CentOS编译安装MySQL的教程网上有很多，基本上大同小异。但是安装软件有时就可能因为一个细节安装失败，本篇文章详细的为大家讲解一下CentOS 7编译安装MySQL 8.0具体方法。
0.前期准备条件
•查看linux的版本
[root@mysql etc]# cat /etc/RedHat-release
CentOS Linux release 7.3.1611 (Core)
•Could NOT find Curses
yum install ncurses-devel
•Bison executable not found in PATH
yum install bison
备注： 安装过程中会缺少基础包，本实例环境缺少上述包，先提前安装相应的包
1.cmake的源编译安装
[root@db software]# nohup tar zxvf cmake-3.11.1.tar.gz &
[root@db software]# cd cmake-3.11.1
[root@db cmake-3.11.1]# ./configure
[root@localhost cmake-3.0.1]# gmake && make install
2.wolfssl包的部署安装[可选项]
*. 从wolfssl.com网站下载wolfssl-3.13.0.zip压缩包
*. 解压至/data/software/mysql-8.0.11/extra/wolfssl-3.13.0目录中。
*. cd extra/wolfssl-3.13.0/IDE/MYSQL
*. 执行do.sh脚本
*. use -DWITH_SSL=wolfssl for CMake
3.openssl和openssl-devel[本实验使用的是system ssl]
yum install –y openssl openssl-devel
4.mysql的编译安装
[root@mysql software]#tar zxvf mysql-8.0.11.tar.gz
[root@mysql software]# cd mysql-8.0.11/
[root@mysql software]# mkdir Zdebug
[root@mysql software]# cd Zdebug
cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DENABLED_LOCAL_INFILE=ON \
-DWITH_INNODB_MEMCACHED=ON \
-DWITH_SSL=system \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=1 \
-DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
-DWITH_ARCHIVE_STORAGE_ENGINE=1 \
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1 \
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1 \
-DCOMPILATION_COMMENT="zsd edition" \
-DDOWNLOAD_BOOST=1 \
-DWITH_BOOST=/tmp \
-DMYSQL_UNIX_ADDR=/data/mysqldata/3306/mysql.sock \
-DSYSCONFDIR=/data/mysqldata/3306 > /data/software/mysql-8.0.11/Zdebug/mysql_cmake80.log 2>&1
出现下列日志:
............
-- Configuring done
-- Generating done
-- Build files have been written to: /data/software/mysql-8.0.11/Zdebug
............
说明编译成功，其中-DWITH_SSL=system用的是linux操作系统的openssl，需要安装openssl和openssl-devel包，才可以被编译
如果需要编译安装快速，可以运用多线程加快编译安装，命令如下:
make -j 12
make install
•MySQL 8.0的软件目录结构
[root@mysql Zdebug]# cd /usr/local/mysql/
[root@mysql mysql]# ls -l
total 612
drwxr-xr-x. 2 root root 4096 May 16 14:20 bin
drwxr-xr-x. 2 root root 55 May 16 14:20 docs
drwxr-xr-x. 3 root root 266 May 16 14:20 include
drwxr-xr-x. 4 root root 173 May 16 14:20 lib
-rw-r--r--. 1 root root 301518 Apr 8 14:44 LICENSE
-rw-r--r--. 1 root root 301518 Apr 8 14:44 LICENSE-test
drwxr-xr-x. 4 root root 30 May 16 14:20 man
drwxr-xr-x. 10 root root 4096 May 16 14:21 mysql-test
-rw-r--r--. 1 root root 687 Apr 8 14:44 README
-rw-r--r--. 1 root root 687 Apr 8 14:44 README-test
drwxr-xr-x. 28 root root 4096 May 16 14:21 share
drwxr-xr-x. 2 root root 90 May 16 14:21 support-files
5.创建mysql用户&并修改相关文件
[root@mysql mysql]# groupadd mysql
[root@mysql mysql]# useradd -g mysql mysql
6.设置用户操作系统资源的限制
[root@localhost cmake-3.0.1]# vi /etc/security/limits.conf
mysql soft nproc 65536
mysql hard nproc 65536
mysql soft nofile 65536
mysql hard nofile 65536
验证limit是否生效
[root@mysql ~]# su - mysql
[mysql@mysql ~]$ ulimit -a
日志如下:
open files (-n) 65536
max user processes (-u) 65536
............
7.创建MySQL数据目录及赋予相应权限
#cd /data/
#mkdir -p /data/mysqldata/{3306/{data,tmp,binlog,innodb_ts,innodb_log},backup,scripts}
#chown -R mysql:mysql mysqldata
#su - mysql
8.配置my.cnf文件
$vi /data/mysqldata/3306/my.cnf
[client]
port = 3306
socket = /data/mysqldata/3306/mysql.sock
# The MySQL server
[mysqld]
port = 3306
user = mysql
socket = /data/mysqldata/3306/mysql.sock
pid-file = /data/mysqldata/3306/mysql.pid

9.初始化MySQL数据库
$/usr/local/mysql/bin/mysqld --defaults-file=/data/mysqldata/3306/my.cnf --initialize --user=mysql
10.启动mysql服务
$/usr/local/mysql/bin/mysqld_safe --defaults-file=/data/mysqldata/3306/my.cnf --user=mysql &
11.登陆数据库
备注:密码来自于error log日志，明细如下:
2018-05-16T07:17:57.335486Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: j
local/mysql/bin/mysql -uroot -p
'j
12.数据库一些基本权限配置
•修改root账号密码:
ALTER USER 'root'@'localhost' IDENTIFIED WITH sha256_password BY 'zsd@7101' PASSWORD EXPIRE INTERVAL 360 DAY;
•查看目前的用户账号
(root@localhost) [(none)]> select user,host from mysql.user;
+------------------+-----------+
| user | host |
+------------------+-----------+
| mysql.infoschema | localhost |
| mysql.session | localhost |
| mysql.sys | localhost |
| root | localhost |
+------------------+-----------+
