开发笔记:tengine2.3.2负载均衡和haproxy七层代理

下载tengine-2.3.2
[root@ha1 soft]# wget http://tengine.taobao.org/download/tengine-2.3.2.tar.gz
添加www用户
[root@ha1 soft]# useradd www -s /sbin/nologin -u 1000
[root@ha1 soft]# ll
-rw-r--r-- 1 root root 2835884 Sep 5 2019 tengine-2.3.2.tar.gz

编译安装tengine
[root@ha1 soft]# yum -y install gcc gcc-c++
[root@ha1 soft]# tar -zxvf tengine-2.3.2.tar.gz
[root@ha1 soft]# cd tengine-2.3.2/
[root@localhost tengine-2.3.2]# ./configure
--prefix=/data/tools/tengine-2.3.2

--with-http_v2_module
--with-http_realip_module
--with-http_stub_status_module
--with-http_gzip_static_module

[root@ha1 tengine-2.3.2]# make -j 2 && make install
[root@ha1 conf]# pwd
/data/tools/tengine/conf

配置tengine
[root@ha1 conf]# grep -E "vhost|www" nginx.conf
user www www;
include vhost/*.conf;
配置虚拟主机
[root@ha1 conf]# mkdir vhost
[root@ha1 conf]#cd vhost
[root@ha1 vhost]# cat localhost.conf
server {
listen 9001;
server_name localhost;
index index.html index.htm index.php;
root /data/wwwroot/localhost;
}
配置代理
[root@ha1 vhost]# cat api.abc.com.conf
upstream api {
server 127.0.0.1:9001;
}

server {
listen 80;
server_name api.abc.com;

location / {
proxy_pass http://api;
}
}
windows添加本地host解析
C:WindowsSystem32driversetchosts
192.168.100.116 api.abc.com

测试
访问9001端口

访问代理地址

配置haproxy七层代理，实现/a转发到a集群地址，/b转发到b集群地址。
编译安装haproxy
tar xvfhaproxy-1.8.20.tar.gz && cd haproxy-1.8.20

#ARCH:平台架构,TARGET：内核版本,USE_PCRE:开启pcre，USE_OPENSSL：开启ssl
#USE_SYSTEMD:支持使用 -Ws参数（systemd-aware master-worker 模式）启动Haproxy，从而实现单主进程多子进程运行模式
#USE_CPU_AFFINITY:开启haproxy进程与CPU核心绑定
make ARCH=x86_64 TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_SYSTEMD=1 USE_CPU_AFFINITY=1 PREFIX=/data/tools/haproxy-1.8.20

make install PREFIX=/data/tools/haproxy-1.8.20
cp haproxy /usr/sbin/
cd /data/tools/ && ln -sv /data/tools/haproxy-1.8.20 haproxy
mkdir -p /etc/haproxy/
useradd haproxy -s /sbin/nologin
mkdir /var/run/haproxy
chown -R haproxy.haproxy /var/run/haproxy
