yum -y install lua-devel
cd LuaJIT-2.1.0-beta3
make && make install
添加环境变量
vim /etc/profile
export LUAJIT_LIB=/usr/local/lib
export LUAJIT_INC=/usr/local/include/luajit-2.1
source /etc/profile
cd ..
cd nginx-1.20.2
./configure --prefix=/opt/nginx --user=www --group=www --with-http_ssl_module --with-http_stub_status_module --with-stream --add-module=/root/soft/nginx/lua/ngx_devel_kit-0.3.0 --add-module=/root/soft/nginx/lua/lua-nginx-module-0.10.14
make && make install
如果是升级，只要执行到make就行
升级
cp /opt/nginx/sbin/nginx{,.old}
cd nginx-1.20.2/objs/
cp -rfp nginx /opt/nginx/sbin/nginx
systemctl restart nginxd （必要重启，不然不生效）
启动时候报错
[root@ip sbin]# ./nginx -V
./nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory
# vi /etc/ld.so.conf.d/lib.conf
/usr/local/lib
# ldconfig
现在安装lua-cjson
wget https://www.kyne.com.au/~mark/software/download/lua-cjson-2.1.0.tar.gz
tar -zxvf lua-cjson-2.1.0.tar.gz
cd lua-cjson-2.1.0
# 这里 make 检查报错，需要编辑 Makefile文件
vi Makefile
把 LUA_INCLUDE_DIR = $(PREFIX)/include/luajit-2.1 这里的路径改成我们上面安装设置的路劲
#这一步之后 make 还是报错：lua_cjson.c:1298:13: error: static declaration
当前路径下
#编辑lua_cjson.c文件，将1298行的 static void luaL_setfun 前面的 static去掉
#到此为止才make 成功
make && make install
