安装完Nginx后启动报错

安装完Nginx之后，启动报错。

[vagrant@localhost sbin]$ sudo ./nginx

./nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory

执行ldd命令，找到Nginx的依赖共享库文件。

vagrant@localhost sbin]$ ldd $(which /usr/local/nginx/sbin/nginx)

linux-vdso.so.1 =>  (0x00007fff1b74a000)

libpthread.so.0 => /lib64/libpthread.so.0 (0x00000032b2600000)

libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00000032b3a00000)

libpcre.so.1 => not found

libcrypto.so.6 => /lib64/libcrypto.so.6 (0x00000032b4200000)

libc.so.6 => /lib64/libc.so.6 (0x00000032b1a00000)

/lib64/ld-linux-x86-64.so.2 (0x00000032b1600000)

libdl.so.2 => /lib64/libdl.so.2 (0x00000032b1e00000)

libz.so.1 => /usr/lib64/libz.so.1 (0x00000032b3200000)

原来是真的没找到libpcre.so.1文件。

进入lib64目录，对libpcre.so.0.0.1做软连接。

[vagrant@localhost lib64]$ cd /lib64/

[vagrant@localhost lib64]$ sudo ln -s libpcre.so.0.0.1 libpcre.so.1

再次执行ldd命令，就可以找到libpcre.so.1依赖库了。

[vagrant@localhost lib64]$ ldd $(which /usr/local/nginx/sbin/nginx)

linux-vdso.so.1 =>  (0x00007fffd43d5000)

libpthread.so.0 => /lib64/libpthread.so.0 (0x00000032b2600000)

libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00000032b3a00000)

libpcre.so.1 => /lib64/libpcre.so.1 (0x00000032b1e00000)

libcrypto.so.6 => /lib64/libcrypto.so.6 (0x00000032b4200000)

libc.so.6 => /lib64/libc.so.6 (0x00000032b1a00000)

/lib64/ld-linux-x86-64.so.2 (0x00000032b1600000)

libdl.so.2 => /lib64/libdl.so.2 (0x00002aebb7623000)

libz.so.1 => /usr/lib64/libz.so.1 (0x00000032b3200000)

ok, 现在就可以成功启动Nginx。

[vagrant@localhost sbin]$ sudo ./nginx

[vagrant@localhost sbin]$ sudo netstat -ntlp | grep nginx
