show PHP Language environment installed successfully .
   
   Four 、 install WordPress

Now we have built LAMP（Linux、Apache、MariaDB、PHP） Environmental Science , We began to WordPress Package . But before that, we have to know what is WordPress？ I don't know how to express this in Chinese , I quoted the online explanation ：WordPress It is one of the most widely used blogging systems in the world , It's an open source PHP Software . Because there are many users , therefore WordPress The community is very active , There are rich plug-in template resources . Use WordPress Can quickly build an independent blog website . You should be able to understand it in this way ！

Now let's install WordPress：

install wordpress, Execute the following command ：
yum -yinstallwordpress The following information is displayed to indicate that the installation is successful .

2、 modify WordPress The configuration file

Execute the following command , modify wp-config.php Point to path as path ：

cd /usr/share/wordpress Enter this directory

ln -snf /etc/wordpress/wp-config.php wp-config.php It's equivalent to wp-config.php Built a fast way to put /etc/wordpress/wp-config.php

3、 Execute the following command , Move wordpress To Apache root directory

mkdir /var/www/html/wp-blog
mv * /var/www/html/wp-blog/
4、 Execute the following command to modify wp-config.php The configuration file .
Before executing the order , Please replace the following three parameter values first .

• database_name_here： Name the database created in the previous step , This example is woshiliangzai
• username_here： Is the user name of the database , This example is root
• password_here： For the database login password , That is installation MariaDB The password we set when （ The password set in this example is 12345678）

sed -i ‘s/database_name_here/woshiliangzai/’ /var/www/html/wp-blog/wp-config.php
sed -i ‘s/username_here/root/’ /var/www/html/wp-blog/wp-config.php
sed -i ‘s/password_here/12345678/’ /var/www/html/wp-blog/wp-config.php

5、 Execute the following command to check whether the replacement is successful ：

cat -n /var/www/html/wp-blog/wp-config.php

If the above appears, the modification is considered successful .

Finally, we restart Apache（systemctl restart httpd） You can test our WordPress.

test Wordpress
When all the above steps have been completed , We can test that we are based on ECS The built cloud blog .

http://< Server's IP Address >/wp-blog/wp-admin/install.php

2. Complete... According to the following information wordpress Initialize configuration , And then click Install WordPress Button complete Wordpress initialization Site Title： Site name , for example ：Hello
   Username： Administrator user name , for example ：ebdbbd
   Password： Access password , for example ：123123123
   Your Email：email Address , Suggest a real and valid address . If there is no , You can fill in the virtual email Address , But will not be able to receive letters . Such as [email protected]

Landing successful , After logging in , You can add a blog to publish ！
