Error Summary
解决办法为执行下列语句删除冲突：
yum -y remove libstdc++-4.8.5-4.el7.i686
当 install-dependencies.sh 执行 linux-install-luarocks.sh 时报下列错误：
Configuring LuaRocks version 3.8.0...
Lua version detected: 5.1
Lua interpreter found: /usr/bin/lua
lua.h for Lua 5.1 not found (tried /usr/include/lua/5.1/lua.h /usr/include/lua5.1/lua.h /usr/include/lua-5.1/lua.h /usr/include/lua51/lua.h /usr/include/lua.h)
If the development files for Lua (headers and libraries)
are installed in your system, you may need to use the
--with-lua or --with-lua-include flags to specify their location.
If those files are not yet installed, you need to install
them using the appropriate method for your operating system.
Run ./configure --help for details on flags.
从 https://www.lua.org/download.html 下载 lua-5.4.6，解压后修改其中的 Makefile 文件，将 INSTALL_TOP 的值改为：
INSTALL_TOP= /usr/local/lua-5.4.6
执行：
make&&make install
成功后再执行：
ln -s /usr/local/lua-5.4.6 /usr/local/lua
更新 PATH，指向 lua-5.4.6：
export PATH=/usr/local/lua:$PATH
重新执行 install-dependencies.sh 完成安装。
在本文写作时，“APISIX_VERSION='3.6.1'” 并不可用，需改为“APISIX_VERSION='3.6.0'”。
执行“make deps”时报错：
[ info ] WARNING: OpenResty not found. You have to install OpenResty and add the binary file to PATH before install Apache APISIX.
下面这个错误同 openresty.repo 有关：
failure: repodata/repomd.xml from openresty: [Errno 256] No more mirrors to try.
https://openresty.org/package/centos/2.6/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
上面这个错误是因为 openresty.repo 配置的 baseurl 实际不存在：
# cat /etc/yum.repos.d/openresty.repo
[openresty]
name=Official OpenResty Open Source Repository for CentOS
baseurl=https://openresty.org/package/centos/$releasever/$basearch
skip_if_unavailable=False
gpgcheck=1
repo_gpgcheck=0
gpgkey=https://openresty.org/package/pubkey.gpg
enabled=1
enabled_metadata=1
在 CentOS 7.9 上查 basearch 和 releasever 的取值：
# python -c 'import yum, json; yb = yum.YumBase(); print json.dumps(yb.conf.yumvar, indent=2)'
Loaded plugins: fastestmirror
{
"arch": "ia32e",
"basearch": "x86_64",
"releasever": "2.6",
"uuid": "d20a9386-c8d2-225a-8e8d-916f99f582d1"
}
实际存在的，如：
https://openresty.org/package/centos/7/x86_64/repodata/repomd.xml
做下列改动就能通过：
# cat /etc/yum.repos.d/openresty.repo
[openresty]
name=Official OpenResty Open Source Repository for CentOS
#baseurl=https://openresty.org/package/centos/$releasever/$basearch
baseurl=https://openresty.org/package/centos/7/x86_64/
skip_if_unavailable=False
gpgcheck=1
repo_gpgcheck=0
gpgkey=https://openresty.org/package/pubkey.gpg
enabled=1
enabled_metadata=1
