因为项目需求，需要在centos6.8 x64 系统上安装go 语言环境，一款好的IDE怎么能缺少呢？于是就选择了jetbrains goland. 安装的时候发现好多坑，记录一下，希望能帮到需要的朋友。
1. 升级glibc
centos 6.8 默认带的glibc 版本是2.12，而goland 需要2.14 和 2.15 版本。否则会出现错误
[test@localhost bin]$ ./goland.sh /home/test/GoLand-2020.2.2/jbr/bin/java: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /home/test/GoLand-2020.2.2/jbr/bin/../lib/jli/libjli.so)升级完2.14后再升级2.15.
这里以升级glibc 2.15为例，参考了
https://blog.csdn.net/officercat/article/details/39520227
http://www.blogdaren.com/post-2420.html?from=timeline
具体升级过程：
a. 下载源码包至/home/xxx 用户目录并解压
wget http://ftp.gnu.org/gnu/glibc/glibc-2.15.tar.gz
b. 切换至glibc-2.15
c. mkdir build
d. configure
[root@node1 ~]# ../glibc-2.15/configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin这里最好是安装到/usr 目录，网上有文章只带了--prefix 参数, 安装到/opt/glibc-2.15, 实验过了，可以是可以，需要去编辑软连接glibc.so.6, 安装完成后java 都起不来了。
e. make -j2
f. sudo make install
如果安装输出信息末尾出现
Your new glibc installation seems to be ok. make[1]: Leaving directory `/home/test/glibc-2.15'说明你安装成功了。
