前言

=====================================================================

c c++ 等等 需要这个编译器gcc，最近有DBA的朋友咨询RHEL7.6操作系统安装Mysql数据库时需要 高版本的GCC，研究了下发现坑不少，总结本文分享给大家

1.当前gcc版本

[root@rhel76 ~]# gcc -v

Using built-in specs.

COLLECT_GCC=gcc

COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/lto-wrapper

Target: x86_64-redhat-linux

Configured with: …/configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,objc,obj-c++,java,fortran,ada,go,lto --enable-plugin --enable-initfini-array --disable-libgcj --with-isl=/builddir/build/BUILD/gcc-4.8.5-20150702/obj-x86_64-redhat-linux/isl-install --with-cloog=/builddir/build/BUILD/gcc-4.8.5-20150702/obj-x86_64-redhat-linux/cloog-install --enable-gnu-indirect-function --with-tune=generic --with-arch_32=x86-64 --build=x86_64-redhat-linux

Thread model: posix

gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)

从以上可以看出当前版本为4.8.5，本次我们升级到10.1.0

2.安装gcc

[root@rhel76 ~]# tar -vxf gcc-10.1.0.tar.gz

[root@rhel76 gcc-10.1.0]# mkdir build

[root@rhel76 gcc-10.1.0]# cd build/

[root@rhel76 build]# …/configure --prefix=/usr/local/gcc-10.1.0/ --enable-checking=release --enable-languages=c,c++ --disable-multilib

configure: error: Building GCC requires GMP 4.2+, MPFR 3.1.0+ and MPC 0.8.0+.

Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify

their locations. Source code for these libraries can be found at

their respective hosting sites as well as at

https://gcc.gnu.org/pub/gcc/infrastructure/. See also

http://gcc.gnu.org/install/prerequisites.html for additional info. If

you obtained GMP, MPFR and/or MPC from a vendor distribution package,

make sure that you have installed both the libraries and the header

files. They may be located in separate packages.

从日志总可以看出有如下报错，故下面每个都安装

configure: error: Building GCC requires GMP 4.2+, MPFR 3.1.0+ and MPC 0.8.0+.

3.gmp安装

[root@jeames007 ~]# tar -vxf gmp-5.0.1.tar.bz2

[root@jeames007 ~]# cd gmp-5.0.1/

[root@jeames007 gmp-5.0.1]# make

[root@jeames007 gmp-5.0.1]# make install

make[4]: Leaving directory `/root/gmp-5.0.1’

make[3]: Leaving directory `/root/gmp-5.0.1’

make[2]: Leaving directory `/root/gmp-5.0.1’

make[1]: Leaving directory `/root/gmp-5.0.1’

4.MPFR编译

[root@jeames007 ~]# tar -vxf mpfr-3.1.5.tar.xz

[root@jeames007 ~]# cd mpfr-3.1.5/

[root@jeames007 ~]#./configure --prefix=/usr/local/mpfr-3.1.5 --with-gmp=/usr/local/gmp-5.0.1

[root@jeames007 mpfr-3.1.5]# make

[root@jeames007 mpfr-3.1.5]# make install

5.MPC编译

[root@jeames007 ~]# tar -vxf mpc-1.0.1.tar.gz

[root@jeames007 ~]# cd mpc-1.0.1

[root@jeames007 ~]# ./configure --prefix=/usr/local/mpc-1.0.1 --with-gmp=/usr/local/gmp-5.0.1 --with-mpfr=/usr/local/mpfr-3.1.5

[root@jeames007 mpc-1.0.1]# make

自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。

深知大多数Java工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则几千的学费，着实压力不小。自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《2024年Java开发全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。

既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上Java开发知识点，真正体系化！

由于文件比较大，这里只是将部分目录截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频，并且会持续更新！

如果你觉得这些内容对你有帮助，可以扫码获取！！（备注Java获取）

最后

既已说到spring cloud alibaba，那对于整个微服务架构，如果想要进一步地向上提升自己，到底应该掌握哪些核心技能呢？

就个人而言，对于整个微服务架构，像RPC、Dubbo、Spring Boot、Spring Cloud Alibaba、Docker、kubernetes、Spring Cloud Netflix、Service Mesh等这些都是最最核心的知识，架构师必经之路！下图，是自绘的微服务架构路线体系大纲，如果有还不知道自己该掌握些啥技术的朋友，可根据小编手绘的大纲进行一个参考。

如果觉得图片不够清晰，也可来找小编分享原件的xmind文档！

且除此份微服务体系大纲外，我也有整理与其每个专题核心知识点对应的最强学习笔记：
