A. Installation node

1. Go to the / usr directory, the new directory toos

cd /usr && mkdir tools && cd tools

2.wget node command to download the corresponding version of the package, download version 8.11.2 here

wget https://npm.taobao.org/mirrors/node/v8.11.2/node-v8.11.2-linux-x64.tar.gz

3. Extract node package, and then change the directory named nodejs

tar xvf node-v10.13.0-linux-x64.tar.xz// decompression
mv node-v10.13.0-linux-x64 nodejs// rename

tar -zxf node-v8.11.2-linux-x64.tar.gz

mv node-v8.11.2-linux-x64 nodejs

4. configuration environment variable, so that the command can be used globally node

Into the etc directory, edit the profile file

cd /etc && vim profile

Finally, add the following code in the file:

export NODE_HOME=/usr/tools/nodejs
export PATH=$NODE_HOME/bin:$PATH
export NODE_PATH=$NODE_HOME/lib/node_modules:$PATH

Back / directory, execute

source /etc/profile

Use the reboot command to restart to take effect

Refresh configuration command. Run the node -v in any directory, display the current configuration node version that is installed successfully.

Second, install nginx

1. Installation of dependencies

yum install gcc-c++

yum install -y pcre pcre-devel

yum install -y zlib zlib-devel

yum install -y openssl openssl-devel

2. Use the wget command to download (Recommended)

wget -c https://nginx.org/download/nginx-1.10.1.tar.gz

or

wget -c https://nginx.org/download/nginx-1.16.0.tar.gz

3. Extract the package nginx

/ _ Here _ Do not attempt to change the name /

tar -zxvf nginx-1.10.1.tar.gz

cd nginx-1.10.1

4. default configuration

./configure

5. compile and install

make && make install

6. Find the installation path

whereis nginx

7. Configure global variables

ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx

Commonly used commands:

启动

nginx

重新加载配置

nginx -s reload

重新启动

nginx -s restart

https configuration:

This line can edit this file by executing the command vim /usr/local/nginx/conf/nginx.conf.
Since the version of the problem, the configuration file may be different wording. For example: l using isten 443 sslin place and listen 443 ssl on.
Add the page JS script.
Add redirect back-end program.
Jump achieved through the Web server.
Nginx rewrite support functions. If you do not remove pcre at compile time, you can increase the HTTP server in the rewrite ^ https (*.): // $ host $ 1 permanent ;, you can change the default port 80 request redirection to HTTPS. Modify the following:

server {
listen 443;
#填写绑定证书的域名
server_name www.domain.com; 
ssl on;
#网站主页路径。此路径仅供参考，具体请您按照实际目录操作。
root /var/www/www.domain.com; 
index index.html index.htm;   
#证书文件名称
ssl_certificate  1_www.domain.com_bundle.crt; 
#私钥文件名称
ssl_certificate_key 2_www.domain.com.key; 
ssl_session_timeout 5m;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_prefer_server_ciphers on;
location / {
   index index.html index.htm;
}
}
server {
listen 80;
#填写绑定证书的域名
server_name www.domain.com; 
#把http的域名请求转成https
rewrite ^(.*)$ https://$host$1 permanent; 
}

Tencent cloud application ssl https://console.cloud.tencent.com/ssl/detail/YHU6LMvv

nginx configuration

1. Install dependencies

// four mounted thereon a key dependent
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

2. Download and extract the installation package

// Create a folder
cd / usr / local
mkdir nginx
cd nginx
// download the tar package
wget http://nginx.org/download/nginx-1.13.7.tar.gz
tar -xvf nginx-1.13.7.tar .gz

// enter nginx directory
cd / usr / local / nginx
// execute command
./configure
// make command
make
// execute the command make install
make install

3. Configure nginx.conf

// Open the configuration file

we /usr/local/nginx/conf/nginx.conf

4. Start nginx

/usr/local/nginx/sbin/nginx -s reload

// Check nginx process is started:

PS -ef | grep nginx

If you want to use an external host connection on a virtual machine access port 192.168.131.2, need to shut down the virtual machine firewall:
centOS6 and previous versions use the command: systemctl stop iptables.service

centOS7 turn off the firewall command: systemctl stop firewalld.service
then access the ip to see nginx interface.

Installation commonly used commands

Enter the installation directory,

命令： cd /usr/local/nginx/sbin

Startup, shutdown, restart, the command:

./nginx start

./nginx -s stop closed

./nginx -s reload restart
