nginx添加块ngx_cache_purge编译失败

这几天折腾nginx然后遇到的的问题一一记录下来下次方便自查

上面编译的时候都会失败,是版本的原因我的是nginx1.14.0的版本 然后编译ngx_cache_purge-2.3以下的版本都会出现这种语法错误,然后我编译2.3的就ok

> ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --add-module=../ngx_cache_purge-2.3

sed -e "s|%%PREFIX%%|/usr/local/nginx|" \
    -e "s|%%PID_PATH%%|/usr/local/nginx/logs/nginx.pid|" \
    -e "s|%%CONF_PATH%%|/usr/local/nginx/conf/nginx.conf|" \
    -e "s|%%ERROR_LOG_PATH%%|/usr/local/nginx/logs/error.log|" \
    < man/nginx.8 > objs/nginx.8
make[1]: 离开目录“/usr/local/software/nginx-1.14.0”

上面就编译成功了

关于ngx_cache_purge的安装我是参照了几篇博客如果前面的步骤未完成同学可以试以下博主提供的方法
