开源数据库MySQL DBA运维（2）编译安装

1，准备安装包

boost_1_59_0.tar.gz

https://nchc.dl.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz

cmake-2.8.12.2.tar.gz

https://cmake.org/files/v2.8/cmake-2.8.12.2.tar.gz

mysql-5.7.37.tar.gz

https://mirrors.ustc.edu.cn/mysql-ftp/Downloads/MySQL-5.7/mysql-5.7.37.tar.gz

中国科技大学开源：​​https://mirrors.ustc.edu.cn/mysql-ftp/Downloads/​​

2，准备目录

创建/home/tools目录，将所有的软件包放在一起

[root@localhost ~]#mkdir -p /home/tools/
[root@localhost ~]cd /home/tools/
[root@localhost tools]# ll
-rw-r--r--.  1 root root   83709983 Apr 19 22:07 boost_1_59_0.tar.gz
-rw-r--r--.  1 root root  732664114 May 11 21:33 mysql-5.7.37-el7-x86_64.tar.gz
-rw-r--r--.  1 root root   56248775 May 11 22:21 mysql-5.7.37.tar.gz

3，安装cmake安装包

[root@localhost tools]#tar xf cmake-2.8.12.2.tar.gz
[root@localhost tools]#cd cmake-2.8.12.2
[root@localhost cmake-2.8.12.2]#./configure
[root@localhost cmake-2.8.12.2]#gmake && gmake install

每一步结束后，可以使用​​ehco $?​​，当返回值为0时，说明编译过程正常

4，将boost库解压到/usr/local/目录

[root@localhost tools]#tar xf boost_1_59_0.tar.gz -C /usr/local/
[root@localhost tools]#cd /usr/local/
[root@localhost tools]#mv boost_1_59_0/ boost

5，安装依赖包

[root@localhost tools]#yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++

6，创建MySQL文件存放目录，用户和组

[root@localhost tools]#mkdir -p /application/mysql
[root@localhost tools]#mkdir -p /application/mysql/data/
[root@localhost tools]#mkdir -p /application/mysql/tmp/
[root@localhost tools]#mkdir -p /application/mysql/binlog/
[root@localhost tools]#mkdir -p /application/mysql/logs/

7，创建mysql组和用户

[root@localhost tools]#groupadd mysql
[root@localhost tools]#useradd mysql -s /sbin/nologin -M -g mysql
[root@localhost ]# chown -R mysql.mysql  /application/mysql
[root@localhost tools]#id mysql
uid=1001(mysql) gid=1001(mysql) groups=1001(mysql)

• -s /sbin/nologin 用户不能登录系统
• -M 不创建用户的HOME目录
• -g 指定用户登录组的GID或组名

8，编译安装MySQL 5.7

[root@localhost tools]#tar-xf mysql-5.7.37.tar.gz
[root@localhost tools]#cd mysql-5.7.27
[root@localhost mysql-5.7.37]#cmake . \
-DCMAKE_INSTALL_PREFIX=/application/mysql \
-DMYSQL_DATADIR=/application/mysql/data \
-DMYSQL_UNIX_ADDR=/application/mysql/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITHOUT_PARTITION_STORAGE_ENGINE=1 \
-DWITH_ZLIB=bundled \
-DWITH_EMBEDDED_SERVER=1 \
-DWITH_DEBUG=0 \
-DWITH_BOOST=/usr/local/boost

9，MySQL初始化

[root@localhost /]#./application/mysql/bin/mysql_install_db --user=mysql --datadir=/application/myaql/data
[root@localhost /]#/application/mysql/bin/mysqld --initialize --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data
[root@localhost /]#/application/mysql/bin/mysql_ssl_rsa_setup --datadir=/application/mysql/data

会生产临时密码在屏幕上，保存临时密码。

10，建立MySQL配置文件my.cnf

备份原有配置文件

[root@localhost /]#mv /etc/my.cnf  ~
[root@localhost /]#vim /etc/my.cnf

11，开机启动MySQL

[root@localhost /]#cp /application/mysql/support-files/mysql.server /etc/init.d/mysqld
[root@localhost /]# chkconfig --add mysqld
[root@localhost /]# chkconfig mysqld on
[root@localhost /]# service mysqld start
Starting MySQL. SUCCESS! 
[root@localhost /]# /application/mysql/bin/mysql -u root -p'ptiO_?,1QGza'

用第9步保存的密码

12，修改密码

[root@localhost /]# /application/mysql/bin/mysqladmin -u root -p'ptiO_?,1QGza' password '666666'

看到库即完成
