卸载mariadb
# rpm -qa mariadb*
mariadb-libs-5.5.44-2.el7.centos.x86_64
# rpm -e --nodeps mariadb-libs-5.5.44-2.el7.centos.x86_64
一、对于centos 7 安装mySql依赖项
yum install gcc gcc-c++ make cmake bison bison-devel ncurses ncurses-devel libaio-devel perl autoconf automake zlib* fiex* libxml* libmcrypt* libtool-ltdl-devel* 二、创建用户
设置MySQL用户和组
- 新增mysql用户组
groupadd mysql - 新增mysql用户
useradd -r -g mysql mysql 三、新建MySQL所需要的目录
新建mysql安装目录
-p /mysql/app
- 新建mysql数据库数据文件目录
mkdir -p /mysql/app/data- 新建mysql.sock数据库链接文件目录
mkdir -p /mysql/app/tmp- 新建mysql日志存放目录
mkdir -p /mysql/app/logs- 新建mysql 配置文件目录
mkdir -p /mysql/app/etc四、上传源码文件
- mysql-5.7.18.tar.gz
- 下载地址
- http://120.198.244.60:9999/mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.18.tar.gz
解压编译
cmake -DCMAKE_INSTALL_PREFIX=/mysql/app -DMYSQL_DATADIR=/mysql/app/data -DSYSCONFDIR=/mysql/app/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/mysql/app/tmp/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost参数解析：
- CMAKE_INSTALL_PREFIX：指定MySQL程序的安装目录，默认/usr/local/mysql
- DEFAULT_CHARSET：指定服务器默认字符集，默认latin1
- DEFAULT_COLLATION：指定服务器默认的校对规则，默认latin1_general_ci
- ENABLED_LOCAL_INFILE：指定是否允许本地执行LOAD DATA INFILE，默认OFF
- WITH_COMMENT：指定编译备注信息
- WITH_xxx_STORAGE_ENGINE：指定静态编译到mysql的存储引擎，MyISAM，MERGE，MEMBER以及CSV四种引擎默认即被编译至服务器，不需要特别指定。
- WITHOUT_xxx_STORAGE_ENGINE：指定不编译的存储引擎
- SYSCONFDIR：初始化参数文件目录
- MYSQL_DATADIR：数据文件目录
- MYSQL_TCP_PORT：服务端口号，默认3306
- MYSQL_UNIX_ADDR：socket文件路径，默认/tmp/mysql.sock
- DDOWNLOAD_BOOST=1 ：下载boost库
- DWITH_BOOST=/usr/local/boost 安装boost库
编译安装
make && make install- 中间大概2个小时
## 出错的情况下 需要重新编译才执行 否则不用操作 下面这两条命令
make clean
rm -f CMakeCache.txt五、创建配置文件my.cnf
- 编译安装不存在my.cnf
- 手动创建my.cnf
vi /mysql/app/etc/my.cnf[client]
port = 3306
socket = /mysql/tmp/mysqld.sock
[mysqld]

#character_set_server=utf8六、授权用户
chown -R mysql:mysql /mysql/app
chown -R mysql:mysql /mysql/app/data
chmod 1777 /mysql/app/tmp七、设置环境变量
echo 'export PATH=/mysql/app/bin:$PATH' >>/etc/profilesource !$八、创建服务启动脚本，添加开机启动
cp /mysql/app/support-files/mysql.server/etc/init.d/mysqld
chmod +x /etc/init.d/mysqld //给脚本添加执行权限
vi /etc/init.d/mysqld
//服务启动脚本要修改以下两个参数
basedir=/mysql/app //MySQL安装目录
datadir= /mysql/app/data //数据存放目录
conf=/mysql/etc/my.cnf //配置文件路径
chkconfig mysqld on //添加开机启动九、初始化数据库
/mysql/app/bin/mysqld --initialize --user=mysql --basedir=/mysql/app --datadir=/mysql/app/data/- /mysql/app/logs/mysql-error.log
- 记录临时密码
十、重启mysql
service mysqld restart十一、登陆
- mysql -u root -p
- 输入临时密码
- 修改root密码
- SET PASSWORD = PASSWORD('新密码');
- ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
- flush privileges;
