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
代码语言：javascript复制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
代码语言：javascript复制[14:41:21 root@wangzhike ~]#yum install -y cmake ncurses-devel3、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
代码语言：javascript复制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
代码语言：javascript复制[17:05:14 root@wangzhike software]#tar -zxf rpcsvc-proto-1.4.tar.gz -C /usr/local/src/2）、一步安装
代码语言：javascript复制[17:09:48 root@wangzhike rpcsvc-proto-1.4]#./configure && make && make install3、解决boost_1_70_0
代码语言：javascript复制[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
代码语言：javascript复制[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
代码语言：javascript复制[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
代码语言：javascript复制[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_CHARSETS INSTALL_DATADIR MYSQL_USER WITH_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：
代码语言：javascript复制[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
代码语言：javascript复制 : fatal error: Killed signal terminated program cc1plus
compilation terminated.
make[2]: *** [sql/CMakeFiles/sql_gis.dir/build.make:154: sql/CMakeFiles/sql_gis.dir/gis/distance_functor.cc.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [CMakeFiles/Makefile2:11144: sql/CMakeFiles/sql_gis.dir/all] Error 2
make: *** [Makefile:163: all] Error 2创建分区：
代码语言：javascript复制[19:58:37 root@wangzhike mysql-8.0.19]#dd if=/dev/zero of=/swapfile bs=1k count=2048000
2048000 0 records in
2048000 0 records out
2097152000 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 /swapfile
mkswap: /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 /swapfile
swapon: /swapfile: insecure permissions 0644, 0600 suggested.
####激活SWAP文件
[20:10:12 root@wangzhike mysql-8.0.19]#swapon -s
Filename 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

1、修改mysql目录权限
代码语言：javascript复制[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/mysql2、初始化mysql
代码语言：javascript复制[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=utf8
2020-04-14T12:47:13.718724Z 0 [System] [MY-013169] [Server] /usr/local/mysql/bin/mysqld (mysqld 8.0.19) initializing of server in progress as process 9893
2020-04-14T12:47:13.719367Z 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. Please consider using UTF8MB4 in order to be unambiguous.
2020-04-14T12:47:14.855541Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: rUG-.8kdw<1f
####生成mysql系统数据库。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。
代码语言：javascript复制[20:49:41 root@wangzhike mysql]#vi /usr/local/mysql/my.cnf
添加以下内容：
[client]
port=3306
socket=/tmp/mysql.sock
[mysqld]
port=3306
user = mysql
socket=/tmp/mysql.sock
tmpdir = /tmp
key_buffer_size=16M
max_allowed_packet=128M
default_authentication_plugin=mysql_native_password
open_files_limit = 60000
explicit_defaults_for_timestamp
server-id = 1
character-set-server = utf8
federated
max_connections = 1000
max_connect_errors = 100000
interactive_timeout = 86400
wait_timeout = 86400
sync_binlog=0
back_log=100
default-storage-engine = InnoDB
log_slave_updates = 1
[mysqldump]
quick
[client]
password="123456"
[mysqld-8.0]
sql_mode=TRADITIONAL
[mysqladmin]
force
[mysqld]
key_buffer_size=16M
service 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
代码语言：javascript复制[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
代码语言：javascript复制[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/mysql
basedir=/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
代码语言：javascript复制[20:54:32 root@wangzhike ~]#service mysqld start
Starting MySQL.Logging to '/data/mysql/wangzhike.err'.
. SUCCESS! #启动成功6、添加变量
代码语言：javascript复制[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
代码语言：javascript复制[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.sock8、启动mysql
代码语言：javascript复制[21:40:14 root@wangzhike ~]#mysql -uroot -p123456
