Installation and configuration of nginx and tomcat integration in Linux

1. install Tomcat and JDK

1. Upload apache-tomcat-6.0.18.tar.gz and jdk-6u12-linux-i586.bin to/usr/local
2. Run the following command to install Tomcat:

# Cd/usr/local # Tar zxvf APACHE-Tomcat- 6.0 . 18 .Tar.gz

 

After decompression, rename APACHE-Tomcat-6.0.18 to Tomcat.
3. Run the following command to install JDK:

#./Jdk-6u12-linux-i586.bin

4. Configure environment variables:
Edit the profile file in/etc with the following content:  

Java_home = "/Usr/local/jdk1.6.0 _ 12" Class_path = "$ Java_home/lib: $ java_home/JRE/lib" Path = ".: $ Path: $ java_home/bin"   Catalina_home = "/Usr/local/tomcat" Export java_home catalina_home

5. start Tomcat and enter http: // localhost: 8080. If the installation of Tomcat and JDK is successful
6. Create a new file directory/home/WWW as the website storage directory and set the server. in the XML file, change the pointing path of appbase = to/home/www/web in host name = "localhost ".
7. Create index. jsp to/home/www/web/root. The content is "My Web !"

 

Ii. Install nginx
1. Upload nginx-0.7.63.tar.gz to/usr/local

2. Run the following command to decompress nginx:

# Cd/usr/local # Tar zxvf nginx- 0.7 . 63 .Tar.gz

3. Compile and install nginx

# Cd nginx- 0.7 . 63 #./Configure -- with-http_stub_status_module -- with-http_ssl_module # Start server status page and HTTPS Module

After execution, an error will be prompted, indicating that the PCRE Library is missing. This is the HTTP rewrite module, that is, the URL static package.
You can upload pcre-7.9.tar.gz and run the following command to install it:

# Tar zxvf PCRE- 7.9 .Tar.gz # Cd PCRE- 7.9 #./Configure # Make # Make install

After PCRE is successfully installed, continue to install nginx

# Cd nginx- 0.7 . 63 #./Configure # Make # Make install

4. After nginx is installed successfully, the installation directory is/usr/local/nginx.
Create proxy. conf In the conf folder to configure some proxy parameters. The content is as follows:

#! Nginx (-) # Proxy. conf Proxy_redirect off; Proxy_set_header host $ host; Proxy_set_header X-real-IP $ remote_addr; # obtain the real IP Address # Proxy_set_header X-forwarded-for $ proxy_add_x_forwarded_for; # obtain the real IP address of the proxy Client_max_body_size 10 m; Client_body_buffer_size 128 K; Proxy_connect_timeout 90 ; Proxy_send_timeout 90 ; Proxy_read_timeout 90 ; Proxy_buffer_size 4 K; Proxy_buffers 4 32 K; Proxy_busy_buffers_size 64 K; Proxy_temp_file_write_size 64 K;

Edit nginx. conf In the conf folder under the installation directory and enter the following content:  

# Username and user group for running nginx # User WWW;   # Number of processes started Worker_processes 8 ; # Global error logs and PID files Error_log/usr/local/nginx/logs/nginx_error.log crit;   Pid/usr/local/nginx. PID;   # Specifies the value For Maximum file descriptors that can be opened This Process.   Worker_rlimit_nofile 65535 ; # Working mode and maximum number of connections Events { Use epoll; Worker_connections 65535 ; } # Set the HTTP server and use its reverse proxy function to provide Load Balancing support HTTP { # Set the MIME type Include mime. types; Default_type application/octet-stream; Include/usr/local/nginx/CONF/Proxy. conf; # Charset gb2312; # Set Request Buffer Server_names_hash_bucket_size 128 ; Client_header_buffer_size 32 K; Large_client_header_buffers 4 32 K; Client_max_body_size 8 m; Sendfile on; Tcp_nopush on;   Keepalive_timeout 60 ;   Tcp_nodelay on;   # Fastcgi_connect_timeout 300 ; # Fastcgi_send_timeout 300 ; # Fastcgi_read_timeout 300 ; # Fastcgi_buffer_size 64 K; # Fastcgi_buffers 4 64 K; # Fastcgi_busy_buffers_size 128 K; # Fastcgi_temp_file_write_size 128 K;   # Gzip on; # Gzip_min_length 1 K; # Gzip_buffers 4 16 K; # Gzip_http_version 1.0 ; # Gzip_comp_level 2 ; # Gzip_types text/plain application/X-JavaScript text/CSS application/XML; # Gzip_vary on;   # Limit_zone crawler $ binary_remote_addr 10 m;   ### Prohibit Website access through IP addresses Server { SERVER_NAME _; Return 404 ; }     Server { Listen 80 ; SERVER_NAME localhost; Index index.html index.htm index. jsp; # Set the default homepage address for access Root/home/www/web/root; # set the path for storing website resources   # Limit_conn Crawler 20 ; Location ~ . *.

Log Access; # set the path for storing access logs   }   }

5. After modifying the/usr/local/nginx/CONF/nginx. conf configuration file, run the following command to check whether the configuration file is correct:

#/Usr/local/nginx/sbin/nginx-T

If the following two lines of information are displayed, the configuration file is correct:  

The configuration file/usr/local/nginx/CONF/nginx. conf syntax is OK The configuration file/usr/local/nginx/CONF/nginx. conf was tested successfully

If the message "unknown host" is displayed, run the following command on the server: Ping www.baidu.com. If the message "unknown host" is also displayed, there are two possibilities:
A. Check whether the DNS server address is set in/etc/resolv. conf. If no DNS server address is set, add
B. Firewall Interception

6. Start nginx commands

#/Usr/local/nginx/sbin/nginx

Enter the following command to view the nginx master process number:

PS-Ef | grep "Nginx: Master process" | Grep-V "Grep" | Awk-F '' '{Print $2 }'

7. Stop nginx commands

#/Usr/local/nginx/sbin/nginx-s stop

8. smoothly change the nginx configuration without stopping the nginx Service
A. After modifying the/usr/local/nginx/CONF/nginx. conf configuration file, run the following command to check whether the configuration file is correct:

/Usr/local/nginx/sbin/nginx-T

If the following two lines of information are displayed, the configuration file is correct:

The configuration file/usr/local/nginx/CONF/nginx. conf syntax is OK The configuration file/usr/local/nginx/CONF/nginx. conf was tested successfully

B. Enter the following command to view the nginx master process number:

PS-Ef | grep "Nginx: Master process" | Grep-V "Grep" | Awk-F '' '{Print $2 }'

The screen displays the nginx main process number, for example:
6302
Then, run the following command to make the modified nginx configuration file take effect:

Kill-HUP 6302

Alternatively, you can find the nginx PID file:

Kill-HUP 'cat/usr/local/nginx. Pi'

9. Start tomcat after nginx is started. Enter http: // host IP address to view "My Web !"

 
Iii. Others
Stub_status
Syntax: stub_status on

Default Value: None

Scope: Location

Create a location region to enable stub_status

The status information returned by the stub Status Module is similar to that returned by mathopd's. The returned status information is as follows:

Active connections: 291 Server accepts handled requests 16630948 16630948 31070465 Reading: 6 Writing: 179 Waiting: 106

Active connections-number of active connections initiated to the backend

Server accepts handled requests-nginx processes a total of 16630948 connections and successfully creates 16630948 handshakes (proving that there is no failure in the middle ), A total of 31070465 requests are processed (an average of 1.8 data requests are processed in each handshake)

Reading-Number of headers that nginx reads to the client

Number of headers that writing-nginx returns to the client

When waiting-enables keep-alive, this value is equal to active-(Reading + writing), which means nginx says it has processed the resident connection waiting for the next request command.
