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

安装nginx

#解压nginx
tar -zxvf nginx-1.12.0.tar.gz
#安装nginx
cd nginx-1.12.0

ln -s  /usr/local/nginx/sbin/nginx /usr/sbin/

./configure配置的时将如下配置与/etc/init.d/nginx文件中保持一致

# config:      /etc/nginx/nginx.conf
# pidfile:     /var/run/nginx.pid
nginx="/usr/sbin/nginx"
NGINX_CONF_FILE="/etc/nginx/nginx.conf"

3、配置服务

在/etc/init.d/目录下创建nginx文件。
nginx官方写nginx官方写的脚本。
https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  NGINX is an HTTP(S) server, HTTP(S) reverse 
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/nginx.pid

# Source function library.
. /etc/rc.d/init.d/functions

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

nginx="/usr/sbin/nginx"
prog=$(basename $nginx)

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx

lockfile=/var/lock/subsys/nginx

make_dirs() {

   if [ -n "$user" ]; then
      if [ -z "`grep $user /etc/passwd`" ]; then
         useradd -M -s /bin/nologin $user
      fi
      options=`$nginx -V 2>&1 | grep 'configure arguments:'`
      for opt in $options; do
          if [ `echo $opt | grep '.*-temp-path'` ]; then
              value=`echo $opt | cut -d "=" -f 2`
              if [ ! -d "$value" ]; then
                  # echo "creating" $value
                  mkdir -p $value && chown -R $user $value
              fi
          fi
       done

        exit 2
esac

#设置文件的执行权限
chmod a+x /etc/init.d/nginx
#设置开机启动
chkconfig nginx on

4、启动测试

#启动查看
service nginx start
ps -ef|grep nginx
curl http://127.0.0.1
