最近在学习nginx,nginx rewrite依赖于PCRE库,所以需要在linux系统中编译安装PCRE库。具体步骤如下:
1.下载PCRE包
首先去官网下载pcre的安装包
如果通过FTP的方式,下载地址为:ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
如果通过http的方式,下载地址为:http://sourceforge.net/projects/pcre/files/pcre/
目前最新的版本为8.32,linux对应的安装包名称为:pcre-8.32.tar.gz。
2.把安装包上传到服务器,然后解压
[root@localhost local]# tar -zxvf pcre-8.32.tar.gz
解压之后在当前目录下生成了一个文件夹:pcre-8.32
drwxr-xr-x 7 1169 1169 4096 Nov 30 18:50 pcre-8.32
3.配置
[root@localhost pcre-8.32]# ./configure
配置完之后控制台会打印出pcre配置的摘要信息
pcre-8.32 configuration summary: Install prefix .................. : /usr/local C preprocessor .................. : gcc -E C compiler ...................... : gcc C++ preprocessor ................ : g++ -E C++ compiler .................... : g++ Linker .......................... : /usr/bin/ld C preprocessor flags ............ : C compiler flags ................ : -O2 -fvisibility=hidden C++ compiler flags .............. : -O2 -fvisibility=hidden -fvisibility-inlines-hidden Linker flags .................... : Extra libraries ................. : Build 8 bit pcre library ........ : yes Build 16 bit pcre library ....... : no Build 32 bit pcre library ....... : no Build C++ library ............... : yes Enable JIT compiling support .... : no Enable UTF-8/16/32 support ...... : no Unicode properties .............. : no Newline char/sequence ........... : lf \R matches only ANYCRLF ......... : no EBCDIC coding ................... : no EBCDIC code for NL .............. : n/a Rebuild char tables ............. : no Use stack recursion ............. : yes POSIX mem threshold ............. : 10 Internal link size .............. : 2 Match limit ..................... : 10000000 Match limit recursion ........... : MATCH_LIMIT Build shared libs ............... : yes Build static libs ............... : yes Use JIT in pcregrep ............. : no Buffer size for pcregrep ........ : 20480 Link pcregrep with libz ......... : no Link pcregrep with libbz2 ....... : no Link pcretest with libedit ...... : no Link pcretest with libreadline .. : no Valgrind support ................ : no Code coverage ................... : no
4.编译
执行make操作:
[root@localhost pcre-8.32]# make
编译完后可以执行make check进行测试(这一步非必须)
Testing pcregrep version 8.32 2012-11-30 Testing pcregrep main features Skipping pcregrep UTF-8 tests: no UTF-8 support in PCRE library Testing pcregrep newline settings PASS: RunGrepTest ================== All 5 tests passed ================== make[2]: Leaving directory `/usr/local/pcre-8.32' make[1]: Leaving directory `/usr/local/pcre-8.32' [root@localhost pcre-8.32]#
上面的make check结果中有一句:
Skipping pcregrep UTF-8 tests: no UTF-8 support in PCRE library
这是因为在前面步骤中执行./configuration配置时没有加上对utf-8的支持
如果要加上对utf-8的支持可以在./configuration时加上参数:
[root@localhost pcre-8.32]# ./configure --enable-utf8
配置完后再重新make
make完后再次执行make check结果如下:
Testing pcregrep version 8.32 2012-11-30 Testing pcregrep main features Testing pcregrep UTF-8 features Testing pcregrep newline settings PASS: RunGrepTest ================== All 5 tests passed ================== make[2]: Leaving directory `/usr/local/pcre-8.32' make[1]: Leaving directory `/usr/local/pcre-8.32' [root@localhost pcre-8.32]#
5.安装
执行make install操作:
[root@localhost pcre-8.32]# make install
make install结束后pcre编译安装流程就结束了。
