centos mysql-5.6.34 编译安装:
准备工作:
yum install gcc gcc-c++ ncurses-devel perl
安装cmake:
yum install cmake
或源码安装:
wget http://www.cmake.org/files/v2.8/cmake-2.8.10.2.tar.gz
tar -xzvf cmake-2.8.10.2.tar.gz
cd cmake-2.8.10.2
./bootstrap ; make ; make install
cd ~
新增mysql用户组:
groupadd mysql
新增mysql用户:
useradd -r -g mysql mysql
新建mysql安装目录:
mkdir -p /usr/local/mysql
新建mysql数据库数据文件目录:
mkdir -p /data/mysqldb
wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.34.tar.gz
tar -zxvf mysql-5.6.34.tar.gz
cd mysql-5.6.34
从mysql5.5起,mysql源码安装开始使用cmake了,设置源码编译配置脚本:
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DMYSQL_DATADIR=/data1/mysqldb -DMYSQL_TCP_PORT=3306 -DENABLE_DOWNLOADS=1
make -j4
make install
修改mysql目录所有者和组:
cd /usr/local/mysql
chown -R mysql:mysql ./
cd /data/mysqldb
chown -R mysql:mysql ./
初始化mysql数据库:
cd /usr/local/mysql
scripts/mysql_install_db –user=mysql –datadir=/data/mysqldb
复制mysql服务启动配置文件:
cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
giedt /etc/my.cnf
[client]
port = 3306
socket = /var/lib/mysql/mysql.sock
[mysqld]
user = mysql
port = 3306
socket = /var/lib/mysql/mysql.sock
basedir = /usr/local/mysql
datadir = /data1/mysqldb
log-error = /data/mysqldb/mysql_error.log
pid-file = /data/mysqldb/mysql.pid
复制mysql服务启动脚本及加入PATH路径:
cp support-files/mysql.server /etc/init.d/mysqld
vim /etc/profile
PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH
export PATH
source /etc/profile
启动mysql服务并加入开机自启动(可选这个步骤,以后可以自己启动的):
service mysqld start
chkconfig –level 35 mysqld on
检查mysql服务是否启动:
netstat -tulnp | grep 3306
mysql -u root -p
修改MySQL用户root的密码:
mysqladmin -u root password ‘123456’
注:也可运行安全设置脚本,修改MySQL用户root的密码,同时可禁止root远程连接,移除test数据库和匿名用户:
/usr/local/mysql/bin/mysql_secure_installation
MySQL问题解决:-bash:mysql:command not found
因为mysql命令的路径在/usr/local/mysql/bin下面,所以你直接使用mysql命令时,
系统在/usr/bin下面查此命令,所以找不到了
解决办法是:
ln -s /usr/local/mysql/bin/mysql /usr/bin 做个链接即可
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/usr/local/mysql/mysql.sock’ (2)
1、先查看 /etc/rc.d/init.d/mysqld status 看看mysql服务是否已经启动.
另外看看是不是权限问题.
$service mysqld start
或
$service mysql start
–我开始遇到的就是因为服务没启动,因为第一次玩mysql不是很熟悉,呵呵。
2、确定你的mysql.sock是不是在那个位置,
mysql -u 你的mysql用户名 -p -S /var/lib/mysql/mysql.sock
如果错啦,就修改/etc/my.cnf:
[client]
socket = /var/lib/mysql/mysql.sock
[mysqld]
socket = /var/lib/mysql/mysql.sock
3、如果是权限问题,则先改变权限 #chown -R mysql:mysql /var/lib/mysql
[root@localhost ~]
# /etc/init.d/mysqld start
启动 MySQL: [ 确定 ]
[root@localhost ~]
# mysql -uroot -p
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock’ (2)
原因是,/var/lib/mysql 的访问权限问题。
shell> chown -R mysql:mysql /var/lib/mysql
接着启动服务器
shell> /etc/init.d/mysql start
服务器正常启动后察看 /var/lib/mysql 自动生成mysql.sock文件。
4、修改/etc/my.conf:
[mysqld]
datadir=/usr/local/mysql/data
socket=/var/lib/mysql/mysql.sock
[mysql.server]
user=mysql
basedir=/usr/local/mysql
If there is not currently a section called [client], add one at the bottom of the file and copy the socket= line under the [mysqld] section such as:
[client]
socket=/var/lib/mysql/mysql.sock
如果发现问题依旧,尝试运行/etc/init.d/mysql start报错:Starting MySQLCouldn’t find MySQL manager or server
如是mysqld服务没启,运行/usr/local/mysql/bin/mysqld_safe &
