一、系统环境配置
1.修改/etc/sysctl.conf
fs.file-max = 655350 net.ipv4.ip_local_port_range = 1024 65535 net.ipv4.tcp_max_tw_buckets = 2000 net.ipv4.tcp_tw_recycle = 1 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_syncookies = 1 net.ipv4.tcp_syn_retries = 2 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_keepalive_time = 1200 net.ipv4.tcp_fin_timeout = 15 net.ipv4.tcp_max_syn_backlog = 20000 net.core.somaxconn = 65535 net.core.netdev_max_backlog = 65535
[root@zabbix ~]# sysctl -p
2.修改limits.conf修改
[root@zabbix~]# vim /etc/security/limits.conf * soft nproc 65535
* hard nproc 65535
* soft nofile 65535
* hard nofile 65535 #保存退出 [root@zabbix ~]# vim /etc/pam.d/login session required pam_limits.so
3.关闭防火墙和selinux
[root@zabbix ~]#systemctl stop firewalld [root@zabbix ~]#systemctl disable firewalld #关闭selinux [root@zabbix ~]#sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config [root@zabbix ~]#setenforce 0
系统调整完成
二、lnmp环境搭建
1.安装nginx
#下载地址：http://nginx.org/download/nginx-1.19.9.tar.gz
#配置本地阿里云yun源
[root@zabbix ~]# cd /etc/yum.repos.d/
[root@zabbix yum.repos.d]# mkdir bk && mv * bk/
[root@zabbix yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
安装依赖包
[root@zabbix src]# yum install pcre-devel openssl-devel zlib-devel gcc* -y
# pcre 支持正则表达式 # zlib 支持数据压缩 # openssl支持HTTPS
开始安装
[root@zabbix nginx-1.19.9]# goupadd -g 501 nginx [root@zabbix nginx-1.19.9]# useradd -u 501 -g 501 -s /sbin/nolog nginx [root@zabbix nginx-1.19.9]# cd /usr/local/src
[root@zabbix nginx-1.19.9]# tar xf nginx-1.19.9.tar.gz
[root@zabbix nginx-1.19.9]# cd nginx-1.19.9
[root@zabbix nginx-1.19.9]# ./configure --prefix=/u01/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --with-http_realip_module --with-pcre
# --with-http_ssl_module 启用HTTPS加密 # --with-http_stub_status_module 启用nginx状态监控 # --with-http_gzip_static_module 启用静态压缩 # --with-http_realip_module 做代理时获取客户端真实IP
# 这里说下，在编译之前需要安装编译支持环境
[root@zabbix nginx-1.19.9]# make && make install
启动重启
/u01/nginx/sbin/nginx -c /u01/nginx/conf/nginx.conf
/u01/nginx/sbin/nginx -s reload
通过客户端访问正常
2.安装mysql8.0
下载mysql二进制包，以及安装mysql依赖包
#安装mysql所需依赖包 [root@zabbix src]# yum install libaio* -y #下载mysql二进制安装包 [root@zabbix src]# wget http://mirrors.163.com/mysql/Downloads/MySQL-8.0/mysql-8.0.14-linux-glibc2.12-x86_64.tar.xz #卸载系统自带mysql/mariadb [root@zabbix src]# rpm -qa | grep mysql [root@zabbix src]# rpm -qa | grep mariadb [root@zabbix src]# rpm -e --nodeps mysql [root@zabbix src]# rpm -e --nodeps mariadb
创建mysql用户和组
[root@zabbix src]# groupadd mysql [root@zabbix src]# useradd -r -g mysql -s /sbin/nologin mysql
解压mysql安装包并移至相关目录
#解压 [root@zabbix src]# tar xf mysql-8.0.14-linux-glibc2.12-x86_64.tar.xz #移动 [root@zabbix src]# mv /usr/local/src/mysql-8.0.14-linux-glibc2.12-x86_64 /u01/mysql
创建Mysql所需data和log目录
[root@zabbix src]# mkdir -p /u01/mysql/data [root@zabbix src]# mkdir -p /var/log/mysql [root@zabbix src]# chown -R mysql:mysql /u01/mysql/data [root@zabbix src]# chown -R mysql:mysql /var/log/mysql [root@zabbix src]# chmod -R 755 /u01/mysql/data [root@zabbix src]# chmod -R 755 /var/log/mysql
配置/etc/my.cnf文件
[mysql] socket=/tmp/mysql.sock defalut-character-set=utf8 [mysqld] character-set-server=utf8 port=3306 basedir=/ointall/mysql datadir=/oradata/data log-error=/var/log/mysql/error.log user=mysql default_authentication_plugin=mysql_native_password skip_host_cache skip-name-resolve=1 #skip-grant-tables default_storage_engine=InnoDB
初始化数据库，这里生成的密码在后面登陆的时候并没用，所以记不记没什么关系
[root@zabbix mysql]# /u01/mysql/bin/mysqld --initialize --user=mysql --basedir=/u01/mysql/ --datadir=/u01/mysql/data/
制作启动文件
cp -a /ointall/mysql/support-files/mysql.server /etc/init.d/mysqld #更改启动文件路径 vim /etc/init.d/mysqld 将basedir更改为basedir=/ointall/mysql 将basedir更改为basedir=/ointall/mysql/bin 将datadir更改为datadir=/oradata/data #授予mysqld执行权限 chmod -R 755 /etc/init.d/mysqld #启动mysql服务 /etc/init.d/mysqld start #创建软连接，也就是windows里面的快捷方式 ln -vs /ointall/mysql/bin/mysql /usr/bin
注：如果所有操作，所有配置文件都没有错误的情况启动报如下错误，
Starting MySQL.Logging to '/var/log/mysql/error.log'. ERROR! The server quit without updating PID file (/oradata/data/rabbitmq.pid). 尝试用一下方法解决，具体原因不得而知。 /u01/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf
到这里，mysql安装已经全部结束。接下来是登陆问题，安装完mysql后无法正常登陆，不管是随机密码。还是空密码都不行
[root@zabbix bin]# mysql ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO) [root@mysql bin]# mysql -uroot -prgVLupUj0W# mysql: [Warning] Using a password on the command line interface can be insecure. ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) [root@zabbix bin]# mysql -uroot -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
#这时候我们修改/etc/my.cnf配置文件，在[mysqld]里面加一条如下参数。上的配置文件我已经给出了，只要去掉注释即可
skip-grant-tables
#重启mysql服务
/etc/init.d/mysqld restart
重新登陆mysql，按照下面的步骤进行修改密码
[root@zabbix bin]# mysql Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 7 Server version: 8.0.14 MySQL Community Server - GPL Copyright (c) 2000, 2019, Oracle and/or its affiliates. All rights reserved.

Type 'c' to clear the current input statement. mysql> flush privileges; Query OK, 0 rows affected (0.01 sec) mysql> alter user 'root'@'localhost' identified by 'Newings@123'; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql> exit Bye
3、安装php7.3
#先去这个网址下载加密包 https://centos.pkgs.org/ libmcrypt-2.5.8-4.el7.art.x86_64.rpm libmcrypt-devel-2.5.8-4.el7.art.x86_64.rpm mhash-0.9.9.9-3.el7.art.x86_64.rpm mhash-devel-0.9.9.9-3.el7.art.x86_64.rpm
[root@zabbix rpm]# chmod u+x *
[root@zabbix rpm]# rpm -ivh *
#安装cmake编译工具[root@zabbix src]# wget https://cmake.org/files/v3.11/cmake-3.13.2.tar.gz
[root@zabbix src]# tar xzvf cmake-3.13.2.tar.gz
[root@zabbix src]# cd cmake-3.13.2
[root@zabbix cmake-3.13.2]# ./bootstrap
[root@zabbix cmake-3.13.2]# gmake
[root@zabbix cmake-3.13.2]# gmake install
#下载libzip安装包
[root@zabbix src]# curl -O https://libzip.org/download/libzip-1.5.1.tar.gz

--with-mhash --without-pear --with-gettext --disable-rpath --disable-fileinfo
# 在检查期间，会提示少模块或者文件，缺少什么就安装那个包就好
[root@zabbix php-7.3.27]# make && make install
#时间比较久
[root@zabbix php-7.3.27]# cp -a sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
[root@zabbix php-7.3.27]# chmod +x /etc/init.d/php-fpm
[root@zabbix php-7.3.27]# cp -a php.ini-production /u01/php/etc/php.ini
[root@zabbix php-7.3.27]# cd /u01/php/etc
[root@zabbix php-7.3.27]# cp -a php-fpm.conf.default php-fpm.conf
[root@zabbix php-7.3.27]# cd cd php-fpm.d/
[root@zabbix php-fpm.d]# cp www.conf.default www.conf
#编辑www.conf,将user=www和group=www作如下修改
user=nginx
group=nginx
#启动php,如未正常启动，请看日志
[root@zabbix php-fpm.d]# /etc/init.d/php-fpm start
[root@zabbix php-fpm.d]# netstat -ntplu | grep php-fpm
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 2512/php-fpm: pool
5.修改nginx配置文件
user nginx nginx; worker_processes 2; error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; pid logs/nginx.pid; worker_rlimit_nofile 65535; events { use epoll; multi_accept on; worker_connections 1024; } http { include mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log logs/access.log main; open_log_file_cache max=1000 inactive=20s min_uses=2 valid=1m; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; limit_conn_zone $binary_remote_addr zone=addr:5m; limit_conn addr 100; sendfile on; tcp_nopush on; tcp_nodelay on; #keepalive_timeout 0; keepalive_timeout 65; client_header_timeout 2m; client_body_timeout 3m; reset_timedout_connection on; send_timeout 15s; open_file_cache max=65535 inactive=20s; open_file_cache_valid 30s; open_file_cache_min_uses 2; open_file_cache_errors on; gzip on; gzip_disable "msie6"; gzip_proxied any; gzip_comp_level 4; gzip_vary on; gzip_min_length 1k; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; server { listen 80; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { #root html; root /u01/nginx/html; index index.html index.htm index.php; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ .php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ .php$ { root html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; #fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} }
测试php异界mysql是否正常，注意mysql5和8所用的函数不一样
[root@zabbix html]# vim test.php
<?php
$conn=mysqli_connect('localhost','zabbix','root@123');
if ($conn)
echo "success.";
else
echo "fail.";
?>
php信息
[root@zabbix html]# vim index.php
<?php
phpinfo()
?>
三、安装zabbix
安装jdk

浏览器输出ip/zabbix/setup.php开始配置zabbix
必要条件，如有fail，则去调整php.ini对应参数
配置DB连接
zabbix详细信息
界面设置
安装汇总
完成配置，
用户：Admin
默认密码：zabbix
至此，zabbix已完成安装
接下来是Grafana的安装及配置
