1、安装依赖

# 安装 etcd
wget https://github.com/etcd-io/etcd/releases/download/v3.4.13/etcd-v3.4.13-linux-amd64.tar.gz
tar -xvf etcd-v3.4.13-linux-amd64.tar.gz && \
    cd etcd-v3.4.13-linux-amd64 && \
    sudo cp -a etcd etcdctl /usr/bin/

# 添加 OpenResty 源
sudo yum install yum-utils
sudo yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo

# 安装 OpenResty 和 编译工具
sudo yum install -y openresty curl git gcc openresty-openssl111-devel unzip pcre pcre-devel

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

# 开启 etcd server
nohup etcd &

【etcd检查】

# 查看etcd安装版本
etcd --version
curl -L http://127.0.0.1:2380/version

# 查看端口
netstat -anp | grep 2380

# 安装目录
/usr/bin/

2、安装apisix

# 通过RPM包安装，这种安装方式适用于CentOS7操作系统
sudo yum install -y https://github.com/apache/apisix/releases/download/2.10.0/apisix-2.10.0-0.el7.x86_64.rpm

【初始化和启动 】

# 初始化依赖
apisix init

# 启动
apisix start

【若启动报错！】

[root@bpm-web apisix]# apisix start
/usr/local/openresty/luajit/bin/luajit /usr/local/apisix/apisix/cli/apisix.lua start

【原因：系统open files设置太少】 

 【解决】

vim /etc/security/limits.conf

【追加两行】 

* soft nofile 65536
* hard nofile 65536

【再次启动】

[root@bpm-web tyke]# apisix start
/usr/local/openresty/luajit/bin/luajit /usr/local/apisix/apisix/cli/apisix.lua start

【apisix检查】

# 查看帮助命令
