CentOS6.5下安裝mysql

文檔參考: http://blog.csdn.net/u010257584/article/details/51315438mysql

Mysql5.7版本有較大的變化,特別是在mysql主從上面,能夠提供並行複製,因此效率上更高,之後若是有相似需求,須要提供主從複製的話,建議事業部同事選擇5.7的版本。c++

選擇安裝的包都爲源碼包,定義起來較爲方便,因爲所有都爲文字節目操做,因此截圖部分較少。sql

一. mysql 安裝數據庫

1. 基礎包安裝bootstrap

  a. 首先清理自帶的mysql相關的包socket

    i. yum -y remove mysql-*ide

  b. 安裝編譯mysql須要包ui

    i. yum install gcc gcc-c++ -y.net

    ii. yum install ncurses-devel –y線程

    iii. cmake 安裝,版本要求2.8或者3.0以上的

 

    tar xvf cmake*

    cd cmake-3.4.3

    ./configure

    make –j 10     ---------------數字爲表cpu核數,並行執行,加快編譯速度

    make install

注意:boost也爲mysql編譯必須的包,5.7對其版本也有要求,下載mysql包含boost的就無需手動在安裝了---------下面步驟可略過

  tar xvf boost*

  cd boost_1_61_0

  ./bootstrap.sh –prefix=/usr/local/

  ./b2

  ./b2 install

2. mysql環境準備

  a. mkdir -pv /data/mysql

  b. useradd -s /sbin/nologin mysql

  c. chown -R mysql.mysql /data/mysql

3. 編譯安裝mysql

  a. tar xvf mysql-boost-5.7.12.tar.gz

  b. cd mysql-5.7.12

  c. cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql  -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=/opt/package/boost_1_59_0/        ----------制定mysql安裝目錄、默認字符集、boost路徑

  d. make -j 40 && make install

4. mysql初始化

  a. 創建mysql配置文件  /etc/my.cnf   -----不管需不須要配置主從,都建議先把server-id以及log-bin配置了,避免之後有添加配置主從的要求

   拷貝配置文件模板爲新的mysql配置文件

   cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf

     # cat /etc/my.cnf

   [client]

   port = 3306

   socket = /tmp/mysql.sock

    default-character-set = utf8mb4

   [mysqld]

   port = 3306

   socket = /tmp/mysql.sock

   basedir = /usr/local/mysql

   datadir = /data/mysql

   pid-file = /data/mysql/mysql.pid

   user = mysql

   server-id = 29

   init-connect = 'SET NAMES utf8mb4'

   character-set-server = utf8mb4

   max_heap_table_size = 8M

   tmp_table_size = 16M

   read_buffer_size = 2M

  b. /usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql         -------注意5.7以前的版本用mysql_install_db初始化

    例如:./scripts/mysql_install_db --datadir=/data/mysql5.6/ --user=mysql --basedir=/usr/local/mysql5.6/ --defaults-file=/etc/my.cnf.5.6

    啓動: /usr/local/mysql5.6/bin/mysqld_safe --defaults-file=/etc/my56.cnf &

    關閉:mysqladmin –u root  -h 127.0.0.1 –port 3307 shutdown

         mysqladmin -uroot -p1234#Byd  -S /tmp/mysql5.6.sock shutdown

    安裝多個實例,舊版本初始化時候要指定—defaults-file

    而後初始化密碼時候也要指定對應的端口或者socket,例如:

    /usr/local/mysql5.6/bin/mysqladmin -u root -h 127.0.0.1 --port 3307 password 'password'

    /usr/local/mysql5.6/bin/mysqladmin -u root --socket --port 3307 password 'password'

   c. 啓動mysql, /usr/local/mysql/bin/mysqld_safe &

  d. 設置mysql root登錄密碼:/usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'127.0.0.1' identified by \"1234#Byd\" with grant option;"

                /usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'localhost' identified by \"1234#Byd\" with grant option;"

  e. 其餘,配置mysql服務以及mysql bin環境變量

    cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql

    chmod 755 !$

    能夠經過 service mysql start/status/stop 管理

    ln  -s  /usr/local/mysql/bin/* /usr/local/bin/

 

登錄Mysql:mysql -u root -p1234#Byd

 

二. 主從配置

1. 安裝上面的操做配置主從,先把mysql先配置了(下面主從僅適用於新安裝的,已有的數據庫,要求有配置server-id,以及開啓二進制日誌的前提下才能夠配置主從,須要先把主庫導出,而後配置同步)

2. 主從差別,配置文件server-id不一樣便可

3. 在主庫上建立用於複製的用戶

grant replication slave on *.* to slave@'10.9.31.%' identified by 'slave#2016?';

4. 主庫查詢狀態:查詢當前日誌文件及position,用於日誌恢復

五、從庫配置到主庫的複製

change master to master_host='10.9.31.27',master_user='slave',master_password='slave#2016?',master_log_file='mysql-bin.000004',master_log_pos=1225;

開啓複製:start slave;

查看複製狀態:show slave status\G; 查詢到複製的IO和SQL線程都爲YES表示配置成功。

 

6. 驗證

在主庫建立庫或者表,在從庫查詢。

 

注意:5.6以上版本開啓了GTID特性,mysql本身識別複製log及pos,方便管理;因爲上面my.cnf已經開啓了gtid,可使用該特性完成複製

 

1:配置帳號

grant replication slave,replication client on *.* to repl@'10.9.31.29' identified by 'Repl#2016';

change master to master_host='10.9.31.26',master_port=3306,master_user='repl',master_password='Repl#2016',master_auto_position=1;

 

啓動複製

 

start slave;

show slave status\G;

show processeslist;
