无论是否启用了这些修补程序，我都会对服务器A和B的测试结果做一个额外说明。

在我的家用PC上，补丁级别从未更改。

LAppS依赖于luajit-2.0.5或更高版本，libcrypto ++ 8.2和wolfSSL-3.15.7库，它们必须从RHEL 7.6以及可能的任何其他Linux发行版中的源安装。

安装的前缀是/ usr / local。 这是WolfSSL安装的几乎不言自明的Dockerfile部分

 ADD https://github.com/wolfSSL/wolfssl/archive/v3.15.7-stable.tar.gz ${WORKSPACE} RUN tar xzvf v3.15.7-stable.tar.gz WORKDIR ${WORKSPACE}/wolfssl-3.15.7-stable RUN ./autogen.sh RUN ./configure CFLAGS="-pipe -O2 -march=native -mtune=native -fomit-frame-pointer -fstack-check -fstack-protector-strong -mfpmath=sse -msse2avx -mavx2 -ftree-vectorize -funroll-loops -DTFM_TIMING_RESISTANT -DECC_TIMING_RESISTANT -DWC_RSA_BLINDING" --prefix=/usr/local --enable-tls13 --enable-openssh --enable-aesni --enable-intelasm --enable-keygen --enable-certgen --enable-certreq --enable-curve25519 --enable-ed25519 --enable-intelasm --enable-harden RUN make -j40 all RUN make install 

这是libcrypto ++安装的一部分

 ADD https://github.com/weidai11/cryptopp/archive/CRYPTOPP_8_2_0.tar.gz ${WORKSPACE} RUN rm -rf ${WORKSPACE}/cryptopp-CRYPTOPP_8_2_0 RUN tar xzvf ${WORKSPACE}/CRYPTOPP_8_2_0.tar.gz WORKDIR ${WORKSPACE}/cryptopp-CRYPTOPP_8_2_0 RUN make CFLAGS="-pipe -O2 -march=native -mtune=native -fPIC -fomit-frame-pointer -fstack-check -fstack-protector-strong -mfpmath=sse -msse2avx -mavx2 -ftree-vectorize -funroll-loops" CXXFLAGS="-pipe -O2 -march=native -mtune=native -fPIC -fomit-frame-pointer -fstack-check -fstack-protector-strong -mfpmath=sse -msse2avx -mavx2 -ftree-vectorize -funroll-loops" -j40 libcryptopp.a libcryptopp.so RUN make install 

和luajit

 ADD http://luajit.org/download/LuaJIT-2.0.5.tar.gz ${WORKSPACE} WORKDIR ${WORKSPACE} RUN tar xzvf LuaJIT-2.0.5.tar.gz WORKDIR ${WORKSPACE}/LuaJIT-2.0.5 RUN env CFLAGS="-pipe -Wall -pthread -O2 -fPIC -march=native -mtune=native -mfpmath=sse -msse2avx -mavx2 -ftree-vectorize -funroll-loops -fstack-check -fstack-protector-strong -fno-omit-frame-pointer" make -j40 all RUN make install 

LAppS的一个可选依赖项（可以忽略）是Microsoft mimalloc的新库。 该库可显着提高性能（约1％），但要求cmake-3.4或更高。 鉴于测试时间有限，我决定牺牲提到的性能改进。

在家用PC上，我不会在测试期间禁用mimalloc 。

让我们从存储库中签出LAppS：

 WORKDIR ${WORKSPACE} RUN rm -rf ITCLib ITCFramework lar utils LAppS RUN git clone https://github.com/ITpC/ITCLib.git RUN git clone https://github.com/ITpC/utils.git RUN git clone https://github.com/ITpC/ITCFramework.git RUN git clone https://github.com/ITpC/LAppS.git RUN git clone https://github.com/ITpC/lar.git WORKDIR ${WORKSPACE}/LAppS 

现在，我们需要从nbproject子目录中的所有Makefile中删除“ -lmimalloc”，以便我们可以构建LAppS（假设当前目录为$ {WORKSPACE} / LAppS）

 # find ./nbproject -type f -name "*.mk" -exec sed -i.bak -e 's/-lmimalloc//g' {} \; # find ./nbproject -type f -name "*.bak" -exec rm {} \; 

现在我们可以构建LAppS。 LAppS提供了几种构建配置，这些配置可能会也可能不会排除服务器端的某些功能：

• 具有SSL支持和统计信息收集支持
• 使用SSL且不收集统计信息（尽管在运行时用于动态LAppS调整的情况下，将继续进行最少的统计收集）
• 没有SSL，也没有统计信息收集。

在进行下一步之前，请确保您是/ opt / lapps目录的所有者（或使用sudo运行make installs）

让我们创建两种具有SSL支持和统计信息收集功能的二进制文件（不包含在$ {WORKSPACE} / LAppS目录中）：

 # make clean # make CONF=Release.AVX2 install # make CONF=Release.AVX2.NO_STATS.NO_TLS install 

生成的二进制文件是：

• dist / Release.AVX2 / GNU-Linux / lapps.avx2
• dist / Release.AVX2.NO_STATS.NO_TLS / GNU-Linux / lapps.avx2.nostats.notls

它们将被安装到/ opt / lapps / bin中。

请注意，用于Lua的WebSockets客户端模块始终带有SSL支持。 是否启用它取决于您在运行时用于连接的URI（ws：//或wss：//）。
