CentOS 7 上編譯安裝MySQL 5.6.23，centos5.6.23

CentOS 7 上編譯安裝MySQL 5.6.23，centos5.6.23

1.下載源碼

wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.23.tar.gz

2.解壓

tar zxvf mysql-5.6.23.tar.gz

3.安裝必要的包

sudo yum install cmake gcc-c++ ncurses-devel perl-Data-Dumper

4.進入mysql源碼目錄，產生makefile

cmake .

5.編譯

make

6.安裝

sudo make install

mysql將會安裝到/usr/local/mysql路徑。

7.添加mysql使用者和組

sudo groupadd mysqlsudo useradd -r -g mysql mysql

8.修改目錄和檔案許可權，安裝預設資料庫

cd /usr/local/mysqlsudo chown -R mysql .sudo chgrp -R mysql .sudo scripts/mysql_install_db --user=mysql

sudo chown -R root .

sudo chown -R mysql data

至此，mysql就可以啟動運行了。

9.啟動mysql

CentOS7內建MariaDB的支援，/etc下預設存在my.cnf檔案幹擾mysql運行，需要先刪掉

cd /etcsudo rm -fr my.cnf my.cnf.d

然後再/etc下重建my.cnf檔案，內容如下

# For advice on how to change settings please see# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html[mysqld]# Remove leading # and set to the amount of RAM for the most important data# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.# innodb_buffer_pool_size = 128M# Remove leading # to turn on a very important data integrity option: logging# changes to the binary log between backups.# log_bin# These are commonly set, remove the # and set as required.# basedir = .....# datadir = /data/mysql/data# port = .....# server_id = .....# socket = .....# Remove leading # to set options mainly useful for reporting servers.# The server defaults are faster for transactions and fast SELECTs.# Adjust sizes as needed, experiment to find the optimal values.# join_buffer_size = 128M# sort_buffer_size = 2M# read_rnd_buffer_size = 2M max_connection = 10000sql_mode = NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES #binary log log-bin = mysql-binbinlog_format = mixedexpire_logs_day = 30#slow query log slow_query_log = 1slow_query_log_file = /var/log/mysql/slow.loglong_query_time = 3log-queries-not-using-indexeslog-slow-admin-statements

現在可以啟動mysql了

sudo /usr/local/mysql/bin/mysqld_safe --user=mysql &

CentOS7 不能使用service控制mysql服務，而源碼安裝的mysql也沒有提供Systemd的控制指令碼。

於是編輯/etc/rc.d/rc.local檔案，添加mysql的開機啟動命令。

/usr/local/mysql/bin/mysqld_safe --user=mysql &

然後給/etc/rc.d/rc.local添加可執行許可權

sudo chmod a+x /etc/rc.d/rc.local

9.修改root密碼

/usr/loca/mysql/bin/mysql -urootuse mysql;UPDATE user SET password = PASSWORD('test2015') WHERE user = 'root';

GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'stcm2015';

FLUSH PRIVILEGES;

至此，安裝基本完成了，一個mysql就能用了。
