chmod +x /etc/init.d/nginx

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

./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_gzip_static_module \
--with-http_flv_module \
--with-http_stub_status_module \
--with-http_v2_module \
--with-http_ssl_module \
--with-file-aio \
--with-http_realip_module \
--add-module=/root/fastdfs-nginx-module/src

注意:不进行make install操作

1
make

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

https://img.bwcxtech.com/img/20200928164756.png

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
