• 问题现象：编译安装完成之后，启动nginx报错

root@openwaf:/etc/nginx# /etc/init.d/nginx -t
/etc/init.d/nginx: error while loading shared libraries: libssl.so.1.1: cannot open shared object file: No such file or directory

• 解决办法：

root@openwaf:/etc/nginx# cp -p /usr/local/lib64/libssl.so.1.1 /usr/lib64/
root@openwaf:/etc/nginx# cp -p /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/

• 问题现象：报错如下图，原因可能是nginx配置中的用户不存在或者用户错误。

root@openwaf:/etc/nginx# /etc/init.d/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: [emerg] getpwnam("nginx") failed
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed　

• 解决方法： 

root@openwaf:/etc/nginx# cat /etc/nginx/nginx.conf |grep ^user
user  nginx;
root@openwaf:/etc/nginx# useradd -M -s /sbin/nologin nginx

问题现象：

root@openwaf:/opt# nginx -t -c /etc/ngx_openwaf.conf 
nginx: [emerg] unknown directive "lua_shared_dict" in /opt/OpenWAF/conf/twaf_main.conf:1

解决办法：可能是缺少nginx支持的开发库，lua-devel

root@openwaf:/opt# yum install lua-devel -y
root@openwaf:/opt# nginx -t 
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

总结：出现类似问题的优先考虑是否相应的开发库没有安装，或者nginx再编译的时候没有加相应的参数导致，都有可能。
