nginx部署与安装

1、在学习ngnix的时候，免不了需要进行安装，安装其实很简单，一个shell脚本就可以搞定可以参考如下

使用root用户执行nginx-install.sh脚本即可，脚本如下：

#!/bin/bash
set -o nounset
basedir=$(cd "$(dirname "$0")"; pwd)

# 设置用户名和密码
sys_user=hadoop
sys_user_passwd=hadoop

# nginx 的版本信息
nginx_version=1.8.0

# nginx安装目录
nginx_install_dir=/usr/local/nginx

#检查gcc环境是否安装
which gcc &> /dev/null  || (echo -e "33[31mgcc uninstall !!33[0m"; exit 1)
test $? -eq 1 && exit 1

#
which make &>/dev/null || ( echo -e "33[31mmake uninstall!33[0m" ;exit 1)
test $? -eq 1 && exit 1

# check openssl 
openssl=$(rpm -qa | grep openssl)
if [[ $openssl = "" ]]
then
  echo -e "33[31mopenssl is uninstall33[0m"
  exit 1
fi

# check pcre-devel
pcre_devel=$(rpm -aq | grep pcre-devel)
if [[ $pcre_devel = "" ]]
then
  echo -e "33[31mpcre-devel is uninstall33[0m"
  exit 1
fi

# check zlib-devel
zlib_devel=$(rpm -aq | grep zlib-devel)
if [[ $zlib_devel = "" ]]
then 
  echo -e "33[31mzlib-devel is uninstall33[0m"
  exit 1
fi


test -f nginx-$nginx_version.tar.gz || (echo "nginx-$nginx_version.tar.gz file not found" ; exit 1)
test $? -eq 1 && exit 1

tar -zxf nginx-$nginx_version.tar.gz 
cd nginx-$nginx_version

./configure --prefix=$nginx_install_dir && make && make install || (echo "nginx install fail"; exit 1)
test $? -ge 1 && exit 1

function succ_msg {
  awk 'BEGIN{printf "%-50s 33[32m%-30s33[0m
","'$1'", "'$2'"}'
}

function fail_msg {
  awk 'BEGIN{printf "%-50s 33[31m33[05m%-30s33[0m
","'$1'", "'$2'"}'
}

succ_msg "nginx安装" "成功"

2、最终会提示安装成功，这个时候可以启动和检查nginx是否成功

　　启动nginx

/usr/local/nginx/sbin/nginx

nginx默认端口是80，查看服务是否重启成功
ps -ef | grep nginx

　关闭nginx

/usr/local/nginx/sbin/nginx -s stop

　　重新热启动命令

/usr/local/nginx/sbin/nginx -s reload

　　访问该服务器的ip，不需要加端口，出现如下说明安装部署成功
