CentOS安装openresty或者verynginx时:undefined reference to `pcre_free_study'，centosopenresty

一、openresty问题复现：centos安装openresty-1.11.2.5，./configure后make时报错：

很明显是pcre的问题，Google说是pcre版本问题；

解决办法：

1.下载新版本pcre，我下载的是pcre-8.38，解压，不需要安装；我服务器原版本是pcre-7.8.7

2.然后openresty目录下执行./configure时指定PCRE库的源码路径--with-pcre=/home/pcre-8.38

例：./configure --with-pcre=/home/pcre-8.38 (已省略其他编译参数，需要自行添加)

然后make，make install即可

 

二、安装verynginx时报同样错误

复现：python install.py install安装verynginx时,报同样错误;

解决：VeryNginx目录下install.py中大约51行处找到exec_sys_cmd( './configure --prefix=/opt/verynginx/openresty --user=nginx --group=nginx --with-http_v2_module --with-http_sub_module --with-http_stub_status_module --with-luajit ' )

后面同样加上--with-pcre=/home/pcre-8.38

即：exec_sys_cmd( './configure --prefix=/opt/verynginx/openresty --user=nginx --group=nginx --with-http_v2_module --with-http_sub_module --with-http_stub_status_module --with-luajit --with-pcre=/home/pcre-8.38' )

然后再执行python install.py install即可
