Apache APISIX 快速入门之二 —— APISIX 单

作者: 独奏乱序 | 来源:发表于2021-06-22 12:13 被阅读0次

1、环境配置：

环境配置	版本
OS	CentOS Linux release 7.9.2009 (Core)
opentresty	1.19.3.2
OpenSSL	1.1.1k
Lua	5.1
LuaRocks	2.3.0
etcd	3.4.13
APISIX	2.6.0
APISIX Dashboard	2.7.0

2、克隆版本库

实际上，在官方的git版本库中已自带了许多自动化部署脚本，在 apisix/utils/中，可以使用其进行自动化部署。

# 使用码云（国内版本库）加速下载
cd /data/softwares && \
git clone git@gitee.com:iresty/apisix.git

3、安装依赖

1）安装 openresty

1. 安装依赖库

yum install -y curl git gcc glibc gcc-c++ openssl-devel pcre-devel yum-utils

2. 安装openresty以及openssl 依赖

yum-config-manager --add-repo https://openresty.org/package/fedora/openresty.repo && \
yum install -y openresty openresty-openssl111-devel

3. 软链至标准目录

使用yum安装，默认安装路径在/usr/local/openresty ，将其软链到标准目录 /data/applications，方便统一管理

ln -s /usr/local/openresty /data/applications

2）安装 ETCD

1. 下载二进制包

注意 2.6 版本的apisix只支持 3.4x 的 etcd

cd /data/softwares && \
wget -c https://github.com/etcd-io/etcd/releases/download/v3.4.13/etcd-v3.4.13-linux-amd64.tar.gz && \
tar xf etcd-v3.4.13-linux-amd64.tar.gz && \
cd etcd-v3.4.13-linux-amd64 && \
cp etcd* /usr/local/bin && \
mkdir -p /data/etcd/{conf,data,log}

2. 配置文件

编辑文件，路径: /data/etcd/conf/etcd.conf ，文件内容如下：

#[Member]
#ETCD_CORS=""
ETCD_DATA_DIR="/data/etcd/data"
#ETCD_WAL_DIR=""
ETCD_LISTEN_PEER_URLS="http://192.168.3.224:2380"

3.配置日志

文件路径: /etc/rsyslog.d/etcd.conf , 新增文件，编辑以下内容

if $programname == 'etcd' then /data/etcd/log/etcd.log
& stop

重启 rsyslog

systemctl restart rsyslog.service

4. 注册systemd

文件路径: /usr/lib/systemd/system/etcd.service, 新增文件，编译以下内容

[Unit]
Description=Etcd Server
After=network.target
After=network-online.target
Wants=network-online.target

[Service]
Type=notify
WorkingDirectory=/data/etcd
EnvironmentFile=/data/etcd/conf/etcd.conf

# set GOMAXPROCS to number of processors
ExecStart=/bin/bash -c "GOMAXPROCS=$(nproc) /usr/local/bin/etcd"

Restart=on-failure
LimitNOFILE=65536
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=etcd # without any quote

[Install]
WantedBy=multi-user.target

注意：ETCD3.4x 版本会自动读取环境变量的参数，所以EnvironmentFile文件中有的参数，不需要再次在ExecStart启动参数中添加，二选一，如同时配置，会触发以下类似报错是因。
image-20210616164807096.png

启动服务

systemctl daemon-reload && \
systemctl enable etcd.service && \
systemctl start etcd.service

3）安装 LuaRocks

apisix 自带了一键安装LuaRocks脚本linux-install-luarocks.sh，可以直接使用，但是需要配合yum安装或者apisix自带的自动安装 openresty 脚本linux-install-openresty.sh使用，其默认识别openresty安装路径为 /usr/local/openresty

1. 自动脚本安装

curl https://raw.githubusercontent.com/apache/apisix/master/utils/linux-install-luarocks.sh -sL | bash -

脚本内容：

#!/usr/bin/env bash

#

# you might need sudo to run this script
if [ -z ${OPENRESTY_PREFIX} ]; then
    OPENRESTY_PREFIX="/usr/local/openresty"
fi

wget https://github.com/luarocks/luarocks/archive/v3.4.0.tar.gz
tar -xf v3.4.0.tar.gz
cd luarocks-3.4.0 || exit

OR_BIN="$OPENRESTY_PREFIX/bin/openresty"
OR_VER=$($OR_BIN -v 2>&1 | awk -F '/' '{print $2}' | awk -F '.' '{print $1"."$2}')
if [[ -e $OR_BIN && "$OR_VER" == 1.19 ]]; then
    WITH_LUA_OPT="--with-lua=${OPENRESTY_PREFIX}/luajit"
else
    # For old version OpenResty, we still need to install LuaRocks with Lua
    WITH_LUA_OPT=
fi

./configure $WITH_LUA_OPT \
    > build.log 2>&1 || (cat build.log && exit 1)

make build > build.log 2>&1 || (cat build.log && exit 1)
sudo make install > build.log 2>&1 || (cat build.log && exit 1)
cd .. || exit
rm -rf luarocks-3.4.0

mkdir ~/.luarocks || true

# OpenResty 1.17.8 or higher version uses openssl111 as the openssl dirname.
OPENSSL_PREFIX=${OPENRESTY_PREFIX}/openssl
if [ -d ${OPENRESTY_PREFIX}/openssl111 ]; then
    OPENSSL_PREFIX=${OPENRESTY_PREFIX}/openssl111
fi

luarocks config variables.OPENSSL_LIBDIR ${OPENSSL_PREFIX}/lib
luarocks config variables.OPENSSL_INCDIR ${OPENSSL_PREFIX}/include

2.编译安装LuaRocks

由于也会存在已经安装有openresty的情况，比如我们已事先安装有 openresty 1.15.8.3 版本，下面介绍下使用自定义安装LuaRocks的方法。

1.19新版本的 openresty 已可以直接集成 luarocks，而之前的旧版本仍需要手动安装luarocks。

1⃣️ 下载解压 LuaRocks 源码包

cd /data/softwares/ && \
wget -c https://github.com/luarocks/luarocks/archive/v3.4.0.tar.gz && \
tar xf v3.4.0.tar.gz

2⃣️ 集成openresty的luajit

cd /data/softwares/luarocks-3.4.0 && \
./configure --prefix=/data/applications/openresty/luajit --with-lua=/data/applications/openresty/luajit --lua-suffix=jit --with-lua-include=/data/applications/openresty/luajit/include/luajit-2.1

3⃣️ 编译安装

make build && \
make install

4⃣️ 添加环境变量

vim /etc/profile.d/luarocks.sh
# 添加以下内容
export LUAROCK_HOME=/data/applications/openresty/luajit/bin
export PATH=${PATH}:${LUAROCK_HOME}

source /etc/profile.d/luarocks.sh

5⃣️ 验证安装

luarocks

image-20210615142621225.png

3. luarocks 加载 openssl（升级openssl）

1⃣️ 编译zlib 1.2.11

cd /data/softwares && \
wget -c http://www.zlib.net/fossils/zlib-1.2.11.tar.gz && \
tar xf zlib-1.2.11.tar.gz && \
cd zlib-1.2.11 && \
./configure --prefix=/usr/local/zlib && \
make && make install

2⃣️ 安装 OpenSSL 1.1.1

只用 openresty 官方提供的repo源可以直接安装

yum install yum-utils && \
yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo && \
yum install -y openresty-openssl111-devel && \
ln -s /usr/local/openresty/openssl111 /usr/local/openssl && \
make && make install

3⃣️ 修改openssl编译文件

vim /data/softwares/openresty-1.15.8.3/bundle/nginx-1.15.8/auto/lib/openssl/conf
# 将里面的所有“.openssl”删除，在删之前你可以看到其所在行表示的是一个路径，记得将“/”也删掉

4⃣️ 重新编译 openresty 并加载最新openssl

添加 --with-zlib=/data/softwares/zlib-1.2.8 --with-openssl=--with-openssl=/usr/local/openssl

mkdir -p /data/conf/nginx/bak && \ 
cp /data/applications/openresty/nginx/conf/nginx.conf /data/conf/nginx/bak && \
cd /data/softwares/openresty-1.15.8.3 && \
./configure -j2 --prefix=/data/applications/openresty --with-pcre-jit --with-ipv6 --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_sub_module --with-http_gzip_static_module --with-pcre --with-stream=dynamic --with-http_flv_module --add-module=/data/softwares/ngx_http_geoip2_module --add-module=/data/softwares/nginx_upstream_check_module --with-zlib=/data/softwares/zlib-1.2.11 --with-openssl=/usr/local/openssl && \
make -j2 && \
make install

image-20210615184153826.png

5⃣️ luarocks 加载 openssl

luarocks config variables.OPENSSL_LIBDIR /usr/local/openssl/lib && \
luarocks config variables.OPENSSL_LIBDIR /usr/local/openssl/include

4、部署apisix

1）安装

1. 下载rpm包

cd /data/softwares && \
wget -c https://github.com/apache/apisix/releases/download/2.6/apisix-2.6-0.x86_64.rpm

2. 安装apisix

yum localinstall -y apisix-2.6-0.x86_64.rpm

3. 软链至标准目录

使用yum安装，默认安装路径在/usr/local/apisix，将其软链到标准目录 /data/applications，方便统一管理

ln -s /usr/local/apisix /data/applications

2）配置

1. 配置etcd地址

文件地址: /data/applications/apisix/conf/config.yaml，修改etcd 配置

#

# contributor license agreements.  See the NOTICE file distributed with
# this work for additional information regarding copyright ownership.
# The ASF licenses this file to You under the Apache License, Version 2.0
# (the "License"); you may not use this file except in compliance with
# the License.  You may obtain a copy of the License at
#
#     http://www.apache.org/licenses/LICENSE-2.0
#

# distributed under the License is distributed on an "AS IS" BASIS,
# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
# See the License for the specific language governing permissions and
# limitations under the License.
#
# If you want to set the specified configuration value, you can set the new
# in this file. For example if you want to specify the etcd address:
#
etcd:
    host:
      - "http://192.168.3.224:2379"

# To configure via environment variables, you can use `${{VAR}}` syntax. For instance:
#
# etcd:
#     host:
#       - "http://${{ETCD_HOST}}:2379"
#
# And then run `export ETCD_HOST=$your_host` before `make init`.
#
# If the configured environment variable can't be found, an error will be thrown.
apisix:
  admin_key:
    - name: "admin"
      key: edd1c9f034335f136f87ad84b625c8f1  # using fixed API token has security risk, please update it when you deploy to production environment
      role: admin

2. 修改 apisix内置 nginx.conf（选项）

文件路径: /data/applications/apisix/conf/nginx.conf，目的在于开放外部访问限制，生产环境不推荐

sed -i '/deny/d' /data/applications/apisix/conf/nginx.conf && \
sed -i '/allow/d' /data/applications/apisix/conf/nginx.conf

3. 修改启动服务

文件路径: /data/applications/apisix/apisix/cli/ops.lua，取消 reload 方法中的init（初始化 nginx.conf）

local function reload(env)
    -- reinit nginx.conf
    -- init(env) 注释掉该行

    local test_cmd = env.openresty_args .. [[ -t -q ]]
    -- When success,
    -- On linux, os.execute returns 0,
    -- On macos, os.execute returns 3 values: true, exit, 0, and we need the first.
    local test_ret = execute((test_cmd))
    if (test_ret == 0 or test_ret == true) then
        local cmd = env.openresty_args .. [[ -s reload]]
        execute(cmd)
        return
    end

    print("test openresty failed")
end

3）启动

1. 修改systemd

文件路径: /usr/lib/systemd/system/apisix.service，增加 Restart 选项

[Unit]
Description=apisix
Conflicts=apisix.service
After=network-online.target

[Service]
Type=forking
WorkingDirectory=/usr/local/apisix
ExecStart=/usr/bin/apisix start
ExecStop=/usr/bin/apisix stop
ExecReload=/usr/bin/apisix reload
Restart=always

2. 启动服务

systemctl daemon-reload && \
systemctl enable apisix.service && \
systemctl start apisix.service

4）验证

1. get请求调用 restful_api

鉴权key位于文件/data/applications/apisix/conf/config.yaml中，apisix ==> admin_key

curl -s "http://127.0.0.1:9080/apisix/admin/services/" -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' | jq .

正常返回如下:

{
  "count":"1",
  "action":"get",
  "node":{
    "key":"/apisix/services",
    "nodes":{},
    "dir":true
  }
}

5、安装 apisix dashboard

1）安装

1. 下载rpm包

cd /data/softwares && \
wget -c https://github.com/apache/apisix-dashboard/releases/download/v2.7/apisix-dashboard-2.7-0.x86_64.rpm

2. 安装 dashboard

使用yum安装，默认安装路径在/usr/local/apisix/dashboard

yum localinstall -y apisix-dashboard-2.7-0.x86_64.rpm

2）配置

1. 修改 allow_list 和 etcd 配置

allow_list 添加 0.0.0.0/0 （白名单，按需添加）
etcd 修改 192.168.3.224:2379
