编译安装
1.下载源码包
官网:https://downloads.mysql.com/archives/community/
2.上传下载的源码包mysql-community-5.7.29-1.el7.src.rpm到linux家目录
3.新建用户mysql
useradd -s /sbin/nologin mysql
4.解决软件的依赖关系
yum install cmake ncurses-devel gcc gcc-c++ vim lsof bzip2 openssl-devel -y
5.安装源码的rpm包,得到真正的源代码
rpm -ivh mysql-community-5.7.29-1.el7.src.rpm
6.进入/root/rpmbuild目录
cd /root/rpmbuild/SOURCES
7.解压真正的源码包
tar xf mysql-5.7.29.tar.gz
tar xf boost_1_59_0.tar.bz2
8.将boost包移动到mysql解压的包里
mv boost_1_59_0 mysql-5.7.29
9.切换到mysql-5.7.29目录下
cd mysql-5.7.29
10.编译前的配置
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/sc_mysql -DMYSQL_DATADIR=/data/mysql -DSYSCONFDIR=/etc -DMYSQL_USER=mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=boost_1_59_0
11.编译和编译安装
make -j 2 && make install
初始化操作
1.关闭防火墙
service firewalld stop
systemctl disable firewalld
2.关闭selinux
setenforce 0 (临时关闭selinux)
sed -i ‘s/enforcing/disabled/’ /etc/selinux/config (永久关闭selinux)
3.初始化操作
mkdir /data/mysql -p
chown mysql:mysql /data/mysql/
chmod 750 /data/mysql/
cd /usr/local/sc_mysql/bin
./mysqld --initialize --user=mysql --basedir=/usr/local/sc_mysql/ --datadir=/data/mysql &>passwd.txt
4.获得临时密码
tem_passwd=$(cat passwd.txt |grep “temporary”|awk ‘{print $NF}’)
5.修改环境变量,添加我们编译安装的MySQL的可执行命令的路径
echo “PATH=$PATH:/usr/local/sc_mysql/bin” >>/root/.bashrc
PATH=$PATH:/usr/local/sc_mysql/bin
6.复制mysql提供的启动mysqld服务的脚本到/etc/init.d目录下–>复制mysqld的启动脚本
cp …/support-files/mysql.server /etc/init.d/mysqld
7.生成/etc/my.cnf配置文件
cat >/etc/my.cnf <<EOF
[mysqld_safe]
[client]
socket=/data/mysql/mysql.sock
[mysqld]
socket=/data/mysql/mysql.sock
port = 3306
open_files_limit = 8192
innodb_buffer_pool_size = 512M
[mysql]
auto-rehash
prompt=\u@\d \R:\m mysql>
EOF
8.启动mysqld服务
service mysqld start
9.初次修改密码需要使用–connect-expired-password 选项,登录重新设置初始密码为Sanchuang123#
mysql -uroot -p$tem_passwd --connect-expired-password -e “set password=‘Sanchuang123#’;”
10.验证密码是否设置成功
mysql -uroot -pSanchuang123# -e ‘show databases;’ && echo “database is installed success”
一键安装脚本
