需求描述:
公司的在线系统前端页面上了CDN,但是无法对 wasm 文件进行压缩优化,这种文件很大加载慢影响用户体验
需要对 wasm 进行压缩后访问,但是需要nginx支持 ngx_brotli  模块才行

模块的github地址
https://github.com/google/ngx_brotli

# -q 是压缩级别
brotli -q 5 -f FicModule.wasm

准备工作:
# 编译安装 ngx_brotli,需要重新编译nginx,此处我们使用的是tengine2.3.2版本
1.安装依赖

yum -y install git

mkdir /usr/local/ngx_module
cd /usr/local/ngx_module/
git clone https://github.com/google/ngx_brotli.git

cd ngx_brotli/
# 国内因为网络问题,无法正常下载deps里面的文件,需要FQ下载后拷贝过来
git submodule update --init

2.重新编译tengine2.3.2

cd /usr/local/src/tengine-2.3.2
# 更换编译目标路径为 /usr/local/tengine-2.3.2_with_brotli,避免和现有的nginx冲突

# 编译过程

./configure --prefix=/usr/local/tengine-2.3.2_with_brotli --with-ld-opt="-Wl,-rpath,/usr/local/include/luajit2.1/lib" --user=daemon --group=daemon --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_sub_module --with-http_stub_status_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gzip_static_module --with-http_geoip_module --with-http_secure_link_module --with-http_degradation_module --with-mail_ssl_module --with-pcre=/usr/local/lab/pcre-8.34 --with-zlib=/usr/local/lab/zlib-1.2.11 --add-module=/usr/local/lab/ngx_cache_purge-2.3 --with-jemalloc --with-http_lua_module --with-luajit-lib=/usr/local/include/luajit2.1/lib --with-luajit-inc=/usr/local/include/luajit2.1/include/luajit-2.1/ --with-lua-inc=/usr/local/include/luajit2.1/include/luajit-2.1/ --with-lua-lib=/usr/local/include/luajit2.1/lib --with-openssl=/usr/local/lab/openssl-1.1.0l --add-module=/usr/local/ngx_http_geoip2_module-3.2 --with-stream --add-module=/usr/local/lab/nginx_upstream_check_module-master --add-module=/usr/local/ngx_module/ngx_brotli
