一、前提

由于我安装了几次，我就不再讲述报错了，有点打脑壳！！！提前把相关依赖和报错就地解决。

1、所需源码包

mysql-8.0.19.tar.gz boost_1_70_0.tar.gz //安装mysql-8所需要的boost版本rpcsvc-proto-1.4.tar.gz //后面出错所需要的源码包mysql-8.0.19下载地址：http://mirrors.sohu.com/mysql/boost_1_70_0下载地址：https://dl.bintray.com/boostorg/release/1.70.0/source/rpcsvc-proto-1.4下载地址：https://github.com/thkukuk/rpcsvc-proto/releases/download/v1.4/

2、解决依赖

[14:41:21 root@wangzhike ~]#yum install -y cmake ncurses-devel

3、存放位置

软件源代码包存放位置：/usr/local/src
源码包编译安装位置：/usr/local/软件名字

二、编译安装mysql-8.0.19

1、上传源码包

boost_1_70_0.tar.gz mysql-8.0.19.tar.gz rpcsvc-proto-1.4.tar.gz

2、解决rpcsvc-proto-1.4

1）、解压

[17:05:14 root@wangzhike software]#tar -zxf rpcsvc-proto-1.4.tar.gz -C /usr/local/src/

2）、一步安装

[17:09:48 root@wangzhike rpcsvc-proto-1.4]#./configure && make && make install

3、解决boost_1_70_0

[17:13:48 root@wangzhike~]# mkdir -p /usr/local/boost[17:14:05 root@wangzhike~]# cd /usr/local/src[17:15:02 root@wangzhike src]#cp /software/boost_1_70_0.tar.gz /usr/local/boost/[17:26:22 root@wangzhike boost]#tar xf boost_1_70_0.tar.gz////只上传到/usr/local/src/存放目录，解压到当前boost目录

4、创建mysql用户及组

[17:27:46 root@wangzhike ~]#groupadd mysql[17:28:10 root@wangzhike ~]#useradd -g mysql mysql -s /bin/false####创建用户mysql并加入到mysql组，不允许mysql用户直接登录系统[17:28:11 root@wangzhike ~]#mkdir -p /data/mysql ####创建MySQL数据库存放目录[17:29:13 root@wangzhike ~]#chown -R mysql:mysql /data/mysql ####设置MySQL数据库存放目录权限[17:29:31 root@wangzhike ~]#mkdir -p /usr/local/mysql ####创建MySQL安装目录

5、安装mysql-8.0.19

1）、解压

[17:43:24 root@wangzhike software]#tar -zxf mysql-8.0.19.tar.gz -C /usr/local/src/[17:43:47 root@wangzhike software]#cd /usr/local/src/[17:43:53 root@wangzhike src]#cd mysql-8.0.19/

2）、安装

[17:47:01 root@wangzhike mysql-8.0.19]#cmake . \-DCMAKE_INSTALL_PREFIX=/usr/local/mysql \-DINSTALL_DATADIR=/data/mysql -DMYSQL_USER=mysql \-DMYSQL_UNIX_ADDR=/tmp/mysqld.sock -DDEFAULT_CHARSET=utf8 \-DDEFAULT_COLLATION=utf8_general_ci \-DWITH_INNOBASE_STORAGE_ENGINE=1 \-DWITH_EMBEDDED_SERVER=1 \-DFORCE_INSOURCE_BUILD=1 \-DWITH_MYISAM_STORAGE_ENGINE=1 \-DENABLED_LOCAL_INFILE=1 \-DEXTRA_CHARSETS=all \-DWITH_BOOST=/usr/local/boost

若出现以下则没毛病

CMake Warning: Manually-specified variables were not used by the
project:

EXTRA_CHARSETSINSTALL_DATADIRMYSQL_USERWITH_EMBEDDED_SERVER

– Build files have been written to: /usr/local/src/mysql-8.0.19

若出现以下关于rpc.h的错误
Could not find rpc/rpc.h in /usr/include or /usr/include/tirpc

解决方法：

[17:45:47 root@wangzhike mysql-8.0.19]#find / -name rpc.h/usr/local/src/mysql-8.0.19/extra/libevent/include/event2/rpc.h/usr/local/src/mysql-8.0.19/plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/windeps/sunrpc/rpc/rpc.h

####并将/usr/local/src/mysql-8.0.19/plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/windeps/sunrpc/目录下的rpc/rpc.h拷贝到/usr/include/

如下

[17:52:57 root@wangzhike mysql-8.0.19]#cp -a /usr/local/src/mysql-8.0.19/plugin/group_replication/libmysqlgcs/src/bindings/xcom/xcom/windeps/sunrpc/rpc /usr/include/

3）、make && install

[17:55:20 root@wangzhike mysql-8.0.19]#make -j 3 && install
//过程超长且内存不足的会报错

等待等待等待

若报以下错则表示内存不足需要创建分区

+: fatal error: Killed signal terminated program cc1pluscompilation terminated.make[2]: *** [sql/CMakeFiles/sql_gis.dir/build.make:154: sql/CMakeFiles/sql_gis.dir/gis/distance_functor.cc.o] Error 1make[2]: *** Waiting for unfinished jobs....make[1]: *** [CMakeFiles/Makefile2:11144: sql/CMakeFiles/sql_gis.dir/all] Error 2make: *** [Makefile:163: all] Error 2

创建分区：

[19:58:37 root@wangzhike mysql-8.0.19]#dd if=/dev/zero of=/swapfile bs=1k count=20480002048000+0 records in2048000+0 records out2097152000 bytes (2.1 GB, 2.0 GiB) copied, 6.07651 s, 345 MB/s####获取要增加的2G的SWAP文件块[20:10:02 root@wangzhike mysql-8.0.19]#mkswap /swapfilemkswap: /swapfile: insecure permissions 0644, 0600 suggested.Setting up swapspace version 1, size = 2 GiB (2097147904 bytes)no label, UUID=18a4bbb3-75d1-411b-ac0c-c87c63547509####创建SWAP文件[20:10:07 root@wangzhike mysql-8.0.19]#swapon /swapfileswapon: /swapfile: insecure permissions 0644, 0600 suggested.####激活SWAP文件[20:10:12 root@wangzhike mysql-8.0.19]#swapon -sFilename Type Size Used Priority/dev/sda2 partition 2144252 137300 -2/swapfile file 2047996 0 -3#####查看SWAP信息是否正确[20:10:19 root@wangzhike mysql-8.0.19]#echo "/var/swapfile swap swap defaults 0 0" >> /etc/fstab####添加到fstab文件中让系统引导时自动启动

在重新执行make -j 3 && make install ，出现以下画面则没有报错

```bash-- Installing: /usr/local/mysql/man/man1/comp_err.1-- Installing: /usr/local/mysql/man/man1/ibd2sdi.1-- Installing: /usr/local/mysql/man/man1/innochecksum.1-- Installing: /usr/local/mysql/man/man1/lz4_decompress.1-- Installing: /usr/local/mysql/man/man1/my_print_defaults.1-- Installing: /usr/local/mysql/man/man1/myisam_ftdump.1-- Installing: /usr/local/mysql/man/man1/myisamchk.1-- Installing: /usr/local/mysql/man/man1/myisamlog.1-- Installing: /usr/local/mysql/man/man1/myisampack.1-- Installing: /usr/local/mysql/man/man1/mysql.1-- Installing: /usr/local/mysql/man/man1/mysql.server.1-- Installing: /usr/local/mysql/man/man1/mysql_config.1-- Installing: /usr/local/mysql/man/man1/mysql_config_editor.1-- Installing: /usr/local/mysql/man/man1/mysql_secure_installation.1-- Installing: /usr/local/mysql/man/man1/mysql_ssl_rsa_setup.1-- Installing: /usr/local/mysql/man/man1/mysql_tzinfo_to_sql.1-- Installing: /usr/local/mysql/man/man1/mysql_upgrade.1-- Installing: /usr/local/mysql/man/man1/mysqladmin.1-- Installing: /usr/local/mysql/man/man1/mysqlbinlog.1-- Installing: /usr/local/mysql/man/man1/mysqlcheck.1-- Installing: /usr/local/mysql/man/man1/mysqld_multi.1-- Installing: /usr/local/mysql/man/man1/mysqld_safe.1-- Installing: /usr/local/mysql/man/man1/mysqldump.1-- Installing: /usr/local/mysql/man/man1/mysqldumpslow.1-- Installing: /usr/local/mysql/man/man1/mysqlimport.1-- Installing: /usr/local/mysql/man/man1/mysqlman.1-- Installing: /usr/local/mysql/man/man1/mysqlpump.1-- Installing: /usr/local/mysql/man/man1/mysqlshow.1-- Installing: /usr/local/mysql/man/man1/mysqlslap.1-- Installing: /usr/local/mysql/man/man1/perror.1-- Installing: /usr/local/mysql/man/man1/zlib_decompress.1-- Installing: /usr/local/mysql/man/man8/mysqld.8-- Installing: /usr/local/mysql/man/man1/mysqlrouter.1-- Installing: /usr/local/mysql/man/man1/mysqlrouter_passwd.1-- Installing: /usr/local/mysql/man/man1/mysqlrouter_plugin_info.1

三、初始化mysql数据库

1、修改mysql目录权限

[20:37:59 root@wangzhike mysql-8.0.19]#chown -R mysql:mysql /usr/local/mysql[20:42:07 root@wangzhike mysql-8.0.19]#chmod -R 755 /usr/local/mysql

2、初始化mysql

[20:45:07 root@wangzhike ~]#cd /usr/local/mysql/[20:46:43 root@wangzhike mysql]#./bin/mysqld --initialize --user=mysql --datadir=/usr/local/mysql/data --character-set-server=utf82020-04-14T12:47:13.718724Z 0 [System] [MY-013169] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.19) initializing of server in progress as process 98932020-04-14T12:47:13.719367Z 0 [Warning] [MY-013242] [Server] --character-set-server: 'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release.

3、修改配置文件
mysql 8.0.x默认没有配置文件，我们自己创建一个。

[20:49:41 root@wangzhike mysql]#vi /usr/local/mysql/my.cnf添加以下内容：[client]port=3306socket=/tmp/mysql.sock[mysqld]port=3306user = mysqlsocket=/tmp/mysql.socktmpdir = /tmpkey_buffer_size=16Mmax_allowed_packet=128Mdefault_authentication_plugin=mysql_native_passwordopen_files_limit = 60000explicit_defaults_for_timestampserver-id = 1character-set-server = utf8federatedmax_connections = 1000max_connect_errors = 100000interactive_timeout = 86400wait_timeout = 86400sync_binlog=0back_log=100default-storage-engine = InnoDBlog_slave_updates = 1[mysqldump]quick[client]password="123456"[mysqld-8.0]sql_mode=TRADITIONAL[mysqladmin]force[mysqld]key_buffer_size=16Mservice mysqld restart

：wq！保存退出
注意，service mysqld restart 这一句一定写上，默认密码为123456

其他操作

[20:53:05 root@wangzhike mysql]#ln -s /usr/local/mysql/my.cnf /etc/my.cnf#添加到/etc目录的软连接[20:53:12 root@wangzhike mysql]#cd[20:53:13 root@wangzhike ~]#cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld#把Mysql加入系统启动[20:53:21 root@wangzhike ~]#chmod 755 /etc/init.d/mysqld#增加执行权限[20:53:28 root@wangzhike ~]#chkconfig mysqld on#加入开机启动

4、编辑文件

[20:53:39 root@wangzhike ~]#vi /etc/rc.d/init.d/mysqld####找到basedir=并修改为/usr/local/mysql####找到datadir=并修改为/data/mysqlbasedir=/usr/local/mysql #MySQL程序安装路径datadir=/data/mysql #MySQl数据库存放目录

5、开机启动成功

[20:54:32 root@wangzhike ~]#service mysqld startStarting MySQL.Logging to '/data/mysql/wangzhike.err'.. SUCCESS! #启动成功

6、添加变量

[20:54:44 root@wangzhike ~]#vi /etc/profile在最后一行添加export PATH=$PATH:/usr/local/mysql/bin[20:55:37 root@wangzhike ~]#source /etc/profile #使配置立刻生效

7、添加软连接

[20:55:44 root@wangzhike ~]#ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql[20:55:57 root@wangzhike ~]#ln -s /usr/local/mysql/include/mysql /usr/include/mysql####以上为把myslq的库文件链接到系统默认的位置[20:56:02 root@wangzhike ~]#mkdir /var/lib/mysql[20:56:14 root@wangzhike ~]#ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

8、启动mysql

[21:40:14 root@wangzhike ~]#mysql -uroot -p123456Welcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 9Server version: 8.0.19 Source distributionCopyright (c) 2000, 2020, Oracle and/or its affiliates.

Type '\c' to clear the current input statement.mysql>

则表示登陆成功。
