EOS编译（环境Centos7.4）

首先从github上拉eos的源码

git clone https://github.com/eosio/eos --recursive

如果没加--recursive，则拉完源码后需要在源码目录执行以下命令（如果没有执行，执行编译命令时会提示）

git submodule update --init --recursive

执行编译命令

sh eosio_build.sh

编译完成后

[100%] Built target nodeos

        EOSIO has been successfully built. 02:17:15

        To verify your installation run the following commands:

        /root/opt/mongodb/bin/mongod -f /root/opt/mongodb/mongod.conf &
        source /opt/rh/python33/enable
        export PATH=${HOME}/opt/mongodb/bin:$PATH
        cd /opt/eos/build; make test

如果顺利，则编译完成。在我的实践中，估计是因为网络的原因（墙），需要做一些操作。

1） 下载mongodb的时候，需要将下载地址替换掉，在文件script/eosio_build_centos.sh

#STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz)
STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 http://downloads.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz)

2)手动下载mongo-c-driver-1.9.3.tar.gz，放到指定目录，然后在脚本中注释掉下载命令，改为拷贝命令

#		STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 \
#		"https://github.com/mongodb/mongo-c-driver/releases/download/1.9.3/mongo-c-driver-1.9.3.tar.gz" )
#		if [ "${STATUS}" -ne 200 ]; then
#			rm -f "${TEMP_DIR}/mongo-c-driver-1.9.3.tar.gz"
#			printf "\\tUnable to download MongoDB C driver at this time.\\n"
#			printf "\\tExiting now.\\n\\n"
#			exit 1;
#		fi
		cp /opt/eos/scripts/mongo-c-driver-1.9.3.tar.gz ${TEMP_DIR}/

3）之前安装了tcmaloc，但是没有配置链接

[root@localhost eos]# build/programs/nodeos/nodeos 
build/programs/nodeos/nodeos: error while loading shared libraries: libtcmalloc.so.4: cannot open shared object file: No such file or directory

解决方案：

[root@localhost gperftools-master]# echo /usr/local/lib > /etc/ld.so.conf.d/libtcmalloc.conf
[root@localhost gperftools-master]# ldconfig
