mysql 源码安装以及多实例
一、源码安装mysql-5.5.32
1、编译安装CMAKE
[root@Oldboy tools]# tar zxvf cmake-3.5.2.tar.gz
[root@Oldboy tools]# cd cmake-3.5.2
[root@Oldboy cmake-3.5.2]# ./configure && make && make install
2、编译安装mysql-5.5.32
[root@Oldboy tools]# mkdir /application
[root@Oldboy tools]# yum install ncurses-devel -y
[root@Oldboy tools]# groupadd mysql
[root@Oldboy tools]# useradd mysql -s /sbin/nologin -M -g mysql
[root@Oldboy tools]# tar zxvf mysql-5.5.32.tar.gz
[root@Oldboy tools]# cd mysql-5.5.32cmake . -DCMAKE_INSTALL_PREFIX=/application/mysql-5.5.32 \
-DMYSQL_DATADIR=/application/mysql-5.5.32/data \
-DMYSQL_UNIX_ADDR=/application/mysql-5.5.32/tmp/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DEXTRA_CHARSETS=gbk,gb2312,utf8,ascii \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITHOUT_PARTITION_STORAGE_ENGINE=1 \
-DWITH_FAST_MUTEXES=1 \
-DWITH_ZLIB=bundled \

make && make install[root@Oldboy mysql-5.5.32]# ln -s /application/mysql-5.5.32 /application/mysql
[root@Oldboy mysql-5.5.32]# cp support-files/my-small.cnf /etc/my.cnf
[root@Oldboy mysql-5.5.32]# cp support-files/mysql.server /etc/init.d/mysqld
[root@Oldboy mysql-5.5.32]# chmod +x /etc/init.d/mysqld
[root@Oldboy mysql-5.5.32]# /application/mysql/scripts/mysql_install_db --basedir=/application/mysql/ --datadir=/application/mysql/data/ --user=mysql （初始化mysql）
[root@Oldboy mysql-5.5.32]# echo "export PATH="/application/mysql/bin:$PATH"" >> /etc/profile （增加mysql环境变量）
[root@Oldboy mysql-5.5.32]# source /etc/profile
[root@Oldboy mysql-5.5.32]# /etc/init.d/mysqld start
Starting MySQL.... SUCCESS!
[root@Oldboy mysql-5.5.32]# netstat -npult|grep mysqld
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 21595/mysqld
[root@Oldboy ~]# /etc/init.d/mysqld stop二、部署mysql多实例
1、创建mysql 多实例 3306 和 3307
[root@Oldboy ~]# mkdir -pv /data/{3306,3307}/data (创建mysql多实例目录)
[root@Oldboy /]# cd / && unzip data.zip （解压my.cnf 和 mysql启动脚本）
[root@Oldboy /]# chown -R mysql.mysql /data
[root@Oldboy /]# find /data/ -type f -name "mysql"|xargs chmod +x
[root@Oldboy /]# cd /application/mysql/scripts/
[root@Oldboy scripts]# ./mysql_install_db --basedir=/application/mysql --datadir=/data/3306/data --user=mysql (初始化mysql3306)
[root@Oldboy scripts]# ./mysql_install_db --basedir=/application/mysql --datadir=/data/3307/data --user=mysql (初始化mysql3307)
[root@Oldboy scripts]# /data/3306/mysql start
Starting MySQL...
[root@Oldboy scripts]# /data/3307/mysql start
Starting MySQL...
[root@Oldboy scripts]# netstat -nptul|grep mysqld
tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 23219/mysqld
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 22501/mysqld
2、连接mysql多实例
[root@Oldboy scripts]# mysql -uroot -p -S /data/3306/mysql.sock
连接mysql多实例时，需要使用 -S 指定mysql.sock
修改mysql密码后，需要修改多实例中的mysql启动脚本中指定的密码，否则无法启动/关闭/重启
3、增加一个mysql 3308
[root@Oldboy data]# cp -a /data/3306 /data/3308
[root@Oldboy 3308]# rm -rf mysql-bin.* mysqld.pid mysql_oldboy3306.err mysql.sock
[root@Oldboy 3308]# cd /data/3308/
[root@Oldboy 3308]# sed -i.bak s#3306#3308#g mysql
[root@Oldboy 3308]# sed -i.bak s#3306#3308#g my.cnf
[root@Oldboy 3308]# /data/3308/mysql start
Starting MySQL...
[root@Oldboy 3308]# netstat -npult|grep mysqld
tcp 0 0 0.0.0.0:3307 0.0.0.0:* LISTEN 23219/mysqld
tcp 0 0 0.0.0.0:3308 0.0.0.0:* LISTEN 24017/mysqld
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 22501/mysqld
4、查看多实例中的 my.cnf 和 mysql启动脚本
/data/{3306,3307} 是mysql多实例的安装目录
/application/mysql 是mysql的原始安装目录(1) [root@Oldboy 3308]# cat /data/3306/my.cnf
