nginx安装配置+集群tomcat：Centos和windows环境

版本：nginx-1.8.0.tar.gz

官网：http://nginx.org/en/download.html

版本：apache-tomcat-6.0.44.tar.gz

官网：http://tomcat.apache.org/

1、安装脚本：

# yum clean all

# yum makecache

# yum update

# yum install wget

# wget -c http://nginx.org/download/nginx-1.7.9.tar.gz

# find -name nginx

# yum remove nginx

# cd /下载目录

# tar -zxv -f nginx-1.7.9.tar.gz

# rm -rf nginx-1.7.9.tar.gz

# mv nginx-1.7.9  /usr/local/nginx

# yum install gcc-c++
# yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel

# cd /usr/local/nginx

# ./configure --prefix=/usr/local/nginx --conf-path=/usr/local/nginx/nginx.conf

# make && make install

2、启动/重启/停止/

启动：# /usr/local/nginx/sbin/nginx

重启：# /usr/local/nginx/sbin/nginx -s reload

停止：

#查询nginx主进程号 ：ps -ef | grep nginx

#停止进程 ：kill -QUIT 主进程号 
#快速停止 ：kill -TERM 主进程号 
#强制停止 ：pkill -9 nginx

3、开机启动，启动脚本

2、更改脚本权限：chmod 775 /etc/init.d/nginx

或：chmod a+x /etc/init.d/nginx     (a+x ==> all user can execute 所有用户可执行)

3、编写脚本内容：

#!/bin/bash

# nginx Startup script for the Nginx HTTP Server

# it is v.0.0.2 version.

# chkconfig: - 85 15

# description: Nginx is a high-performance web and proxy server.

#              It has a lot of features, but it‘s not for everyone.

# processname: nginx

# pidfile: /var/run/nginx.pid

# config: /usr/local/nginx/conf/nginx.conf

nginxd=/usr/local/nginx/sbin/nginx

nginx_config=/usr/local/nginx/conf/nginx.conf

nginx_pid=/var/run/nginx.pid

[ ${NETWORKING} = "no" ] && exit 0

[ -x $nginxd ] || exit 0

# Start nginx daemons functions.

start() {

if [ -e $nginx_pid ];then

echo "nginx already running...."

exit 1

fi

echo -n $"Starting $prog: "

daemon $nginxd -c ${nginx_config}

RETVAL=$?

echo

[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx

return $RETVAL

}

# Stop nginx daemons functions.

stop() {

echo -n $"Stopping $prog: "

killproc $nginxd

RETVAL=$?

echo

[ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /var/run/nginx.pid

}

# reload nginx service functions.

reload() {

echo -n $"Reloading $prog: "

#kill -HUP `cat ${nginx_pid}`

killproc $nginxd -HUP

RETVAL=$?

echo

# See how we were called.

4、设置开机启动：chkconfig nginx on

或：vi /etc/rc.local 加入一行 /etc/init.d/nginx start 保存并退出，下次重启会生效。

5、这样在控制台就很容易的操作nginx了：查看Nginx当前状态、启动Nginx、停止Nginx、重启Nginx…

/etc/init.d/nginx status

/etc/init.d/nginx start

/etc/init.d/nginx stop

/etc/init.d/nginx restart

4、nginx负载均衡配置：集群tomcat

windows下直接解压，点击nginx.exe即可启动，常用命令如下(.exe可去掉)【此为后台运行方式；windows下nginx不自己注册系统服务，需要依赖第三方工具处理注册表信息比较复杂；】：

cd nginx目录下；

启动：nginx.exe 或双击

停止：nginx.exe -s stop

重新加载：nginx.exe -s reload

退出：nginx.exe -s quit;
