Server journey from scratch - Yu Zhongxian integrated version (IP access server, LNMP compilation and installation, Lua environment and socket expansion)

Purpose and need to know before looking

Purpose ：

The first step is to establish the most basic connection between the host and the virtual machine server .
The most basic thing is not to create a new virtual machine installation linux System . Want to connect to each other , You have to set up the network configuration from the beginning .
This article says to start from scratch , In fact, we have to start from scratch .
PS: The test system environment in this article is Win10+VWMware Under the Linux CentOS 7
Your Collection and give the thumbs-up Is the biggest support for bloggers

Look ahead and know ：

We need to reach one word “ steady ”, as well as " Patience, ".

Conscious “ Diligence ” Baidu Learn to find resources It is also a powerful skill .
This article is about purity linux centos 7 Take compile install . It is not recommended that Mengxin take “ One click installation package ” Type of quick installation .
Slow compilation and installation , But it's safe .

Where is the safety ？

1. Know what you use liunx Installed in the system Callable commands .（ Know which commands can be used directly , What needs to be installed separately ）
2. During compilation and installation Errors reported in a certain step can be found in time And in this process, we can quickly practice and accumulate the foundation from scratch .
3, Know what you are accomplishing What architecture should be needed Instead of blindly installing .（ Steer a ship , Don't keep paddling ）
4. I haven't thought of .
PS： Some tough guys who get started and get started with ECS directly .

Documents to be prepared

1.VMware ( virtual machine ) —— VM12 From now on Suggest VM15 Register machine （ Crack ） Easy to find
2.Xshell6—— It is used to connect the server in the virtual machine
3.CentOS 7.iso——iso Is the suffix of the image file （4 individual GB about ）
4. And installation packages for several environments Later, I will explain it slowly according to my own needs First gather all the above 3 individual

The first step is to start from scratch ：Linux Creation of virtual machine & install CentOS 7

1. install Vmware( virtual machine ) success And download it CentOS 7 Image file
2. Running virtual machines choice file -> New virtual machine
Let's start Click with the picture

thus , We have taken the first step from scratch . Our virtual machine is created and installed CentOS 7 Pure system
Carry out our “ steady ” The attitude of ： The new virtual machine we created is “ snapshot ”
PS: snapshot —— A snapshot is similar to a snapshot of a system “ Backup ”. however “ Backup ” It's a complete copy , and “ snapshot ” It is the system return according to the operation record time point , Be similar to “ Undo until you mark the undo point ”. Can be interpreted as photoshop History in .

The first step is to start from scratch complete ！！！！

The second step is to start from scratch ： The host connects to the virtual machine server remotely & browser ip Web access

One 、 The host connects to the virtual machine server remotely

1. Install well Xshell 6 as well as Get ready nginx.tar.gz 、pcre.tar.gz 、zlib.tar.gz Installation package （apache It's OK , Here I'm going to demonstrate nginx web Service Framework ）.—— Yes, Baidu. lnmp Environment installation package to download resources .
2. a key ： Get ready for you —— Take notes —— Text .
3. With —— As Administrator —— start-up VMware virtual machine .
4. Configure the virtual machine network . Start following the diagram ：

5. Run on the host Xshell 6. Start following the diagram ：
!

Two 、 browser ip Web access

1. Start in Xshell 6 Start compiling and installing on our server .（ I'll use nginx Installation package Resources prepare themselves , Don't ask why I don't link to resources ？ Because after a period of time, the link will fail ）
2. Start Input Code + Note taking ：
PS:Xshell 6 in The shortcut keys for pasting are Shift + insert

install nginx

yum Commands are front-end software management commands It can be understood as yum It is just for installation yum install It means to install all
install nginx rely on ：

yum install gcc gcc-c++ openssl openssl-devel cyrus-sasl-md5

In the future ——》 choice y that will do

Come here nginx Depend on installation to complete .

stay root Under the directory, we create a folder soft . And upload our software installation package to this folder .

mkdir soft

cd soft

Install upload command

yum  install lrzsz

Input rz Upload

rz

use ls Lists the files

Unzip the installation package

tar -zxf nginx-1.10.1.tar.gz 
tar -zxf pcre-8.42.tar.gz 
tar -zxf zlib-1.2.8.tar.gz

Enter the nginx Folder , And install and configure （ Encountered configuration related information before installing the software )

cd nginx-1.10.1
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-pcre=../pcre-8.42 --with-zlib=../zlib-1.2.8

configured . Then install

make && make install

thus ,nginx Installation completed .

Then we need to modify the firewall . take CentOS7 Default firewall As firewall, change to iptables A firewall .

close firewall also prohibit firewall Boot up ：

systemctl stop firewalld.service                                    
systemctl disable firewalld.service     

install iptables A firewall ：

yum install iptables-services  

Modify firewall profile add to 80 Port allow access settings .

vi /etc/sysconfig/iptables    

stay -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT Add next line of
-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT

Restart the firewall for the configuration to take effect & Set the firewall to power on

systemctl restart iptables.service                              
systemctl enable iptables.service   

start-up ngxin service & And see if nginx Successful startup

cd /usr/local/nginx/sbin/ 
./nginx 
ps aux|grep nginx

Back to host Open the browser to access the virtual machine IP Address

Home page file storage path ：

cd /usr/local/nginx/html/
ls
