This article mainly introduces the Linux platform through nginx and vsftpd method of building image server related knowledge, detailed and easy to understand, simple and fast operation, with a certain reference value, I believe that everyone reading this Linux platform through nginx and vsftpd method of building image server articles will have some gains, let's take a look at it.

First, nginx installation

1, nginx installation environment

Nginx is c language development, recommended to run on linux, this tutorial uses centos 6.5 as the installation environment.

To install nginx, you need to compile the source code downloaded from the official website first. The compilation depends on the gcc environment. If there is no gcc environment, you need to install gcc: yum install gcc-c++.

pcre(perlcompatible regular expressions) is a perl library that includes perl-compatible regular expressions libraries. The http module of nginx uses pcre to parse regular expressions, so you need to install the pcre library on linux.

yuminstall -y pcre pcre-devel

Note: pcre-devel is a secondary development library developed using pcre. Nginx also needs this library.

The zlib library provides many ways to compress and decompress. Nginx uses zlib to gzip the contents of http packages, so you need to install the zlib library on linux.

yuminstall -y zlib zlib-devel

Openssl is a powerful secure sockets layer cryptographic library that includes major cryptographic algorithms, common key and certificate encapsulation management functions, and ssl protocols, and provides a wealth of applications for testing and other purposes.

Nginx not only supports http protocol, but also https (that is, http over ssl protocol), so you need to install openssl library in linux.

yuminstall -y openssl openssl-devel

2. Compile and install

Copy nginx-1.8.0.tar.gz to your linux server.

Decompress:

tar -zxvf nginx-1.8.0.tar.gz

Enter the root directory of nginx:

cd nginx-1.8.0

a.configure

./ configure --help Query the detailed parameters (refer to the appendix section of this tutorial: nginx compilation parameters)

The parameters are set as follows:

./ configure \ --prefix=/usr/local/nginx \ --pid-path=/var/run/nginx/nginx.pid \ --lock-path=/var/lock/nginx.lock \ --error-log-path=/var/log/nginx/error.log \ --http-log-path=/var/log/nginx/access.log \ --with-http_gzip_static_module \ --http-client-body-temp-path=/var/temp/nginx/client\ --http-proxy-temp-path=/var/temp/nginx/proxy\ --http-fastcgi-temp-path=/var/temp/nginx/fastcgi\ --http-uwsgi-temp-path=/var/temp/nginx/uwsgi\ --http-scgi-temp-path=/var/temp/nginx/scgi

Note: Specify the temporary file directory as/var/temp/nginx at the top, and you need to create temp and nginx directories under/var

b. Compile and install

makemake install

Installation successful View installation directory:

c. Start nginx

cd /usr/local/nginx/sbin/./ nginx

Query nginx process:

15098 is the process id of the nginx main process, 15099 is the process id of the nginx worker process

Note: Implementation.../ nginx Start nginx, here you can specify the loaded nginx configuration file, as follows:

./ nginx-c /usr/local/nginx/conf/nginx.conf

If you do not specify-c, nginx loads the conf/nginx.conf file by default at startup, and the address of this file can also be specified when compiling and installing nginx./ configure parameters (--conf-path= points to configuration file (nginx.conf))

d. Stop nginx

Mode 1, Quick Stop:

cd /usr/local/nginx/sbin ./ nginx -s stop

This method is equivalent to finding out the nginx process id first and then using the kill command to forcibly kill the process.

Option 2, complete stop (recommended):

cd /usr/local/nginx/sbin ./ nginx -s quit

This method stops when the nginx process finishes processing tasks.

e. Restart nginx

Method 1, stop and start (recommended):

Rebooting nginx is equivalent to stopping nginx and then starting nginx, i.e. executing the stop command first and then the start command.

As follows:

./ nginx -s quit ./ nginx

Option 2: Reload the configuration file:

After the nginx configuration file nginx.conf is modified, you need to restart nginx to make the configuration take effect. Use-s reload to make the configuration information take effect in nginx without stopping nginx first and then starting nginx, as follows:

./ nginx -s reload

f. Testing

Nginx installation successful, start nginx, you can access nginx on the virtual machine:

This means that nginx was installed successfully.

II. FTP installation

1. Install vsftpd component

[root@bogon ~]# yum -y install vsftpd

After installation, there is the/etc/vsftpd/vsftpd.conf file, which is the configuration file for vsftp.

Add an FTP user

This user is used to log on to ftp servers.

[root@bogon ~]# useradd ftpuser

After such a user is created, you can log in with this, remember to log in with ordinary login instead of anonymous. The default path is/home/ftpuser.

Add a password to FTP users.

[root@bogon ~]# passwd ftpuser

Change password after entering password twice.

4. Firewall opens port 21

Because ftp default port is 21, and centos default is not open, so to modify the iptables file, some installed centos default does not open the firewall, then do not consider this step.

[root@bogon ~]# vim /etc/sysconfig/iptables

Enter something similar to that line below the 22 -jaccept line above, but replace 22 with 21, and then: wq save.

Also run, restart iptables

[root@bogon ~]# service iptables restart

5. Modify selinux

Extranet is accessible up, but found that can not return to the directory (active mode using ftp, passive mode or can not access), also can not upload, because selinux mischief.

Modify selinux:

Execute the following command to view the status:

[root@bogon ~]# getsebool -a | grepftp allow_ftpd_anon_write --> off allow_ftpd_full_access --> off allow_ftpd_use_cifs --> off allow_ftpd_use_nfs --> off ftp_home_dir --> off ftpd_connect_db --> off ftpd_use_passive_mode --> off httpd_enable_ftp_server --> off tftp_anon_write --> off [root@bogon ~]#

Execute the above command, and then return the result to see two lines are off, meaning that access to the external network is not enabled.

[root@bogon ~]#setsebool -p allow_ftpd_full_access on [root@bogon ~]#setsebool -p ftp_home_dir on

This should be no problem (if, or not, see if you use the ftp client tool with passive mode access, such as prompt entering passive mode, it means passive mode, the default is not good, because ftp passive mode is blocked by iptables, the following will talk about how to open, if lazy to open, then see if your client ftp port mode options, or remove the passive mode options. If the client still does not work, see if the host computer on the client has turned on the firewall, turn it off)

Filezilla active and passive mode modifications:

Menu: Edit → Settings

6. Turn off anonymous access

Modify the/etc/vsftpd/vsftpd.conf file:

Restart FTP service:

[root@bogon ~]# service vsftpd restart

7. Turn on passive mode

default is on, but to specify a port range, open the vsftpd.conf file, followed by

pasv_min_port=30000 pasv_max_port=30999

The port range is 30000~30999, which can be changed at will. Change and restart vsftpd

Since this port range is specified, iptables should also open this range accordingly, so open the iptables file as above.

Also start another line below 21, more similar line, just change 21 to 30000:30999, then:wq save, restart iptables. That's it.

8. Set boot to start vsftpd ftp service

[root@bogon ~]# chkconfig vsftpd on
