Mysql 8.0 源碼編譯 多實例安裝

https://blog.csdn.net/cuilouyi9469/article/details/100438142

1、準備工做

1. 下載安裝包

路徑：https://dev.mysql.com/downloads/mysql/

這裏選擇 mysq-8.0.16.tar.gz

2. 清理已有版本

##查詢

rpm -qa | grep mysql
rpm -qa | grep maria
##清理(若是存在的話)

yum remove mysql
##或者

yum remove mariadb

3. 安裝依賴包

(1)常規依賴

yum -y install gcc gcc-c++ ncurses ncurses-devel libaio-devel openssl openssl-devel

(2)特殊版本的依賴

編譯的時候，分別錯誤提示：

CMake 3.4.3 or higher is required.

                    GCC 5.3 or newer is required

因此須要安裝Cmake和GCC的相關版本

請參考： http://blog.itpub.net/69915315/viewspace-2648182

2、編譯安裝（軟件）

1. 解壓安裝包

tar -zxvf tar -zxvf mysql-8.0.16.tar.gz

2. cmake配置

   (1) 進入目錄 mysql-8.0.16 ,創建一個目錄，用於存放編譯好的軟件

   cd mysql-8.0.16
   mkdir xiaochong
   (2) 進入子目錄xiaochong，進行編譯前的配置。 主要cmake後是 . . , 執行其父目錄。

   cd xiaochong
   配置參數：

cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNODB_MEMCACHED=ON \
-DWITH_SSL=system \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DCOMPILATION_COMMENT="xiaochong edition" \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/usr/local/boost \
-DCMAKE_CXX_COMPILER=/usr/bin/g++ \
-DWITH_BOOST=/tmp

3. 編譯

make -j 10
4 . 安裝

make install
末尾以下提示，表示成功。

-- Configuring done

-- Generating done

-- Build files have been written to: /software/mysql-8.0.16/xiaochong

---

錯誤1 c++: error: unrecognized command line option ‘-std=c++14’

解決方式： 添加： -DCMAKE_CXX_COMPILER=/usr/bin/g++

3、建立數據庫

一、建立用戶

groupadd mysql
useradd -g mysql mysql

2. 建立相關目錄

mkdir -p /data/mysql/{3306,3307}/{data,log,tmp,innodb,innodb_log}
這裏是兩個實例的目錄，分別是3306和3307.

建立後，目錄結構以下：

[root@mysql80 /]# cd data

[mysql@mysql80 data]$ tree .

.

└── mysql

├── 3306

│ ├── data

│ ├── innodb

│ ├── innodb_log

│ ├── log

│ └── tmp

└── 3307

├── data

├── innodb

├── innodb_log

├── log

└── tmp

3. 修改目錄權限

chown -R mysql:mysql /data/mysql/
chown -R mysql:mysql /usr/local/mysql/

4. 添加環境變量

   echo 'export PATH=$PATH:/usr/local/mysql/bin' >> /etc/profile
   source /etc/profile

5. 添加配置文件

（1）3306

vim /data/mysql/3306/my3306.cnf
內容以下：

（1）3307

vim /data/mysql/3307/my3307.cnf
內容以下：

[client]

六、初始化數據庫

（1） 3306

mysqld --defaults-file=/data/mysql/3306/my3306.cnf --initialize --user=mysql
（2） 3307

mysqld --defaults-file=/data/mysql/3307/my3307.cnf --initialize --user=mysql
錯誤以下：

[mysql@mysql80 ~]$ mysqld --defaults-file=/data/mysql/3306/my.cnf --initialize --user=mysql

mysqld: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by mysqld)

mysqld: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by mysqld)

mysqld: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by mysqld)

mysqld: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by mysqld)

解析辦法：

緣由： 因爲咱們以前升級了gcc，也就是gcc-5.3.0. 但目錄 /lib64/ 下的庫文件連接的是 libstdc++.so.6 依然軟連接是低版本 libstdc++.so.6.0.19

[root@mysql80 /]# cd /lib64/

[root@mysql80 lib64]# ls -l | grep libstdc++.so.6

lrwxrwxrwx. 1 root root 19 Jun 19 14:36 libstdc++.so.6 -> libstdc++.so.6.0.19

-rwxr-xr-x. 1 root root 991616 Apr 24 22:24 libstdc++.so.6.0.19

進入到新安裝的gcc-5.3.0的目錄，進入lib64，查看 libstdc++.so.6，軟連接的是 libstdc++.so.6.0.21

[root@mysql80 gcc-5.3.0]# cd lib64/

[root@mysql80 lib64]# ls -l | grep libstdc++.so.6

lrwxrwxrwx. 1 root root 19 Jun 25 15:54 libstdc++.so -> libstdc++.so.6.0.21

lrwxrwxrwx. 1 root root 19 Jun 25 15:54 libstdc++.so.6 -> libstdc++.so.6.0.21

-rwxr-xr-x. 1 root root 11089328 Jun 25 15:54 libstdc++.so.6.0.21

處理： 刪除原來的軟連接，創建新的軟連接：

[root@mysql80 lib64]# rm -rf libstdc++.so.6

[root@mysql80 lib64]# ln -s /usr/local/gcc-5.3.0/lib64/libstdc++.so.6 libstdc++.so.6

[root@mysql80 lib64]# ls -l | grep libstdc++.so.6

lrwxrwxrwx. 1 root root 41 Jun 26 14:48 libstdc++.so.6 -> /usr/local/gcc-5.3.0/lib64/libstdc++.so.6

7.啓動服務

（1） 3306

/mysqld_safe --defaults-file=/data/mysql/3306/my.cnf --user=mysql &

（2）3307

/mysqld_safe --defaults-file=/data/mysql/3307/my.cnf --user=mysql &

8.登陸數據庫

這裏以3306實例爲例，3307步驟相同，只須要注意端口號便可，即大寫的 -P

（1）查找root@localhost的初始密碼，

查看當前錯誤日誌

more /data/mysql/3306/log/mysql-error.log

找到以下行，標紅的便是密碼：

[MY-010454] [Server] A temporary password is generated for root@localhost: ?/ihz.ew8SIy

mysql -uroot -p'?/ihz.ew8SIy' -P3306 -S /data/mysql/3306/mysql.sock

（2）登陸

mysql -uroot -p' ?/ihz.ew8SIy ' -P3306 -S /data/mysql/3306/mysql.sock

（3）修改密碼

ALTER USER 'root'@'localhost' IDENTIFIED WITH sha256_password BY 'Yxc@3306' PASSWORD EXPIRE INTERVAL 360 DAY;

（4） 查詢數據庫

ysql> show databases;

+--------------------+

| Database |

+--------------------+

| information_schema |

| mysql |

| performance_schema |

| sys |

+--------------------+

4 rows in set (0.00 sec)
