1.编译安装luajit:
wget https://github.com/openresty/luajit2/archive/refs/tags/v2.1-20220411.tar.gz
mv v2.1-20220411.tar.gz luajit2-v2.1-20220411.tar.gz
tar xvf luajit2-v2.1-20220411.tar.gz
cd luajit2-2.1-20220411/
[root@xianchaonode1 lua]# mkdir -p /usr/local/luajit2-2.1
make install PREFIX=/usr/local/luajit2-2.1
=>==== Successfully installed LuaJIT 2.1.0-beta3 to /usr/local/luajit2-2.1 ====
配置系统环境变量-编译安装nginx的时候使用:
vim /etc/profile
export LUAJIT_LIB=/usr/local/luajit2-2.1/lib
export LUAJIT_INC=/usr/local/luajit2-2.1/include/luajit-2.1
source /etc/profile
加载luajit2模块，nginx启动需要调用libluajit-5.1.so.2模块
vim /etc/ld.so.conf.d/libc.conf
/usr/local/lib
/usr/local/luajit2-2.1/lib/
ldconfig
2.编译安装lua核心库,nginx需要加载lua库:
2.1: lua-resty-core22
# wget https://github.com/openresty/lua-resty-core/archive/refs/tags/v0.1.23.tar.gz23
# mv v0.1.23.tar.gz lua-resty-core-v0.1.23.tar.gz
# tar zxvf lua-resty-core-v0.1.23.tar.gz
# cd lua-resty-core-0.1.23/
# make install PREFIX=/usr/local/luacore
2.2: lua-resty-lrucache
# wget https://github.com/openresty/lua-resty-lrucache/archive/refs/tags/v0.13.tar.gz
# mv v0.13.tar.gz lua-resty-rucache-v0.13.tar.gz
# tar xvf lua-resty-lrucache-v0.13.tar.gz
# cd lua-resty-lrucache-0.13/
# make install PREFIX=/usr/local/luacore
3.编译安装lua-cjson:
# wget https://github.com/mpx/lua-cjson/archive/refs/tags/2.1.0.tar.gz
# mv 2.1.0.tar.gz lua-cjson-2.1.0.tar.gz
# tar xvf lua-cjson-2.1.0.tar.gz
# cd lua-cjson-2.1.0/
# vim Makefile
21 LUA_INCLUDE_DIR = /usr/local/luajit2-2.1/include/luajit-2.1
# vim lua_cjson.c
1291 /*_-=-- INITIALISATION ===-= */
1292
1293 #if !defined(LUA_VERSION_NUM) || LUA_VERSION_NUM < 502
1294 /* Compatibility for Lua 5.1.
1295
1296* luaL_setfuncs() is used to create a module table where the functions have
1297* json_config_t as their first upvalue. Code borrowed from Lua 5.2 source. */
修改去掉static ：1298 void luaL_setfuncs (lua_State *l, const luaL_Reg *reg, int nup)
注,有警告无影响:
[root@xianchaonode1 lua-cjson-2.1.0]# make

mkdir -p //usr/local/lib/lua/5.1
cp cjson.so //usr/local/lib/lua/5.1
chmod 755 //usr/local/lib/lua/5.1/cjson.so
4.建备ngx_devel_kit源码:
# wget https://github.com/vision5/ngx_devel_kit/archive/refs/tags/v0.3.1.tar.gz
# mv v0.3.1.tar.gz ngx_devel_kit-v0.3.1.tar.gz
# tar xvf ngx_devel_kit-v0.3.1.tar.gz
5.准备Lua-nginx-module源码:
# wget https://github,com/openresty/lua-nginx-module/archive/refs/tags/v0.10.21.tar.gz
# mv v0.10.21.tar.gz lua-nginx-module-v0.10.21.tar.gz
[root@xianchaonode1 lua]# tar zxvf lua-nginx-module-v0.10.21.tar.gz
编译安装nginx:
# wget https://nginx.org/download/nginx-1.20.2.tar.gz
# tar xvf nginx-1.20.2.tar.gz
# cd nginx-1.20.2/
# ./configure --prefix=/apps/nginx \
--with-http_ssl_module \
--with-http_v2_module \
--with-http_realip_module \
--with-http_stub_status_module \
--with-http_gzip_static_module \
--with-pcre \
--with-stream \
--with-stream_ssl_module \
--with-stream_realip_module \
--add-module=../ngx_devel_kit-0.3.1/ \
--add-module=../lua-nginx-module-0.10.21/
# make && make install
