MySQL-8.0.12源碼安裝執行個體

1、通過官網下載下傳對應的版本後，通過FTP上傳至雲伺服器的/usr/local/src 目錄

2、解壓縮檔案

[root@JSH-01 src]# ls
mysql-boost-8.0.12.tar.gz
[root@JSH-01 src]# tar zxvf mysql-boost-8.0.12.tar.gz
[root@JSH-01 src]# ls
mysql-8.0.12  mysql-boost-8.0.12.tar.gz           

3、重命名檔案夾

[root@JSH-01 src]# mv mysql-8.0.12  mysql
[root@JSH-01 src]# ls
mysql  mysql-boost-8.0.12.tar.gz
[root@JSH-01 src]# cd mysql
[root@JSH-01 mysql]# ls
boost           config.h.cmake    Doxyfile.in        libbinlogevents      man         plugin             sql            testclients  win
client          configure.cmake   doxygen_resources  libbinlogstandalone  mysql-test  README             sql-common     unittest
cmake           dbug              extra              libmysql             mysys       run_doxygen.cmake  storage        utilities
CMakeLists.txt  Docs              include            libservices          mysys_ssl   scripts            strings        VERSION
components      Doxyfile-ignored  INSTALL            LICENSE              packaging   share              support-files  vio           

4、安裝cmake工具 yum install -y cmake

5、cmake建構編譯環境

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/src/mysql  -DMYSQL_DATADIR=/usr/local/src/mysql/var  -DSYSCONFDIR=/usr/local/src/mysql/etc -DWITH_DEBUG=0  -DWITH_INNODB_MEMCACHED=1  -DWITH_PARTITION_STORAGE_ENGINE=1  -DENABLED_PROFILING=0  -DCMAKE_C_FLAGS="-O3"  -DCMAKE_CXX_FLAGS="-O3"
           

6、cmake報錯彙總：

錯誤1、 CMake Warning at CMakeLists.txt:185 (MESSAGE):
  Could not find devtoolset gcc           

解決方案：yum install -y gcc

再次執行cmake編譯

錯誤2、**-- Could NOT find Git (missing:  GIT_EXECUTABLE) **           

解決方案：yum install -y git

錯誤3、-- The CXX compiler identification is unknown
CMake Error: your CXX compiler: "CMAKE_CXX_COMPILER-NOTFOUND" was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or name.           

解決方案：yum install -y gcc gcc-c++

錯誤4、CMake Error at cmake/boost.cmake:101 (MESSAGE):
  You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>           

解決方案：編譯選項中增加

-DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/src/mysql

回車後，系統會自動下載下傳并解壓縮該檔案

錯誤5、Cannot find appropriate system libraries for WITH_SSL=system.
Make sure you have specified a supported SSL version. 
Valid options are : 
system (use the OS openssl library), 
yes (synonym for system), 
</path/to/custom/openssl/installation>, 
wolfssl (use wolfSSL. See extra/README-wolfssl.txt on how to set this up)

錯誤6、CMake Error at cmake/ssl.cmake:68 (MESSAGE):
  Please install the appropriate openssl developer package.
           

解決方案5：編譯選項中增加 -DWITH_SSL=system

解決方案6：yum install ncurses-devel 和 yum install openssl-devel

7、執行編譯 make -j N(N為線程數，一般為伺服器中CPU的個數)

檢視Linux系統CPU資訊：

cat /proc/cpuinfo           

檢視Linux系統CPU實體個數：

cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l           

8、cmake -j 編譯過程中的錯誤資訊

[ 56%] Building CXX object storage/innobase/CMakeFiles/innobase.dir/handler/i_s.cc.o
錯誤  c++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
make[2]: *** [storage/innobase/CMakeFiles/innobase.dir/handler/handler0alter.cc.o] Error 4
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [storage/innobase/CMakeFiles/innobase.dir/all] Error 2
make: *** [all] Error 2
           

解決方案：根據錯誤資訊提示 internal compiler error: Killed (program cc1plus) 判斷為編譯過程中記憶體耗盡, 導緻了編譯中斷，解決辦法就是增加一個交換分區:

[root@JSH-01 mysql]# dd if=/dev/zero of=/swapfile bs=1k count=2048000    //建立分區檔案, 大小 2G
2048000+0 records in
2048000+0 records out
2097152000 bytes (2.1 GB) copied, 16.9483 s, 124 MB/s
[root@JSH-01 mysql]# mkswap /swapfile   //生成 swap 檔案系統
