系统为centos 8.1

Tengine 2.3.2 编译安装

# 注意必需使用openresty提供的luajit

# yum remove luajit

git clone https://github.com/openresty/luajit2.git

cd luajit2/

make

make install

# 默认安装到/usr/local/lib/ /usr/local/include/luajit-2.1

echo '/usr/local/lib/' > /etc/ld.so.conf.d/luajit.conf

ldconfig

git clone git://github.com/vozlt/nginx-module-vts.git

# 该模块提供非常详细的指标数据，有网页，并支持promethues

# ngx_http_lua_module部分功能依赖ngx_devel_kit

# 若不安装该模块 set_by_lua* 指令将不可用

wget https://github.com/vision5/ngx_devel_kit/archive/v0.3.1.tar.gz

tar zxf v0.3.1.tar.gz

wget http://tengine.taobao.org/download/tengine-2.3.2.tar.gz

tar zxf tengine-2.3.2.tar.gz

cd tengine-2.3.2/

yum install pcre-devel openssl-devel GeoIP-devel

# yum 安装的luajit是2.1的需要使用上面编译安装的
