这里安装的是nginx 1.14版本
1.下载源码
#下载
wget http://nginx.org/download/nginx-1.14.0.tar.gz
#解压
tar -xzf nginx-1.14.0.tar.gz
cd nginx-1.14.0
2.安装编译环境
yum update
yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
3.编译安装
#添加用户和组
groupadd www
useradd -g www www
#配置
./configure
--user=www
--group=www
--prefix=/usr/local/nginx
--with-http_ssl_module
--with-http_stub_status_module
--with-http_realip_module
--with-threads
#编译
make
#安装
make install
4.验证
/usr/local/nginx/sbin/nginx -V
输出如下：
nginx version: nginx/1.14.0
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-threads
5.创建软链接
ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
6.开机自启动
vim /etc/init.d/nginx
输入如下内容
#!/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: /usr/local/nginx/conf/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /usr/local/nginx/logs/nginx.pid
# Source function library.

[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/local/nginx/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/usr/local/nginx/conf/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
# make required directories
user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=([^ ]*).*/1/g' -`
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
}
start() {
[ -x $nginx ] || exit 5
[ -f $NGINX_CONF_FILE ] || exit 6
make_dirs
echo -n $"Starting $prog: "
daemon $nginx -c $NGINX_CONF_FILE
retval=$?
echo
[ $retval -eq 0 ] && touch $lockfile
return $retval
}
stop() {
echo -n $"Stopping $prog: "
killproc $prog -QUIT
retval=$?
echo
[ $retval -eq 0 ] && rm -f $lockfile
return $retval
}
restart() {
configtest || return $?
stop
sleep 1
start
}
reload() {
configtest || return $?
echo -n $"Reloading $prog: "
killproc $nginx -HUP
RETVAL=$?
echo
}
force_reload() {
restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
status $prog
}
rh_status_q() {
rh_status >/dev/null 2>&1
}
case "$1" in
start)
rh_status_q && exit 0

rh_status_q || exit 0
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
exit 2
esac
赋予脚本可执行权限
chmod a+x /etc/init.d/nginx
将nginx服务加入chkconfig管理列表
chkconfig --add /etc/init.d/nginx
chkconfig nginx on
# 启动
systemctl start nginx
7.测试
curl localhost:80
会有如下输出
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {
35em;
margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

<p><em>Thank you for using nginx.</em></p>

8.配置优化
下列配置在nginx.conf里与http节点同级
cd /usr/local/nginx/conf
vim nginx.conf
user www www;
worker_processes auto;
worker_rlimit_nofile 51200;
events
{
use epoll;
worker_connections 51200;
multi_accept on;
}
http节点下加入下列配置，将会从指定目录加载配置文件
include /etc/nginx/*.conf;
9.常用命令
# 启动
systemctl start nginx
# 查看状态
systemctl status nginx
# 停止
systemctl stop nginx
# 重载配置
nginx -s reload
# 测试配置是否正确
nginx -t
