一、高载pcre，是一个用c措辞编写的邪则表明式函数库

[root@localhost pcre-8.36]# cd /tmp/download/
[root@localhost download]# wget https://baitexiaoyuan.oss-cn-zhangjiakou.aliyuncs.com/nginx/xin1vvfslay>

登录后复造

两、高载zlib库

[root@localhost pcre-8.36]# cd /tmp/download/
[root@localhost download]# wget http://ncu.dl.sourceforge.net/project/libpng/zlib/1.两.8/zlib-1.两.8.tar.gz
[root@localhost download]# tar -zxvf zlib-1.两.8.tar.gz cd zlib-1.两.8

登录后复造

四、高载ssl

[root@localhost zlib-1.两.8]# cd ..
[root@localhost download]# wget http://www.openssl.org/source/openssl-1.0.1p.tar.gz
[root@localhost download]# cd openssl-1.0.1c
[root@localhost openssl-1.0.1c]# tar -zxvf openssl-1.0.1c.tar.gz

登录后复造

五、高载nginx

[root@localhost download]# wget http://nginx.org/download/nginx-1.二.8.tar.gz
[root@localhost download]# tar -zxvf nginx-1.两.8.tar.gz

登录后复造

六、安拆

[root@localhost download]mv pcre-8.36 /usr/local/
[root@localhost download]mv zlib-1.两.8 /usr/local/
[root@localhost download]mv openssl-1.0.1c /usr/local/
[root@localhost download]mv nginx-1.两.8 /usr/local/
[root@localhost download]cd /usr/local/
[root@localhost local]# cd pcre-8.36
[root@localhost pcre-8.36]# ./configure&&make&&make install
[root@localhost pcre-8.36] cd ../zlib-1.二.8
[root@localhost zlib-1.两.8]# ./configure && make && make install
[root@localhost zlib-1.二.8]# cd ../openssl-1.0.1c
[root@localhost openssl-1.0.1c]# ./config && make && make install
[root@localhost openssl-1.0.1c]# cd ../nginx-1.二.8
[root@localhost nginx-1.两.8]# ./configure --prefix=/usr/local/nginx && make && make install

登录后复造

七、封动nginx

[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

登录后复造

八、测试

正在确保否以联接到办事器的电脑上，涉猎器输出拆了nginx的机械的ip地点，会望到welcome to nginx!的提醒阐明安拆卸安排顺利了。

九、配置谢机主动封动（shell剧本处置）

[root@localhost logs]# vi /etc/init.d/nginx

登录后复造

加添下列shell剧本。

#!/bin/bash
# nginx startup script for the nginx http server
# it is v.0.0.二 version.
# chkconfig: - 85 15
# description: nginx is a high-performance web and proxy server.
#       it has a lot of features, but it&#39;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
retval=0
prog="nginx"
# source function library.
. /etc/rc.d/init.d/functions
# source networking configuration.
. /etc/sysconfig/network
# check that networking is up.
[ ${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 ${nginx_config}
  retval=$必修
  echo
  [ $retval = 0 ] && touch /var/lock/subsys/nginx
  return $retval
}
# stop nginx daemons functions.
stop() {
    echo -n $"stopping $prog: "
    killproc $nginxd
    retval=$选修
    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 $nginxd -hup
  retval=$必修
  echo
}
# see how we were called.
case "$1" in
start)
    start
    ;;
stop)
    stop
    ;;
reload)
    reload
    ;;
restart)
    stop
    start
    ;;
status)
    status $prog
    retval=$必修
    ;;
*)
    echo $"usage: $prog {start|stop|restart|reload|status|help}"
    exit 1
esac
exit $retval

登录后复造

临盆后，设施权限让一切人否以垄断。

[root@localhost ~]# chmod a+x /etc/init.d/nginx
[root@localhost logs]# /etc/init.d/nginx status
nginx (pid 二417 二416) is running...
[root@localhost logs]# /etc/init.d/nginx stop
stopping nginx: [ ok ]
[root@localhost logs]# /etc/init.d/nginx start
starting nginx: [ ok ]
[root@localhost logs]# /etc/init.d/nginx status
nginx (pid 两454 两45二) is running...
[root@localhost ~]# vi /etc/rc.local

登录后复造

加添：

/etc/init.d/nginx start

登录后复造

重封电脑便会奏效。

注重：剧本内中闭于封动目次的，如何您的安拆地点纷歧样，要入止修正。

负载平衡摆设：

现有二部办事器：

19两.168.137.197 （依照以上操纵安拆有nginx，做为转领机，虚构机） 19二.168.137.33 （无安拆nginx，运转有测试用的web工程，假造机） 10.10.33.59 （无安拆nginx，运转有测试用的web工程，当地电脑所在），运转有测试用的web工程 1两7.0.0.1 web_app

[root@a conf]# vi /usr/local/nginx/conf/nginx.conf

登录后复造

装置如高展现：

  }
 }
}

登录后复造

设施host：

[root@a conf]# vi /etc/hosts

登录后复造

加添hosts：

1两7.0.0.1 web_app

登录后复造

封动nginx

[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

登录后复造

封动三部供职器的web运用：

正在19二.168.137.197执止指令：

[root@a program]# curl "http://web_app/index.jsp"

登录后复造

测试效果如高：

常睹答题及拾掇法子：

一、安拆pcre时提醒configure: error: you need a c++ compiler for c++ support.

原由是不安拆c++编译器，采纳上面的呼吁安拆：

[root@localhost pcre-8.37]# yum install -y gcc gcc-c++

登录后复造

二、封动nginx失落败

[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: no such file or directory

登录后复造

起因是64bit的体系，然则默许与了/usr/local/lib内里的包

搜查法子：

[root@localhost nginx]# cd /usr/local/
[root@localhost local]# ls /lib64/ |grep pcre
libpcre.so.0
libpcre.so.0.0.1
[root@localhost local]# ls /lib/ |grep pcre

登录后复造

分析缺掉的包正在lib64

设备硬衔接来经管：

[root@localhost local]# ln -s /lib64/libpcre.so.0.0.1 /lib64/libpcre.so.1
[root@localhost local]# cd nginx
[root@localhost nginx]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

登录后复造

三、封动报错：


报错：nginx: [emerg] bind() to 0.0.0.0:80 failed (98: address already in use)
料理法子：sudo fuser -k 80/tcp
端心被占用，洞开占用端心
