在安装nginx前首先要确认系统中安装了gcc、pcre-devel、zlib-devel、openssl-devel。
- 安装make
yum -y install gcc automake autoconf libtool make
- 安装nginx需要的依赖包
yum install gcc gcc-c++
yum -y install gcc pcre-devel zlib-devel openssl openssl-devel
- 下载nginx(https://nginx.org/download/)
mkdir /usr/local/tools
cd /usr/local/tools
wget https://nginx.org/download/nginx-1.9.9.tar.gz
- 解压
tar -zxvf nginx-1.9.9.tar.gz
- 配置
#进入nginx目录
cd nginx-1.9.9
#配置安装路径
./configure --prefix=/usr/local/nginx
- 编译安装
make && make install
- 测试是否安装成功
#进入/usr/local/nginx/sbin/
cd /usr/local/nginx/sbin
./nginx -t
- 启动
./nginx

如果没有出现nginx首页，说明服务器的80端口是打不开的。
验证80端口
firewall-cmd --query-port=80/tcp

显然80端口没有开启。
开启80端口
# --permanent 永久生效，没有此参数重启后失效
firewall-cmd --add-port=80/tcp --permanent
#重启防火墙
systemctl restart firewalld

配置nginx开机自启动
首先，在linux系统的/etc/init.d/目录下创建nginx.service文件，使用如下命令：
vim /etc/init.d/nginx.service
在脚本中添加如下命令：
#!/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
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories

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
}

脚本参考：http://wiki.nginx.org/RedHatNginxInitScript
需要根据您的安装路径修改下面这两项配置：
nginx="/usr/local/nginx/sbin/nginx" 修改成nginx执行程序的路径。
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf" 修改成配置文件的路径。
保存脚本文件后设置文件的执行权限：
chmod a+x /etc/init.d/nginx.service
使用chkconfig进行管理
chkconfig --add /etc/init.d/nginx.service
设置终端模式开机启动：
chkconfig nginx.service on
