2.05—阿里云Esc服务器安装Nginx-1.13.7

一、Nginx的安装

1.下载 ： wget http://nginx.org/download/nginx-1.13.7.tar.gz

2.安装环境配置

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

3.解压 ： tar -zxvf nginx-1.13.7.tar.gz

4.编译和安装：

cd nginx-1.13.7 (即解压后的nginx文件中)

./configure 编译

先 make 再 make install

5. 查看版本 ：/usr/local/nginx/sbin/nginx -V

6. 启动与重启 ：

/usr/local/nginx/sbin/nginx 启动

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

7. 访问Nginx服务器

http：//localhost（即阿里云的公有IP）

成功如下图：



8. 查看进程与停止：

/usr/local/nginx/sbin/nginx -s stop 快速停止
/usr/local/nginx/sbin/nginx -s quit 完整停止
ps -ef | grep nginx 查看所有进程的全面进程
kill -quit 主进程号 停止进程
kill -term 主进程号 快速停止
kill -9 nginx 强制停止

9. 添加防火墙例外

// 将80端口为防火墙例外

vim /etc/sysconfig/iptables

-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCERT 新增到文件中

/etc/init.d/iptables restart 重启防火墙

10. Nginx开机启动

1. 编写shell脚本

# 添加修改此文件：vi /etc/init.d/nginx
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
#              It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf
# 注意下面的两行要修改成你的实际路径
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 ${nginx_config}
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
return $RETVAL
}
# Stop nginx daemons functions.
stop() {
echo -n $"Stopping $prog: "
killproc $nginxd
RETVAL=$?
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 $nginxd -HUP
RETVAL=$?
echo
}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
stop
start
;;
status)
status $prog
RETVAL=$?
;;
*)
echo $"Usage: $prog {start|stop|restart|reload|status|help}"
exit 1
esac
exit $RETVAL

2.设置文件的访问权限

chmod a+x /etc/init.d/nginx

3. 加入到rc.local文件中

# 修改vi /etc/rc.local，添加如下内容
/etc/init.d/nginx start

4. 设置开机启动

chkconfig --add nginx #添加系统服务
chkconfig --level 345 nginx on #设置开机启动,启动级别
chkconfig --list nginx #查看开机启动配置信息

11 通过端口区分不同的虚拟主机

1.修改nginx的配置文件（即 /usr/local/nginx/conf/nginx.conf ），添加以下内容

# 在配置文件中添加server节点：写入多份server节点，其端口号不同来区分虚拟主机
server {
listen       80;
server_name  localhost;

location / {
root   html;
index  index.html index.htm;
}
}
server {
listen       81;
server_name  localhost;

location / {
root   html81;
index  index.html index.htm;
}
}

2.重启服务

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

通过域名区分不同的虚拟主机

注意，域名解析规则：

一个域名对应一个IP地址，一个IP地址可以被多个域名绑定

1. 本地windows电脑，修改 C:\Windows\System32\drivers\etc\hosts文件

192.168.31.117       manager.dhc.com
192.168.31.117       portal.dhc.com

2. 服务器Centos7中，修改/usr/local/nginx/conf/nginx.conf文件（在对应路径下添加mm和pp目录即可）

server {
listen       80;
server_name  manager.dhc.com;

location / {
root   mm;
index  index.html index.htm;
}
}

server {
listen       80;
server_name  portal.dhc.com;

location / {
root   pp;
index  index.html index.htm;
}
}

3. 重启服务加载配置文件

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