1. Install pcre

In order to support the rewrite function, we need to install pcre.

The copy code code is as follows:

# yum install pcre* // If it is already installed, please skip this step.

Install openssl

Ssl support is required. If ssl support is not required, please skip this step.

The copy code code is as follows:

# yum installing openssl*

3.gzip class library installation

The copy code code is as follows:

Yum installs zlib zlib-devel

Install wget

Download nginx for use. If already installed, please skip this step.

The copy code code is as follows:

# yum install wget

Second, install nginx.

1.[ meter]

The copy code code is as follows:

wget

nginx.com。

Close:

The copy code code is as follows:

/usr/local/nginx- 1 . 7 . 0/sbin/nginx-s stop

Reset: When modifying the configuration file, just reload it below.

The copy code code is as follows:

/usr/local/nginx-1.7.0/sbin/nginx-s reload.

This is the end of the entire nginx installation.

If the options are set at the server level, they will take effect before positioning. If there are further rewriting rules in location, some rules in location will still be implemented. If this URI rewriting is caused by the rules of the location part, then the location part will be executed again as a new URI.

–-without-mail _ pop 3 _ module disables the POP3 protocol (POP3 is the third version of post office protocol, which is a protocol that specifies how a personal computer connects to a mail server on the Internet to send and receive mail. It is the first offline protocol standard for Internet e-mail. POP3 protocol allows users to store mail from the server to the local host, and at the same time delete or save the mail on the mail server according to the operation of the client. POP3 protocol is a member of TCP/IP protocol family, which is mainly used to support the remote management of e-mail on the server using the client.

–Without -mail _ imap _ module, imap protocol (a mail acquisition protocol) will be disabled. Its main function is that the mail client can obtain the information of the mail from the mail server and download the mail through this protocol. IMAP protocol runs on top of TCP/IP protocol, and the port used is 143. The main difference between it and POP3 protocol is that users can directly operate the mail on the server through the client without downloading all the mail. )

–-without-mail _ smtp _ module disables SMTP protocol (SMTP is a simple mail transmission protocol, which is a set of rules for sending mail from source address to destination address, and it controls the transmission mode of letters.
