The following is a detailed tutorial on the installation and configuration of Nginx, PHP7, Mysql, JDK, Tomcat and Redis in Centos 7.2. the secret of the text lies in being close to the topic. So, no gossip, let's take a look at the following, I believe that after reading Centos 7.2 installation and configuration of Nginx, PHP7, Mysql, JDK, Tomcat, Redis detailed tutorials this article will certainly benefit you.

Centos 7.2install and configure Nginx, PHP7, Mysql, JDK, Tomcat, Redis, RAP

The following operations are performed in Aliyun ECS (Centos 7.2) environment. Other system environments may be slightly different, for reference only.

Software update

Due to the compatibility of system drivers, the current CVM ECS Linux does not support kernel upgrade operations (for more instructions, please see ECS instructions).

Usually get a new server, I like to upgrade the software first. Ariyun ECS does not recommend upgrading the kernel and operating system version of the server, so it should be removed when updating the system software.

The following is to check the server kernel and system version, you can see before and after the software upgrade, whether to eliminate the difference.

Uname-a

Lsb_release-a

First open the / etc/yum.conf (vi / etc/yum.conf) file, and then add the following two lines of code after [main] so that the kernel and system version are not upgraded when the software is updated.

Exclude=kernel

Exclude=centos-release

Then update the software, the-y parameter is in the execution process, the interaction encountered by default yes, if you want to see the software update information, you can remove the-y parameter.

Yum-y update

Reference: Ali Cloud ECS (LINUX) update does not upgrade kernel configuration instructions

Hostname modification

View hostname directive

Hostname

The default hostname of Aliyun ECS is randomly generated, which is not very comfortable. You can modify the / etc/hostname file to change the current hostname to the name you want.

Vim / etc/hostname

Then, press ESC to enter: wq save (vim basic directive). Reboot to see if the hostname has changed.

PS: temporarily modify the hostname, and the original hostname will remain after restart.

Hostname Hostnam

Directly use yum to install the software, which may be a stable version, but not a new version. Here, change the source or compile and install the software to install the version you want.

Install NGINX

Before changing the source, you can check the version information of the system default source Nginx and compare it with the source change.

Yum info nginx

1. To change the source, first create a new repo, such as nginx.repo

Vim / etc/yum.repos.d/nginx.repo

two。 The editing content is as follows

[nginx]

Name=nginx repo

Baseurl= http://nginx.org/packages/mainline/centos/7/$basearch/

Gpgcheck=0

Enabled=1

Mainline version is configured here. If you want to use the stable version, delete the mainline in baseurl.

3. Carry out installation

Yum install nginx

4. View version

Nginx-v

5. Start the service

Systemctl start nginx

6. View statu

Systemctl status nginx

At this point, Nginx has been installed, access the server IP address (the domain name has been resolved, you can also use the domain name to access), check to see if there is a welcome page.

Reference: nginx.org

Firewall configuration

If you do not see the welcome page after the above steps, it may be caused by the firewall configuration (port 80 is not open). The default firewall for Centos 7 is FirewallD.

FirewallD has image interface tool firewall-config and command line tool firewall-cmd. Command line tool firewall-cmd is usually used on the server.

View firewall running status

Firewall-cmd-state

Enable the FirewallD service

Systemctl start firewalld

View FirewallD status

Systemctl status firewalld

View FirewallD configuration

Firewall-cmd-list-all

Enable port 80 of TCP in the default region, and add the parameter permanent, which means that the configuration will take effect permanently after reloading. The configuration without this parameter will take effect immediately, but it will become invalid after FirewallD reloading.

Firewall-cmd-permanent-add-port=80/tcp

When the firewall is on, you only need to open port 80 (the default port for Nginx) to access the page.

Close the default zone TCP port 80

Firewall-cmd-permanent-remove-port=80/tcp

Enable HTTP service (the default configuration equals to opening port TCP 80)

Firewall-cmd-permanent-add-service=http

Turn off the HTTP service (the default configuration equals to shutting down port TCP 80)

Firewall-cmd-permanent-remove-service=http

Overload configuration

Firewall-cmd-reload

Install PHP

The REMI repository provides updated versions of the core packages of CentOS and RHEL, especially the latest PHP/MySQL series

You can use the following command to view warehouse changes at any time during installation

Yum repolist all

Before installing the REMI repository, install the EPEL repository first, because some packages in REMI depend on EPEL

Yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Next, install the REMI repository

Yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Then install the configuration management tools of yum to facilitate the configuration of yum repository

Yum install yum-utils

Enable remi-php71 warehouse

Yum-config-manager-enable remi-php71

Finally, install PHP

Yum install php

After the installation is complete, check the PHP version and extension information

Php-version

Php-modules

Reference: Remi's RPM repository

Install PHP-FPM, simply understand that PHP-FPM is the manager of FastCGI, and FastCGI handles PHP scripts forwarded by Nginx.

Yum install php-fpm

Reference: what is PHP-FPM

Configure Nginx

Now that Nginx, PHP, and PHP-FPM are all installed, how do you get the PHP script running?

First, configure Nginx. The simple configuration is as follows:
