Linux/centos installation Nginx common errors and solutions

1. Can not be accessed after installation is complete Nginx?

Just installed Nginx A common problem is unable to stand outside the access, native wget, Telnet are normal. Outside the server, the site is inaccessible to other hosts on the LAN or to hosts on the Internet. If using Telnet, prompt:

Connecting to 192.168.0.xxx ... Cannot open connection to host on port 80: Connection Failed

If you use the wget command, prompt:

Connecting to 192.168.0.100:80 ... Failed:no route to host.

If it is the above phenomenon, it is likely that the CentOS firewall to the 80 port stopped, try to execute the following command, open 80 port:

Iptables-i input-p TCP--dport 80-j ACCEPT

Then use:

/etc/init.d/iptables status

Review the current firewall rules, if one is found:

ACCEPT TCP--0.0.0.0/0 0.0.0.0/0 TCP dpt:80

This means that the firewall rules have been added successfully, and then access outside the station is normal.

2. Compile Pcre error (source installation Nginx must first install pcre)

libtool:compile:unrecognized option '-dhave_config_h '

Libtool:compile:Try ' Libtool--help ' for more information.

MAKE[1]: * * * [Pcrecpp.lo] Error 1

MAKE[1]: Leaving directory '/usr/local/src/pcre-8.21 '

Make: * * * [ALL] Error 2

Workaround: Install g++, don't forget to re-configure

Apt-get Install g++

Apt-get Install Build-essential

Make clean

./configure

Make

3. Make error

Make: * * * No rule to do target ' build ', needed by ' default '. Stop.

./CONFIGURE:ERROR:SSL modules require the OpenSSL library.

You can either does not enable the modules, or install the OpenSSL library

Into the system, or build the OpenSSL library statically from the source

With Nginx by using--with-openssl=<path> option.

Solutions under Ubuntu:

Apt-get Install OpenSSL

Apt-get Install Libssl-dev

Solutions under CentOS:

Yum-y Install OpenSSL Openssl-devel

4. Dependent software Prce,ssl,zlib not installed error
