Nginx startup error: error while loading shared libraries: libpcreso1

1	# /usr/local/nginx/sbin/nginx

2	/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such fileor directory

It can be seen from the error message that it is caused by the lack of lib files. Further check the specific content:

1	# ldd $(which /usr/local/nginx/sbin/nginx)

2	libpthread.so.0 => /lib64/libpthread.so.0 (0x00000030e8400000)

3	libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00000030f9a00000)

4	libpcre.so.1 => not found

5	libcrypto.so.6 => /lib64/libcrypto.so.6 (0x00000030f2a00000)

6	libz.so.1 => /lib64/libz.so.1 (0x00000030e8800000)

7	libc.so.6 => /lib64/libc.so.6 (0x00000030e7800000)

8	/lib64/ld-linux- x86-64.so.2 (0x00000030e7400000)

9	libdl.so.2 => /lib64/libdl.so.2 (0x00000030e8000000)

View the results: libpcre.so.1 => not found ,Also pay attention to the path of the lib library, there is / lib/* and /lib64/* .

For example, the above is /lib64/*,This is related to the soft connection created when solving the problem below

Solution:

1. First, confirm that the pcre software has been installed (nginx depends on this software)

2. Create a soft connection

For /lib/* 32-bit system:

1	#View lib library

2	# ls /lib/ |grep pcre

3	libpcre.so.0

4	libpcre.so. 0.0.1

5	#Add soft link

6	# ln -s /lib/libpcre.so.0.0.1 /lib/libpcre.so.1

ps: It is also possible that the pcre lib file is in the directory: /usr/local/lib/

For /lib64/* 64-bit systems:

1	#View lib library

2	# ls /lib64/ |grep pcre

3	libpcre.so.0

4	libpcre. so.0.0.1

5	#Add soft connection

6	# ln -s /lib64/libpcre.so.0.0.1/lib64/libpcre.so.1

ps: The pcre lib file is in Directory: /usr/local/lib64/.

The above introduces the Nginx startup error: error while loading shared libraries: libpcreso1, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
