Install nginx on centos

Download the latest nginxfile and install it at http://nginx.org/en/download.html.

1. download and install the PCRE LibraryFtp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/

Tar zxvf pcre-8.30.tar.gz./configure make install 2 install OpenSSL Yum-y install OpenSSL-devel 3 download tcp_proxy_module to https://github.com/yaoweibin/nginx_tcp_proxy_module download 4 install nginxexport nginx_version = 1.2.1curl-O uninstall-xvzf uninstall
CD nginx-$ nginx_version
Patch-P1 <../nginx_tcp_proxy_module/tcp. Patch
./Configure -- add-module = ../nginx_tcp_proxy_module/
Sudo make & make install

When nginx is started, the service cannot be started and the error libpcre. so.1 not found occurs. The solution is as follows:

Run the following command to view

--- # LDD $ (which/usr/sbin/nginx)

Shown as follows:

Linux-vdso.so.1 => (0x00007fff7e9db000)
Libpthread. so.0 =>/lib64/libpthread. so.0 (0x00007fe4629d0000)
Libcrypt. so.1 =>/lib64/libcrypt. so.1 (0x00007fe462799000)
Libpcre. so.1 => not found//Not Found
Libz. so.1 =>/lib64/libz. so.1 (0x00007fe462582000)
Libc. so.6 =>/lib64/libc. so.6 (0x00007fe4621e1000)
/Lib64/ld-linux-x86-64.so.2 (0x00007fe462bfa000)
Libfreebl3.so =>/lib64/libfreebl3.so (0x00007fe461f7e000)
Libdl. so.2 =>/lib64/libdl. so.2 (0x00007fe461d7a000)

Run the following command:

---- # Cd/lib64

---- # Ln-s libpcre. so.0.0.1 libpcre. so.1

Check again:

---- # LDD $ (which/usr/sbin/nginx)

It is OK:

Linux-vdso.so.1 => (0x00007fff4d7ff000)
Libpthread. so.0 =>/lib64/libpthread. so.0 (0x00007fb06f13e000)

Reverse Proxy web sockets with nginx and socket. iohttp: // www.letseehere.com/reverse-proxy-web-sockets

Possible Installation Problems

1. If you configure the parameters after./configure, the following error is prompted:

Objs/src/HTTP/modules/ngx_http_browser_module.o \

Objs/src/HTTP/modules/ngx_http_upstream_ip_hash_module.o \

Objs/src/HTTP/modules/ngx_http_upstream_least_conn_module.o \

Objs/src/HTTP/modules/ngx_http_upstream_keepalive_module.o \

Objs/ngx_modules.o \

-Lpthread-lcrypt-lpcre-lcrypto-LZ

Objs/src/CORE/ngx_regex.o: In function 'ngx _ pcre_free_studies ':

/Share/nginx-1.2.4/src/CORE/ngx_regex.c: 307: Undefined reference to 'pcre _ free_study'

Collect2: LD returned 1 exit status

Make [1]: *** [objs/nginx] Error 1

Make [1]: Leaving directory '/share/nginx-1.2.4'

Make: *** [Build] Error 2

Solution:

./Configure -- prefix =/usr/local/nginx -- without-http_autoindex_module -- without-http_geo_module -- without-http_map_module -- without-http_browser_module -- with-http_stub_status_module -- With-PCRE = ../with-http_realip_module

PS:./configure -- prefix =/usr/localnx -- without-http_autoindex_module -- without-http_geo_module -- With-PCRE = ../pcre-8.31

Note: Replace -- With-PCRE = ../pcre-8.31 with the path of your PCRE decompression package

2. If "-- with-http_gzip_static_module" (add gzip compression module) is added after "./configure", the following error is reported:

./Configure: error: the HTTP gzip module requires the zlib library.

You can either disable the module by using -- without-http_gzip_module

Option, or install the zlib library into the system, or build the zlib library

Statically from the source with nginx by using -- With-zlib = <path> option.

Solution: Install the zlib-devel package

# Yum-y install zlib-devel

Problems with starting nginx:

#/Usr/local/nginx/sbin/nginx

1./usr/local/nginx/sbin/nginx: Error while loading shared libraries: libpcre. so.1: cannot open shared object file: no such file or directory

The error indicates that the Lib file is missing. For more information, see

# LDD $ (which/usr/local/nginx/sbin/nginx)

Linux-gate.so.1 => (0x0071b000)

Libpthread. so.0 =>/lib/libpthread. so.0 (0 × 00498000)

Libcrypt. so.1 =>/lib/libcrypt. so.1 (0 × 00986000)

Libpcre. so.1 => not found

Libcrypto. so.6 =>/lib/libcrypto. so.6 (0 × 00196000)

Libz. so.1 =>/lib/libz. so.1 (0 × 00610000)

Libc. so.6 =>/lib/libc. so.6 (0x002d7000)

/Lib/ld-linux.so.2 (0x006a8000)

Libdl. so.2 =>/lib/libdl. so.2 (0x008c3000)

It can be seen that libpcre. so.1 => not found is not found. Go to the/lib directory and manually click

# Ln-s libpcre. so.0.0.1 libpcre. so.1

Then it is OK to start nginx.
