Nginx安装配置

阅读更多

下面假设相关的软件及模块的压缩包都在/home/soft目录下:

1. 解压nginx

cd /home/soft
tar -zxvf nginx-1.2.0.tar.gz

2. 准备nginx_upstream_jvm_route模块的包

cd /nginx-1.2.0
patch -p0 < ../nginx_upstream_jvm_route/jvm_route.patch

3. 解压下载好的pcre包

cd ../
tar -zxvf pcre-8.31.tar.gz

 4.下面安装nginx

cd /nginx-1.2.0
./configure --prefix=/usr/local/nginx --with-pcre=/home/soft/pcre-8.31 --with-http_stub_status_module --with-http_ssl_module --add-module=/home/soft/nginx_upstream_jvm_route
make
make install

 5. 查看Nginx已安装/编译的模块

/usr/local/nginx/sbin/nginx -V

 6. 使用中发现某个模块（例如：http_realip_module）未安装？可以重新编译，然后复制objs/ngxin到nginx的sbin目录，替换原来的文件

重新编译并添加新模块(注意make后就不要make install了，不然就是覆盖安装了)

 

cd /nginx-1.2.0
./configure --prefix=/usr/local/nginx --with-pcre=/home/soft/pcre-8.31 --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --add-module=/home/soft/nginx_upstream_jvm_route
make

 

备份并替换原来的sbin/nginx文件

cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
cp ./objs/nginx /app/nginx/sbin/

 

7. 让nginx作为服务启动

vi /etc/init.d/nginx

 然后输入如下内容

#! /bin/sh

# description: Nginx Server
# chkconfig: 2345 99 01 
# source function library
. /etc/rc.d/init.d/functions

set -e

ulimit -SHn 51200
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="nginx daemon"
NAME=nginx
DAEMON=/usr/local/nginx/sbin/$NAME
CONFIGFILE=/usr/local/nginx/conf/nginx.conf
PIDFILE=/var/run/$NAME.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"
   killall nginx >/dev/null 2>1&
}

d_test() {
   $DAEMON -t
} 

d_reload() {
  kill -HUP `cat $PIDFILE` || echo -n " can't reload"
}

case "$1" in
  start)
  	echo -n "Starting $DESC: $NAME"
  	d_start
  	echo "."
	;;
  stop)
  	echo -n "Stopping $DESC: $NAME"
  	d_stop
  	echo "."
	;;
  test)
    d_test
    ;;
  reload)
  	echo -n "Reloading $DESC configuration..."
  	d_reload
  	echo "reloaded."
  ;;
  restart)
  	echo -n "Restarting $DESC: $NAME"
  	d_stop
  	# One second might not be time enough for a daemon to stop, 
  	# if this happens, d_start will fail (and dpkg will break if 
  	# the package is being upgraded). Change the timeout if needed
  	# be, or change d_stop to have start-stop-daemon use --retry. 
  	# Notice that using --retry slows down the shutdown process somewhat.
  	sleep 1 
  	d_start
  	echo "."
	;;
  *)
	  echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
	  exit 3
	;;
esac

exit 0

添加执行权限

chmod +x /etc/init.d/nginx

添加服务

chkconfig --add nginx
chkconfig nginx on

 启动/停止服务

service nginx start/stop

8. 启动失败

如下

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)

查看端口占用情况

netstat -ntpl

结束占用端口的进程，重新启动nginx
