51工具盒子在编译nginx时，默认会以debug模式来运行，取消debug的好处是编译后的nginx更加小巧，编译更快。
1、下载nginx源码包
wget http://nginx.org/download/nginx-1.14.0.tar.gz
|---|----------------------------------------------------| | 1 | wget http://nginx.org/download/nginx-1.14.0.tar.gz |
2、解压缩后编辑auto/cc/gcc文件
vi nginx-1.14.0/auto/cc/gcc
|---|-----------------------------| | 1 | vi nginx-1.14.0/auto/cc/gcc |
删除其中两行
debug CFLAGS="$CFLAGS -g"
|-----|-----------------------------| | 1 2 | # debug CFLAGS="$CFLAGS -g" |
3、安装依赖并创建nginx启动用户
yum install wget gcc gcc-c++ pcre pcre-devel openssl openssl-devel zlib zlib-devel useradd -s /bin/false -M www
|-----|-----------------------------------------------------------------------------------------------------------------| | 1 2 | yum install wget gcc gcc-c++ pcre pcre-devel openssl openssl-devel zlib zlib-devel useradd -s /bin/false -M www |
4、正式开始编译nginx
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module --with-http_gzip_static_module --with-http_sub_module make make install
|-------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 | ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module --with-http_gzip_static_module --with-http_sub_module make make install |
5、设置软链接
ln -sv /usr/local/nginx/sbin/nginx /usr/local/sbin/
|---|-----------------------------------------------------| | 1 | ln -sv /usr/local/nginx/sbin/nginx /usr/local/sbin/ |
6、设置systemctl
vi /usr/lib/systemd/system/nginx.service
|---|------------------------------------------| | 1 | vi /usr/lib/systemd/system/nginx.service |
[Unit] Description=nginx After=network.target [Service] Type=forking PIDFile=/usr/local/nginx/logs/nginx.pid ExecStart=/usr/local/nginx/sbin/nginx ExecReload=/usr/local/nginx/sbin/nginx -s reload ExecStop=/usr/local/nginx/sbin/nginx -s stop PrivateTmp=true [Install] WantedBy=multi-user.target
|----------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | 1 2 3 4 5 6 7 8 9 10 11 12 | [Unit] Description=nginx After=network.target [Service] Type=forking PIDFile=/usr/local/nginx/logs/nginx.pid ExecStart=/usr/local/nginx/sbin/nginx ExecReload=/usr/local/nginx/sbin/nginx -s reload ExecStop=/usr/local/nginx/sbin/nginx -s stop PrivateTmp=true [Install] WantedBy=multi-user.target |
7、启动nginx并设置开机自启
systemctl start nginx systemctl enable nginx
|-----|----------------------------------------------| | 1 2 | systemctl start nginx systemctl enable nginx |
8、结语
同样的编译参数，在没有取消debug模式前，编译后的nginx大小12M，取消后nginx的大小为1000K。
