Error of nginx startup installation on centos6.0 Virtual Machine-libpcre. so.1 shared library missing

The virtual machine operating system is centos6.0 32-bit. After nginx1.2.0 is configured,

Run/usr/local/nginx/sbin/nginx

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 the shared library information:

# LDD/usr/local/nginx/sbin/nginx

Shown as follows:

Linux-gate.so.1 => (0x009a9000)
Libpthread. so.0 =>/lib/libpthread. so.0 (0x00e13000)
Libcrypt. so.1 =>/lib/libcrypt. so.1 (0x0027e000)
Libpcre. so.1 =>Not found
Libcrypto. so.10 =>/usr/lib/libcrypto. so.10 (0x002ae000)
Libz. so.1 =>/lib/libz. so.1 (0x00d54000)
Libc. so.6 =>/lib/libc. so.6 (0x005e9000)
/Lib/ld-linux.so.2 (0x00583000)
Libfreebl3.so =>/lib/libfreebl3.so (0x00110000)
Libdl. so.2 =>/lib/libdl. so.2 (0x008e9000)

Run the following command:

# Cd/lib

Because pcre8.3 has been installed in advance, I wonder why the library cannot be found. View the database location:

# Ll libpcre *

Lrwxrwxrwx. 1 Root 16 Apr 27 :42/lib/libpcre. so.0-> libpcre. so.0.0.1
-Rwxr-XR-X. 1 Root 190732 Aug 19 2010/lib/libpcre. so.0.0.1

The PCRE is in stock, but its name is not libpcre. so.1, but libpcre. so.0. Try to create a new link to solve this problem:

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

Check again:

# LDD/usr/local/nginx/sbin/nginx

It is OK:

Linux-gate.so.1 => (0x009a9000)
Libpthread. so.0 =>/lib/libpthread. so.0 (0x00e13000)
Libcrypt. so.1 =>/lib/libcrypt. so.1 (0x0027e000)
Libpcre. so.1 =>/lib/libpcre. so.1 (0x005b9000)
Libcrypto. so.10 =>/usr/lib/libcrypto. so.10 (0x002ae000)
Libz. so.1 =>/lib/libz. so.1 (0x00d54000)
Libc. so.6 =>/lib/libc. so.6 (0x005e9000)
/Lib/ld-linux.so.2 (0x00583000)
Libfreebl3.so =>/lib/libfreebl3.so (0x00110000)
Libdl. so.2 =>/lib/libdl. so.2 (0x008e9000)

Restart nginx:

/Usr/local/nginx/sbin/nginx-s reload

Started successfully! The homepage is displayed, and subsequent dynamic Tomcat content pages are displayed successfully.

If centos6 + 64-bit version is used, the module path is/lib64 instead of/lib.

It involves the dependency between modules in Linux. Although this method solves the problem, it does not know any side effects, and these dependencies are not mentioned in general information on the Internet. When you download and install PCRE, only the latest stable version 8.3 is available.
