- 如果有卸载官方自带的安装包
rpm -qa | grep -i mysql
rpm -qa | grep -i mariadb
rpm -e xxxx
#注:如上命令删除不成功,有别的软件依赖无法删除时,如下操作:
yum remove xxxx
或
rpm -e --nodeps xxxx
```
2. 关闭seLinux
一、查看SELinux状态命令:
1、/usr/sbin/sestatus -v ##如果SELinux status参数为enabled即为开启状态
SELinux status: enabled
2、getenforce ##也可以用这个命令检查
二、关闭SELinux方法:
1、临时关闭(不用重启机器):
代码如下:
setenforce 0 #设置SELinux 成为 permissive 模式 放任的 关闭
#setenforce 1 设置SELinux 成为 enforcing 模式 强制执行 打开
2、修改配置文件需要重启机器:
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled
重启机器即可
3.下载源码包安装依赖
// 初始化目录
mkdir -p /data/mysql/data
mkdir -p /data/mysql/tmp
mkdir -p /data/mysql/binlog
mkdir -p /data/mysql/logs
mkdir -p /data/boost
groupadd mysql
useradd mysql -s /sbin/nologin -M -g mysql
-s /sbin/nologin 用户不能登录系统
-M 不创建用户的home家目录
-g 指定用户登录组的gid或组名
id mysql
// 下载源码包 并且解压
cd /data
wget https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.30.tar.gz
yum -y install gcc gcc-c++ glibc automake autoconf libtool make openssl openssl-devel ncurses ncurses-devel cmake
// 下载boost到/data/boost 后面的编译参数会用到
cd /data/boost
wget http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
cd /data/mysql-5.7.30
cmake -DCMAKE_INSTALL_PREFIX=/data/mysql -DMYSQL_DATADIR=/data/mysql/data -DMYSQL_UNIX_ADDR=/data/mysql/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DEXTRA_CHARSETS=all -DENABLED_LOCAL_INFILE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_EXAMPLE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_ZLIB=bundled -DWITH_EMBEDDED_SERVER=1 -DSYSCONFDIR=/etc -DMYSQL_TCP_PORT=3306 -DWITH_SSL=yes -DWITH_DEBUG=0 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/data/boost
//如果编译出现错误,请先删除CMakeCache.txt后,检查环境后再重新编译:
//rm -rf CMakeCache.txt
make install
// 添加环境变量
echo ‘export PATH=/data/mysql/bin:$PATH‘ >> /etc/profile
source /etc/profile
chown -R mysql:mysql /data/mysql/
vi /etc/my.cnf
[client]
port = 3306
socket = /data/mysql/tmp/mysql.sock
default-character-set = utf8
[mysqld]
port = 3306
user = mysql
basedir = /data/mysql
datadir = /data/mysql/data
pid-file = /data/mysql/mysqld.pid
socket = /data/mysql/tmp/mysql.sock
tmpdir = /data/mysql/tmp

chown mysql:mysql /etc/my.cnf
- 初始化数据库,进入到安装目录
// 数据库初始化
cd /data/mysql/
./bin/mysqld --initialize-insecure --user=mysql --basedir=/data/mysql --datadir=/data/mysql/data
// mysql实例开启ssl连接,进入到安装目录 https://www.cnblogs.com/mysql-dba/p/7061300.html 解释 生产环境内网一半不开启
cd /data/mysql/
./bin/mysql_ssl_rsa_setup --initialize-insecure --user=mysql --basedir=/data/mysql --datadir=/data/mysql/data
cd /data/mysql/data/
chmod +r server-key.pem
// 设置开机自启动
cp /data/mysql/support-files/mysql.server /etc/init.d/mysqld
systemctl daemon-reload
systemctl enable mysqld.service
chkconfig mysqld on
systemctl start mysqld
systemctl status mysqld
// 第一次登录不需要密码
mysql -uroot -p
select user,host from mysql.user;
set password for ‘mysql.session‘@‘localhost‘ = password(‘123456‘);
set password for ‘mysql.sys‘@‘localhost‘ = password(‘123456‘);
set password for ‘root‘@‘localhost‘ = password(‘123456‘);
flush privileges;
// 授权
grant all privileges on *.* to root@‘%‘ identified by ‘123456‘ with grant option;
select version();
