Recently, a new project, jlj-cms-erp-web, has been deployed, which requires the use of nginx+Tomcat to separate static pages from dynamic requests, thus reducing the pressure on the Tomcat server.

There is no nginx on the machine where the project is deployed (192.168.1.110), so you also need to back up the static pages generated on this machine to another machine with nginx (192.168.1.191).

First of all, install tomcat, the specific process will not be written in detail, see blog

Http://itzhongxin.blog.51cto.com/12734415/1915155

Pay attention to modify port number, jvmRoute, Context path, boot memory

Create a new www folder in the webapps folder under the project, and the files in this folder will be backed up

We use the rsync command to implement the backup between the two machines. We first configure the backed up side, that is, the machine that does not have nginx installed.

Install dependency packages

Apt-get updateapt-get install gccapt-get install maketar-zxvf rsync-3.1.2.tar.gz cd rsync-3.1.2./configure-prefix=/usr/local/rsync & & make & & make install

After installation, two bin share directories should be generated under the / usr/local/rsync directory.

Then create log, pid, conf and password under the current directory to store logs, program process numbers, configuration files and passwords, respectively.

Setting up Profil

Vim rsyncd.confuse chroot = nomax connections = 10pid file = / usr/local/rsync/pid/rsyncd.pidlog file = / usr/local/rsync/log/rsyncd.log [www] # whatever you want, but the same as the backup side! Uid = rootgid = rootpath = / opt/tomcat8.0.24/jlj-cms-erp-web/webapps/www # the path to be backed up comment = wwwbackupread only = no#write only = nolist = yeshosts allow = 192.168.1.191and24 # backup to this machine hosts dengy = * auth users = backupsecrets file = / usr/local/rsync/password/server.pass # password file path

Set password file

Vim server.pass backup:BACKup_194

Modify password file permissions

Chmod 600 server.pass

Start the rsync service

/ usr/local/rsync/bin/rsync-daemon-config=/usr/local/rsync/conf/rsyncd.conf

Whether the filter started successfully

Ps-ef | grep rsyncroot 22620 10 15:17? 00:00:00. / bin/rsync-- daemon-- config=/usr/local/rsyn/conf/rsyncd.conf

Then extract a site.zip package under / opt/tomcat8.0.24/jlj-cms-erp-web/webapps/www, which contains a large number of static HTML files, which we need to synchronize to 192.168.1.191

Next, configure the backup side, as above

After installation, two bin share directories should be generated under the / usr/local/rsync directory.

Create a pwd directory to store password files

Vim server.pass BACKup_194

Modify password file permissions

Chmod 600 server.pass

Create a new jljapp folder under / var/www and back up things to that path

Test whether the backup can be successful.

Rsync-vzrtopg-progress-password-file=/usr/local/rsync/pwd/server.pass backup@192.168.1.110::www / var/www/jljapp

* the red mark here must be the same as the module name in the rsync.conf on the backup side.

Check to see if there is a successful backup to what we need in the backup path.

Cd / var/www/jljappll

If the backup is successful, write a script

Cd / usr/local/rsync/binvim rsync backgrounds 110% www.shackle password-file=/usr/local/rsync/pwd/server.pass backup@192.168.1.110::www / var/www/jljapp

Modify script permissions

Chmod axix rsyncback_110_www.sh

Make a task plan and set the synchronization task to be carried out every Friday at 8: 00 p.m.

# back up the html*/5 generated by 110cms * / bin/sh / usr/local/rsync/bin/rsyncback_110_www.sh every five minutes

The backup is complete, and then nginx forwards the request to tomcat

Deploy project jlj-cms-erp-web on the backed up side, that is, 192.168.1.110

Unpack the project package under / opt/tomcat8.0.24/jlj-cms-erp-web/webapps and delete the compressed package

Start the project and view the log

Cd bin/./startup.sh tail-f.. / logs/catalina.out

Bind the domain name on the nginx machine, and nginx receives the access request from the client and forwards it to the corresponding tomcat server according to the address

Now the demand is that there are three domain names and three configuration files.

Cms.erp.jinlejia.com

Cmsstyle.erp.jinlejia.com

Mhelp.erp.jinlejia.com

Need to modify the configuration file of nginx, create a new jljapp folder, and put three configuration files

Cd / etc/nginx/conf.dmkdir jljapp

Copy a previously configured file for the project to modify

Cp group_js.conf jljapp/mhelp.confvim mhelp.confserver {listen 80; server_name mhelp.erp.jinlejia.com; root / var/www/jljapp/site/help; index index.html index.htm; location / {} error_page 404 500 502 503 504 / 404.html; location = / 404.html {root / usr/share/nginx/html }} cp mhelp.conf cmsstyle.confvim cmsstyle.confserver {listen 80; server_name cmsstyle.erp.jinlejia.com; root / var/www/jljapp; index index.html index.htm; location / {} error_page 404 500 502 503 504 / 404.html; location = / 404.html {root / usr/share/nginx/html }} cp sso.conf jljapp/cms.confcd jljapp/vim cms.conf upstream jljappcms {server 192.168.1.110 weight=20 max_fails=2 fail_timeout=30s; ip_hash;} server {listen 80; server_name cms.erp.jinlejia.com; root / Disk/var/www/index; index index.html index.htm; proxy_max_temp_file_size 0; large_client_header_buffers 4 16k Client_max_body_size 300m; client_body_buffer_size 128k; proxy_connect_timeout 600; proxy_read_timeout 600; proxy_send_timeout 600; proxy_buffering on; proxy_buffer_size 64k; proxy_buffers 32 64k; proxy_busy_buffers_size 128k; location / {proxy_pass http://jljappcms; proxy_set_header HOST $host Proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-FOR $proxy_add_x_forwarded_for;} # error_page 500 502 503 504 / 50x.html; # location = / 50x.html {# root / usr/share/nginx/html;}}

Finally, modify the main configuration file and add it on the last line. When nginx loads the configuration file, it automatically loads the subconfiguration file in include.

Vim nginx.confinclude / etc/nginx/conf.d/jljapp/*.conf

Restart nginx

Service nginx restart
