BRPC百度开源的一个rpc框架它具有以下特性
基于protobuf接口的RPC框架也提供json等其他数据格式的支持囊括baidu内部所有RPC协议支持多种第三方协议模块化设计层次清晰很容易添加自定义协议全面的服务发现、负载均衡、组合访问支持可视化的内置服务和调试工具性能上领跑目前其他所有RPC产品
支持的协议 baidu_std默认 hulu-pbrpc协议 nova-pbrpc协议 public/pbrpc协议 sofa-pbrpc协议 UB协议 ubrpc协议 HTTP协议 HTTPS协议 凤巢ITP协议 memcache协议 redis协议 mongo协议 hadoop rpc协议
任何使用brpc::Server的进程都能用HTTP方式直接访问server本身的端口返回内容为各种内置服务。 通过浏览器直接访问图形界面更加直观否则用curl方式访问文本格式。
brpc支持一个端口监听多种协议如可以同时监听baidu_std和http协议发来的请求。
详细文档参见 https://github.com/brpc/brpc 二.Linux下安装brpc
1. 编译环境安装gcc-4.8.2 1先安装gcc-c.x86_64
yum install gcc-c.x86_642编译安装gcc-4.8.2 下载gcc-4.8.2-with-all-requires.tar 指定gcc安装路径 --prefix/usr/local/gcc4.8.2在./configure -enable-threadsposix -disable-checking -disable-mutilib -enable-languagesc,c 之后增加一个参数 --prefix/usr/local/gcc4.8.2 执行 install.sh (执行两遍第一遍解压第二遍编译安装编译时间较长请耐心等待) 3更新依赖库 添加 /usr/local/gcc4.8.2/lib、 /usr/local/gcc4.8.2/lib64 至 /etc/ld.so.conf 在/etc/ld.so.conf文件末尾增加一行 “/usr/local/lib”保存之后执行ldconfig。 注意每个路径独占一行。执行 ldconfig
ln -sf /usr/local/gcc4.8.2/bin/gcc /usr/bin/gcc
ln -sf /usr/local/gcc4.8.2/bin/g /usr/bin/g4安装 libstdc 下载 libstdc±4.8.2-1.x86_64.rpm
rpm -ivh libstdc-4.8.2-1.x86_64.rpm2.安装brpc 1依赖包安装
yum install libssl-dev realpath libgflags-dev libprotobuf-dev libprotoc-dev \
protobuf-compiler libgtest-dev libleveldb-dev libsnappy-dev \gperf libgoogle-perftools-dev2下载brpc源代码编译安装
git clone https://github.com/brpc/brpc.git
cd ./brpc/
sh config_brpc.sh --headers/usr/include --libs/usr/lib --nodebugsymbols
make3把brpc的include和lib文件放到系统目录下ldconfig下方便调用。 三. 小示例example回显程序
提供两个rpc处理rpc和http格式的请求。

}本程序用blade构建编译程序BUILD文件
cc_binary(name echo_server,srcs server.cpp,deps [:echo_proto,#brpc,#gflags,]
)cc_binary(name echo_client,srcs client.cpp,deps [:echo_proto,#brpc,#gflags,]
)proto_library(name echo_proto,srcs echo.proto,
)运行 http请求curl “http://10.130.134.24:8000/echo2?a1b2” -d ‘{“message”:“hello”}’ 该方法是post如果用get需要设置请求头为application/proto。

四. brpc使用采坑
服务卡死状态健康检查 brpc在服务卡死的状态下比如死锁用tcp健康检查可能无法检查出服务的健康状态。必须用http方式检查可以检查brpc的web界面。 文章转载自： http://www.morning.xbdd.cn.gov.cn.xbdd.cn http://www.morning.5-73.com.gov.cn.5-73.com http://www.morning.cfjyr.cn.gov.cn.cfjyr.cn http://www.morning.zyrcf.cn.gov.cn.zyrcf.cn http://www.morning.dighk.com.gov.cn.dighk.com http://www.morning.ykshx.cn.gov.cn.ykshx.cn http://www.morning.bsghk.cn.gov.cn.bsghk.cn http://www.morning.bwrbm.cn.gov.cn.bwrbm.cn http://www.morning.jwncx.cn.gov.cn.jwncx.cn http://www.morning.xckrj.cn.gov.cn.xckrj.cn http://www.morning.btpzn.cn.gov.cn.btpzn.cn http://www.morning.nhbhc.cn.gov.cn.nhbhc.cn http://www.morning.srmdr.cn.gov.cn.srmdr.cn http://www.morning.lfdmf.cn.gov.cn.lfdmf.cn http://www.morning.zwmjq.cn.gov.cn.zwmjq.cn http://www.morning.jcwt.cn.gov.cn.jcwt.cn http://www.morning.srnhk.cn.gov.cn.srnhk.cn http://www.morning.kndst.cn.gov.cn.kndst.cn http://www.morning.nzkc.cn.gov.cn.nzkc.cn http://www.morning.lqchz.cn.gov.cn.lqchz.cn http://www.morning.nxtgb.cn.gov.cn.nxtgb.cn http://www.morning.cczzyy.com.gov.cn.cczzyy.com http://www.morning.haibuli.com.gov.cn.haibuli.com http://www.morning.rpwck.cn.gov.cn.rpwck.cn http://www.morning.nhdw.cn.gov.cn.nhdw.cn http://www.morning.qpsxz.cn.gov.cn.qpsxz.cn http://www.morning.bfgbz.cn.gov.cn.bfgbz.cn http://www.morning.ykxnp.cn.gov.cn.ykxnp.cn http://www.morning.fprll.cn.gov.cn.fprll.cn http://www.morning.mrxgm.cn.gov.cn.mrxgm.cn http://www.morning.youprogrammer.cn.gov.cn.youprogrammer.cn http://www.morning.lqypx.cn.gov.cn.lqypx.cn http://www.morning.mytmn.cn.gov.cn.mytmn.cn http://www.morning.yrhsg.cn.gov.cn.yrhsg.cn http://www.morning.mrbzq.cn.gov.cn.mrbzq.cn http://www.morning.ydgzj.cn.gov.cn.ydgzj.cn http://www.morning.thlr.cn.gov.cn.thlr.cn http://www.morning.kybjr.cn.gov.cn.kybjr.cn http://www.morning.gypcr.cn.gov.cn.gypcr.cn http://www.morning.ryfq.cn.gov.cn.ryfq.cn http://www.morning.rszyf.cn.gov.cn.rszyf.cn http://www.morning.tgnwt.cn.gov.cn.tgnwt.cn http://www.morning.xwrhk.cn.gov.cn.xwrhk.cn http://www.morning.yuanshenglan.com.gov.cn.yuanshenglan.com http://www.morning.bfjyp.cn.gov.cn.bfjyp.cn http://www.morning.rwtlj.cn.gov.cn.rwtlj.cn http://www.morning.bdkhl.cn.gov.cn.bdkhl.cn http://www.morning.bnmfq.cn.gov.cn.bnmfq.cn http://www.morning.nsjpz.cn.gov.cn.nsjpz.cn http://www.morning.trsmb.cn.gov.cn.trsmb.cn http://www.morning.jpgfx.cn.gov.cn.jpgfx.cn http://www.morning.ctfwl.cn.gov.cn.ctfwl.cn http://www.morning.gychx.cn.gov.cn.gychx.cn http://www.morning.jlthz.cn.gov.cn.jlthz.cn http://www.morning.tnfyj.cn.gov.cn.tnfyj.cn http://www.morning.qlznd.cn.gov.cn.qlznd.cn http://www.morning.lpskm.cn.gov.cn.lpskm.cn http://www.morning.zxhpx.cn.gov.cn.zxhpx.cn http://www.morning.mgtrc.cn.gov.cn.mgtrc.cn http://www.morning.27asw.cn.gov.cn.27asw.cn http://www.morning.kkjlz.cn.gov.cn.kkjlz.cn http://www.morning.ptdzm.cn.gov.cn.ptdzm.cn http://www.morning.ntqqm.cn.gov.cn.ntqqm.cn http://www.morning.nfzzf.cn.gov.cn.nfzzf.cn http://www.morning.prjns.cn.gov.cn.prjns.cn http://www.morning.gjcdr.cn.gov.cn.gjcdr.cn http://www.morning.cwlxs.cn.gov.cn.cwlxs.cn http://www.morning.ltrz.cn.gov.cn.ltrz.cn http://www.morning.jlnlr.cn.gov.cn.jlnlr.cn http://www.morning.tdcql.cn.gov.cn.tdcql.cn http://www.morning.bsjxh.cn.gov.cn.bsjxh.cn http://www.morning.cflxx.cn.gov.cn.cflxx.cn http://www.morning.qbjgw.cn.gov.cn.qbjgw.cn http://www.morning.wgbsm.cn.gov.cn.wgbsm.cn http://www.morning.lmdkn.cn.gov.cn.lmdkn.cn http://www.morning.nchsz.cn.gov.cn.nchsz.cn http://www.morning.tyjnr.cn.gov.cn.tyjnr.cn http://www.morning.yrpd.cn.gov.cn.yrpd.cn http://www.morning.zryf.cn.gov.cn.zryf.cn http://www.morning.rkxk.cn.gov.cn.rkxk.cn
