Configuring the Nginx startup script

#! /bin/bash

# Description:startup script for webserver on CentOS. CP It IN/ETC/INIT.D and

# chkconfig--add nginx && chkconfig nginx on

# then you can use Server command control Nginx

# chkconfig:2345 08 99

# Description:starts, stops Nginx

Set-e

Path= $PATH:/usr/local/nginx/sbin/

desc= "Nginx Daemon"

Name=nginx

daemon=/usr/local/nginx/sbin/$NAME

Configfile=/usr/local/nginx/conf/nginx.conf

#PIDFILE =/var/run/nginx.pid

Pidfile=/usr/local/nginx/logs/nginx.pid

Scriptname=/etc/init.d/$NAME

# Gracefully Exit If the package has been removed.

Test-x $DAEMON | | Exit 0

D_start () {

$DAEMON-C $CONFIGFILE | | Echo-n "Already Running"

}

D_stop () {

Kill-quit ' Cat $PIDFILE ' | | Echo-n "Not Running"

}

D_reload () {

Kill-hup ' Cat $PIDFILE ' | | Echo-n "can ' t reload"

}

Case "$" in

Start

Echo-n "Starting $DESC: $NAME"

D_start

echo "."

Stop

Echo-n "Stopping $DESC: $NAME"

D_stop

echo "."

Reload

Echo-n "Reloading $DESC configuration ..."

D_reload

echo "Reloaded."

;;

Restart

Echo-n "Restarting $DESC: $NAME"

D_stop

Sleep 1

D_start

echo "."

;;

echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2

Exit 3

;;

Esac

Exit 0

It feels like a githup account is needed to manage the configuration file.

Start Nginx

Write a test page for Tomcat, which is available in both formats (put in webapps/root/)

& nbsp <%= request.getsession (). GetId () %>

192.168.3.31

this is tomcat 1!

</center>

</body>

<%@ page contenttype= "Text/html;charset=utf-8" iselignored= "false"%>

Sessionid:<%=session.getid ()%><br>

Sessionip:<%=request.getservername ()%> <BR>

Sessionport:<%=request.getserverport ()%>

<% Out.println ("This isTomcat server!"); %>

Start Tomcat

Tomcat8+memcached Implementing session Sharing

Download the jar Package

Different versions of Tomcat use a jar package that may differ, this test uses tomcat-8.5.24

Jar Package Detail List and Tomcat (note: Jedis-2.9.0.jar is a jar bundle that connects to Redis)

Modify Conf/context.xml (per tomcat)

Here is Non-sticky sessions + Kryo, recommended reference official documentation: https://github.com/magro/memcached-session-manager/wiki/ Setupandconfiguration

<WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>

<manager classname= "De.javakaffee.web.msm.MemcachedBackupSessionManager"

memcachednodes="n1:192.168.3.31:11211"

Sticky= "false"

Sessionbackupasync= "false"

Lockingmode= "None"

Requesturiignorepattern= ". *\. (ICO|PNG|GIF|JPG|JPEG|CSS|JS) $ "

sessionbackuptimeout= "1000"

Transcoderfactoryclass= "De.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"

</Context>

Memcachednodes is the specified memcached, can have more than one node, N1 is a label, others by guessing

Start memcached, restart Tomcat

Access test

Using Redis instead of memcached

Inside the jar package, the Jedis-2.9.0.jar is the jar package that connects to Redis, the official explanation for details

Test failed (⊙﹏⊙) b

A bunch of incompatible versions of the problem, try all the jar packs with the latest results no

Error

Missing jar package or version conflict
