代码语言：javascript复制groupadd mysql --创建mysql用户组组
useradd -r -g mysql mysql --创建mysql用户并添加到mysql用户组中
chown -R mysql.mysql mysql/ --将mysql目录访问权限赋为myql用户4.创建MySQL配置文件
代码语言：javascript复制cat >>/etc/my.cnf <<EOF #写入配置文件
[client]
port = 3306
socket = /tmp/mysql.sock
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/tmp/mysql.sock
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
#不区分大小写
lower_case_table_names = 1
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

不然修改密码之后密码会过期，会提示让你重新设置密码
You must reset your password using ALTER USER statement before executing this statement.
/usr/local/mysql/bin/mysql -uroot -p #登录MySQL
use mysql #切换MySql数据库
update mysql.user set authentication_string =password('root'), host = '%' where user = 'root'; #修改MySQL密码
flush privileges;9.将MySQL加入环境变量
代码语言：javascript复制echo 'PATH=/usr/local/mysql/bin:$PATH' >>/etc/profile #将MySQL二进制文件加入环境变量
ln -s usr/local/mysql/support-files/mysql.server /usr/local/mysql/bin/ 将MySQL的启动文件软连接到MySQL的环境变量中10.进入数据库并创建zabbix数据库以及创建授权用户
代码语言：javascript复制mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix'；
mysql> flush privileges;11.编辑zabbix-server配置文件，修改以下参数为创建数据库时的信息，并重启zabbix-server

代码语言：javascript复制systemctl enable zabbix-server
systemctl start zabbix-server12.将初始数据导入MySQL中
代码语言：javascript复制zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix三、安装Nginx
1.关掉防火墙和selinux
代码语言：javascript复制systemctl stop firewalld

make && make install
echo $? #每执行完上条命令就运行一下，如果返回0，则执行成功
cp php.ini-production /usr/local/php/etc/php.ini4.更改PHP配置文件
代码语言：javascript复制sed -i 's/post_max_size = 8M/post_max_size = 32M/g' /usr/local/php/etc/php.ini
sed -i 's/upload_max_filesize = 2M/upload_max_filesize = 50M/g' /usr/local/php/etc/php.ini
sed -i 's/;date.timezone =/date.timezone =PRC/' /usr/local/php/etc/php.ini

sed -i 's/max_input_time = 60/max_input_time = 600/g' /usr/local/php/etc/php.ini
sed -i 's/memory_limit = 128M/memory_limit = 256M/g' /usr/local/php/etc/php.ini
sed -i 's/; max_input_vars = 1000/max_input_vars = 10000/g' /usr/local/php/etc/php.ini5.启动php-fpm
代码语言：javascript复制cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
/usr/local/php/sbin/php-fpm -c /usr/local/php/etc/php.ini -y /usr/local/php/etc/php-fpm.conf五、安装zabbix-agent
代码语言：javascript复制yum install zabbix-agent
vim /etc/zabbix/zabbix-agentd.confServer和ServerActive分别代表zabbix的被动模式和主动模式，这里都填server端的IP 最后一行是开启脚本采集数据
六、安装zabbix-web
1.将zabbix的php源文件拷贝到网站目录上
代码语言：javascript复制cp -r /usr/share/zabbix/.* /usr/share/nginx/html/2.修改nginx配置
代码语言：javascript复制egrep -v '(^.*#|^$)' /etc/nginx/conf.d/default.conf
server {
listen 80;
server_name 192.168.179.133;
access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm index.php;
}
location /zabbix {
root /usr/share/nginx/html;
index index.html index.htm index.php;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ .php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
include fastcgi_params;
}
}
3.授予zabbix-web目录权限并重启nginx
代码语言：javascript复制chmod -R 777 /etc/zabbix/web.
chmod -R 777 /usr/share/nginx/html/zabbix
systemctl restart nginx4.在浏览器上访问192.168.179.133/zabbix开始安装zabbix-web
七、升级zabbix
1.停止zabbix-server和zabbix-proxy
由于我是本地测试环境，没装proxy，所以只停server
代码语言：javascript复制systemctl stop zabbix-server2.备份4.0配置数据
代码语言：javascript复制mysqldump -uzabbix -p --single-transaction --master-data=2 --databases zabbix > olddata.sql3.更新存储库配置包
代码语言：javascript复制rpm -Uvh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-1.el7.noarch.rpm4.升级Zabbix组件
代码语言：javascript复制yum upgrade zabbix-server-mysql zabbix-web-mysql zabbix-agent5.启动Zabbix-server进程
代码语言：javascript复制systemctl start zabbix-server6.授予zabbix-web权限
代码语言：javascript复制chmod 777 -R /etc/zabbic/web7.将生成的前端文件放在网站目录下
当时这里做了三次才想到，之前一直以为是数据库的问题，后来一想数据库是4020000，而前端是4000000，说明数据库是4.2的了，有问题的应该是前端，又想到前端已经生成好了，只不过没拷贝到网站目录下而已
cp -r /usr/share/zabbix/.* /usr/share/nginx/html/至此，zabbix4.0升级到4.2完成
