2.05 - Install Nginx-1.13.7 on Alibaba Cloud Esc server

1. Installation of Nginx

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

2. Installation environment configuration

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

3. Unzip: tar -zxvf nginx-1.13.7.tar.gz

4. Compile and install:

cd nginx-1.13.7 (that is, in the decompressed nginx file)

./configure compile

先 make 再 make install

5. Check the version: /usr/local/nginx/sbin/nginx -V

6. Start and restart:

/usr/local/nginx/sbin/nginx 启动

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

7. Access the Nginx server

http://localhost (i.e. Alibaba Cloud's public IP)

The success is as follows:

8. View progress and stop:

/usr/local/nginx/sbin/nginx -s stop Quick stop
/usr/local/nginx/sbin/nginx -s quit Complete stop
ps -ef | grep nginx View comprehensive process of all processes
kill -quit Main process number Stop process
kill -term main process number to quickly stop
kill -9 nginx forced stop

9. Add firewall exceptions

// Make port 80 a firewall exception

vim /etc/sysconfig/iptables

-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCERT added to the file

/etc/init.d/iptables restart restart the firewall

10. Nginx startup

1. Write a shell script

# 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. Set the access permissions of the file

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

3. Add to rc.local file

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

4. Set boot up

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 Differentiate different virtual hosts by port

1. Modify the nginx configuration file (ie /usr/local/nginx/conf/nginx.conf ) and add the following content

# 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. Restart the service

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

Differentiate different virtual hosts by domain name
Note that the domain name resolution rules:

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. On the local Windows computer, modify the C:\Windows\System32\drivers\etc\hosts file

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

2. In the server Centos7, modify the /usr/local/nginx/conf/nginx.conf file (add mm and pp directories under the corresponding path)

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. Restart the service to load the configuration file

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