源码安装MySQL
1.安装依赖:
# yum -y install ncurses ncurses-devel openssl-devel bison gcc gcc-c++ make cmake
下载MySQL:
wget https://repo.huaweicloud.com/mysql/Downloads/MySQL-5.7/mysql-5.7.35.tar.gz (华为镜像站)
还需安装boost包:
# wget http://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
安装MySQL:
# groupadd mysql # useradd -r -g mysql -s /bin/false mysql # tar xvf mysql-5.7.19.tar.gz 注意目录权限 # cd mysql-5.7.19 [root@mysql3 mysql-5.7.19]# pwd /root/mysql-5.7.19 [root@mysql3 mysql-5.7.19]# tar xf boost_1_59_0.tar.gz (注意包的位置)
2.配置
[root@mysql-5.7.17 ~]#
cmake .
-DWITH_BOOST=boost_1_59_0/
-DCMAKE_INSTALL_PREFIX=/usr/local/mysql
-DSYSCONFDIR=/etc
-DMYSQL_DATADIR=/usr/local/mysql/data
-DINSTALL_MANDIR=/usr/share/man
-DMYSQL_TCP_PORT=3306
-DMYSQL_UNIX_ADDR=/tmp/mysql.sock
-DDEFAULT_CHARSET=utf8
-DEXTRA_CHARSETS=all
-DDEFAULT_COLLATION=utf8_general_ci
-DWITH_READLINE=1
-DWITH_SSL=system
-DWITH_EMBEDDED_SERVER=1
-DENABLED_LOCAL_INFILE=1
-DWITH_INNOBASE_STORAGE_ENGINE=1
常见错误
-DWITH_BOOST=boost_1_59_0
如果没有提前准备,可以使用下面的参数自己装。
-DDOWNLOAD_BOOST=1
-DWITH_READLINE=1 5.6被移除
如果cmake失败,请将CMakeCache.txt缓存移除
3.编译安装:
# make 等待半小时左右
# make install
初始化:
# cd /usr/local/mysql # mkdir mysql-files # chown -R mysql.mysql . 注意目录名称 # bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data 保存临时密码。(或者skip-grant-tables) x/dwiQ2<l:hb # bin/mysql_ssl_rsa_setup --datadir=/usr/local/mysql/data
创建日志目录及pid目录
mkdir -p /var/run/mysql
chown -R mysql:mysql /var/run/mysql
mkdir -p /var/log/mysql
chown -R mysql:mysql /var/log/mysql
mkdir -p /var/lib/mysql
chown -R mysql:mysql /var/lib/mysql 建立MySQL配置文件my.cnf
# vim /etc/my.cnf [root@mysql1 mysql]# vim /etc/my.cnf [mysqld] basedir=/usr/local/mysql datadir=/usr/local/mysql/data
socket=/var/lib/mysql/mysql.sock
pid=/var/run/mysql/mysql.pid
log-error=/var/log/mysql/mysql.log
[client]
port=3306
socket=/var/lib/mysql/mysql.sock
4.启动MySQL:
vim /usr/lib/systemd/system/mysql.service [Unit] Description=mysql After=network.target remote-fs.target nss-lookup.target [Service] Type=forking ExecStart=/usr/local/mysql/support-files/mysql.server start ExecReload=/usr/local/mysql/support-files/mysql.server restart ExecStop=/usr/local/mysql/support-files/mysql.server stop PrivateTmp=true [Install] WantedBy=multi-user.target
设置环境变量:
echo 'PATH=$PATH':/usr/local/mysql/bin >> /etc/profile source /etc/profile
CentOS6:
# chkconfig --add mysqld 添加mysql服务
# chkconfig mysqld on 开机自动启动mysql服务
# service mysqld start
CentOS7:
#systemctl start mysqld
#systemctl enable mysqld
查看mysql进程
# ps aux |grep mysqld 首次登陆需要密码 # mysql -u root -p '密码' 登陆有问题吗? # /usr/local/mysql/bin/mysql -u root -p'x/dwiQ2<l:hb' 不要忘了配置新密码。 # /usr/local/mysql/bin/mysqladmin -u root -p 'x/dwiQ2<l:hb' password 'Qing@123' show databases; 看到库即可。
