一、准备工作
1.1)源码包
mysql-5.6.26.tar.gz
1.2）解决依赖
[00:37:56 root@tuxing ~]#yum install -y cmake ncurses-devel
二、源码安装MySql
1.1）解压到指定目录(/usr/local/src)
解压后进入到目录里
[11:42:54 root@tuxing software]#tar xf mysql-5.6.26.tar.gz -C
/usr/local/src/ ; cd /usr/local/src/mysql-5.6.26
[11:42:59 root@tuxing mysql-5.6.26]#
1.2）创建mysql用户
11:42:59 root@tuxing mysql-5.6.26]#useradd -M -s /sbin/nologin mysql
1.3）编译mysql
[11:46:53 root@tuxing mysql-5.6.26]# cmake \
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS=all \
-DWITH_MYISAM_STORAGE_ENGINE=1 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_MEMORY_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/usr/local/mysql/data \
-DMYSQL-USER=mysql
若报错了，执行两步重新编译
yum install -y git gcc gcc-c++
rm CMakeCache.txt
后面就直接执行

[11:46:53 root@tuxing mysql-5.6.26]#make -j 2 ; make install
//make过程有点长，我们耐心等待！
1.4）配置mysql
[11:58:18 root@tuxing ~]#chown -R mysql:mysql /usr/local/mysql/ #属主属组更改
[11:59:10 root@tuxing ~]# cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y
[11:59:13 root@tuxing ~]# #覆盖原配置文件
[11:59:13 root@tuxing ~]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
#启动脚本
[12:01:42 root@tuxing ~]#vi /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data #找到并添加
[12:03:29 root@tuxing ~]#chkconfig mysqld on #开机启动
三、初始化数据库
[12:05:12 root@tuxing ~]#/usr/local/mysql/scripts/mysql_install_db \
--defaults-file=/etc/my.cnf \
--basedir=/usr/local/mysql/ \
--datadir=/usr/local/mysql/data/ \
--user=mysql
------------------------------检查一下若出现两个OK则表示成功
[12:05:12 root@tuxing ~]#ls /usr/local/mysql/data/ #检查有无mysql和test
[12:07:15 root@tuxing ~]#vim /etc/profile.d/mysql.sh #添加环境变量
后续操作：
[12:10:11 root@tuxing ~]#source /etc/profile.d/mysql.sh #source一下脚本
[12:11:42 root@tuxing ~]# service mysqld start #启动数据库成功
Starting MySQL. SUCCESS!
[12:11:58 root@tuxing ~]#systemctl start mysqld #centos7.5中启动数据库
[12:12:28 root@tuxing
~]#mysql_secure_installation #初始安全设置（设置root密码，123456）密码可以根据自己设置，其他直接回车 [12:13:34 root@tuxing ~]#mysql -uroot -p123456 #登录（OK）
