Zabbix部署之安裝mysql


#安裝MYSQL,包從官網下的
rpm -ivh perl-JSON-2.59-2.el7.noarch.rpm
rpm -ivh libaio-0.3.109-13.el7.x86_64.rpm
#刪除之前安裝的包,否則會衝突
yum remove -y mariadb-libs
rpm -ivh mysql-community-common-5.7.27-1.el7.x86_64.rpm
rpm -ivh mysql-community-embedded-5.7.27-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-compat-5.7.27-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.27-1.el7.x86_64.rpm
rpm -ivh mysql-community-embedded-devel-5.7.27-1.el7.x86_64.rpm

rpm -ivh mysql-community-test-5.7.27-1.el7.x86_64.rpm

#開啓服務
systemctl enable mysqld
systemctl start mysqld

#保存初始密碼
temppassword=`cat /var/log/mysqld.log  |grep password |awk -F ": " '{print $2}'`

#利用臨時密碼登陸,這種方法很好,記住

#更改目錄權限 及重啓各種服務
chown -R nginx:nginx /etc/zabbix/web

#這時注意   /usr/local/nginx/conf/zabbix.conf 的配置文件中的 各種目錄是否正確
#zabbix默認web目錄在  /usr/share/zabbix裏  ,而不在 在/usr/local/nginx/html中

Zabbix部署之安裝PHP

Zabbix部署之安裝Nginx


#安裝所需軟件
yum install -y pcre pcre-devel openssl openssl-devel

##添加需要的用戶
useradd -M -s /sbin/nologin nginx
./configure --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --prefix=/usr/local/nginx/
make && make install 
ln -s /usr/local/nginx /server/app/nginx

#開啓NGINX
/usr/local/nginx/sbin/nginx

#nginx 開機啓動
chmod +x /etc/rc.local
echo "/usr/local/nginx/sbin/nginx" >> /etc/rc.local

#創建子配置文件目錄
mkdir -p /usr/local/nginx/conf/extra

#寫入conf/extra/phpinfo.php,爲了測試
echo "
server {
listen 80;
server_name test.zabbix;
location / {
root /usr/local/nginx/html;
index index.html index.htm index.php;
}
error_page 500 502 503 504 /50x.html;

Zabbix部署之常見問題

zabbix安裝配置彙總
###非常重要,server agent端一定在同一源來安裝,版本最好相同,即使不相同也一定保證是同一個源,否則會出問題,被坑過

PHP databases support off Fail 編譯 ./configure --with-php-config=/usr/local/php/bin/php-config --with-mysqli=/usr/local/mysql/bin/mysql_config
有可能報錯,取消掉--with-mysqli 選項,並在 php.ini 設置 extensions=mysqli.so

2.php.ini 設置 always_populate_RAW_post_data = -1 (在PHP.INI中,-1 爲關閉 0爲開啓目前看是這樣)

3.zabbix Error connecting to database: No such file or directory 在php.ini 中 mysqli_default_sock = 指定mysql.sock的位置

4.zabbix 默認賬號 Admin 密碼 zabbix 注意,區分大小寫
zabbix 更改密碼,庫裏密碼是MD5加密的

   use zabbix;
   select * from zabbix.users\G;
   echo 123 | md5sum
   update users set passwd='5fce1b3e34b520afeffb37ce08c7cd66' where userid='1';

5.web界面無法選擇中文 php缺少gettext 模塊編譯
cd /server/data/php/ext/gettext
phpize
./configure --with-php-config=/usr/local/php/bin/php-config
vim /server/app/php/lib/php.ini
添加 extension=gettext.so

同時保證 /usr/share/zabbix/include/locale.XXX 文件裏簡體中文是true狀態
