編譯安裝MySQL數據庫

MySQL官方網址
https://www.mysql.com/

在下載前，先作如下內容
檢測下系統內有沒有已經安裝過的舊版本的boost庫以及MySQL或者mariadb
rpm -qa boost mysql mariadb*
隨後將其卸載

yum remove boost* mysql* mariadb* -y

隨後建立對應文件夾，並下載對應軟件

mkdir /app/pack -p
mkdir /app/service -p

將軟件包下載到 /app/pack下

cd /app/pack #複製對應鏈接 wget下載
wget https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.27.tar.gz
wget https://cdn.mysql.com/archives/mysql-5.7/mysql-boost-5.7.27.tar.gz

開始編譯

建立MySQL的用戶
useradd -M -s /sbin/nologin mysql
tar xf mysql-boost-5.7.27.tar.gz
cd mysql-5.7.27
cmake -DCMAKE_INSTALL_PREFIX=/app/service/mysql \
-DMYSQL_DATADIR=/app/service/mysql/data/ \
-DSYSCONFDIR=/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DMYSQL_TCP_PORT=3306 \
-DMYSQL_UNIX_ADDR=/app/service/mysql/mysql.sock \
-DENABLED_LOCAL_INFILE=1 \
-DWITH_PARTITION_STORAGE_ENGINE=1 \
-DDEXTRA_CHARSET=utf8 \
-DEXTRA_CHARSETS=all \
-DDEFAULT_COLLATION=utf8_general_ci \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/root/mysql-5.7.27/boost/boost_1_59_0

echo $? #返回0則爲執行成功

make && make install 
echo $? 
ls /app/service/msql 會生成不少對應的目錄等

具體編譯參數 參考官網 https://dev.mysql.com/doc/refman/5.7/en/source-configuration-options.html
自定義配置文件

vi /etc/my.cnf
[mysqld]
basedir=/app/service/mysql
datadir=/app/service/mysql/data
port=3306
socket=/app/service/mysql/mysql.sock
character-set-server=utf8
log-error=/app/service/mysql/mysqld.log
pid-file=/app/service/mysql/mysqld.pid

配置簡單啓動命令，

cp /app/service/mysql/support-files/mysql.server /etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
修改文件內部份內容
vi /etc/init.d/mysqld
basedir=/app/service/mysql
datadir=/app/service/mysql/data

chown -R mysql.mysql /app/service/mysql
vi /etc/profile
export PATH=/app/service/mysql/bin:$PATH
source /etc/profile

初始化數據庫

mysqld --initialize --user=mysql --basedir=/app/service/mysql --datadir=/app/service/mysql/data/

啓動數據庫

/etc/init.d/mysqld start 
grep password /app/service/mysql/mysqld.log
 2020-07-05T09:00:18.508755Z 1 [Note] A temporary password is generated for root@localhost: LjqsH>r1p:We
 複製末尾的密碼
 mysql -uroot -pLjqsH>r1p:We 登錄數據庫

重置密碼

數據庫外
 mysqladmin -uroot -p password "123qwe"
Enter password:   #這個是讓你輸入原密碼。若沒有原密碼，則直接回車掠過
或者在數據庫內
alter user root@localhost identified by '123qwe';

自此數據庫安裝成功
