包括升级Nginx版本或者重新编译添加模块
如果忘记之前安装的配置参数
执行``nginx -V查看configure arguments`
1
| wget http://nginx.org/download/nginx-1.16.0.tar.gz
|
1
| yum -y install pcre-devel zlib-devel openssl-devel gcc gcc-c++ automake autoconf libtool make
|
1
| tar zxf nginx-1.16.0.tar.gz && cd nginx-1.16.0
|
比如重新编译添加支持fastdfs的模块

注意：不进行make install操作
make[1]: *** [/usr/local/openssl/.openssl/include/openssl/ssl.h] Error 127

编译安装 nginx 时，--with-openssl参数默认只支持OpenSSL的源代码，不支持已编译好的 OpenSSL。可以在nginx的解压目录下修改auto/lib/openssl/conf
1
| sed -i 's/\.openssl\///' auto/lib/openssl/conf
|
将文件中的.openssl去掉，就可以支持编译之后的openssl路径了
重新编译即可
1

3
| make clean
./configure ....
make
|
make完之后在objs目录下就多了个nginx，这个就是新版本的程序了
备份旧的Nginx程序
1
| cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
|
把新的Nginx程序覆盖旧的
1
| cp objs/nginx /usr/local/nginx/sbin/nginx
|
如果提示cp: cannot create regular file ‘/usr/local/nginx/sbin/nginx’: Text file busy
建议使用如下语句 cp
1
| cp -rfp objs/nginx /usr/local/nginx/sbin/nginx
|
测试新的Nginx程序是否正确
1
| /usr/local/nginx/sbin/nginx -t
|

平滑重启Nginx
1
| /usr/local/nginx/sbin/nginx -s reload
|
查看Nginx版本极其编译参数
1
| /usr/local/nginx/sbin/nginx -V
|
